A height dimension of the actuator main section is smaller than a front-back dimension of the actuator main section.

Electric shaver

An electric shaver includes a rod-shaped body part, a head part, and an interposer. The head part projects from one end portion, in a longitudinal direction, of the body part and swingably attached to the body part. The head part includes a shaving portion and a drive mechanism. The interposer is configured to support the head part swingably about a first swing axis parallel with a longitudinal direction of the shaving portion, and to be supported on the body part swingably about a second swing axis orthogonal to the projecting direction of the head part and orthogonal to the first swing axis.

Barsinclude a hair raising barhaving a hair raising portionraising body hair. A cross section of the hair raising portionhas a profile shape including connecting elementswhich are connected, each connecting element being at least any one of a line segmentand an arc line

Electric Shaver

A blade of a reciprocating electric shaver includes a newly provided guide frame freely detachably held on a holding frame provided on a shaver body, in which, in the guide frame, there are provided: coupling portions to which an outer edge frame that fixes an outer edge thereto is coupled; and spring receiving portions which support lower ends of inner edge push-up springs.

Blade of reciprocating electric shaver

An electric shaver includes: a main body; an outer blade provided to an end of the main body and having a blade hole defined by a bar; and an inner blade provided inward of the outer blade and configured to reciprocate in a longitudinal direction of the outer blade to cut hair in the blade hole with the outer blade. The bar has a hair raising portion coming in contact with hair upon movement of the outer blade on a skin surface to raise hair up from the skin surface. A contact pressure on the skin surface to be exerted by the outer blade in a first portion of the outer blade is greater than that in a second portion of the outer blade. Hair raising performance in raising hair up from the skin surface in the first portion is smaller than hair raising performance in the second portion.

An electric shaverincludes: outer bladeshaving blade holesdefined by bars; and inner bladeswhich is provided inside of the outer bladesand moved relative to the outer bladesto cut body hairinserted into the blade holes. A first barin which a skin contact surfacecoming into contact with skinis positioned on the inner bladeside of a skin contact surfaceof a hair raising baris provided adjacent to and forward of the hair raising bar

An electric shaver including: a gripper portion to be held by the user's hand; and a head portion configured to hold a shaving-blade unit and supported to be swingable in predetermined directions with respect to the gripper portion, wherein the head portion is provided with an edge-trimmer-blade unit.

An electric shaver includes a rod-shaped body part, a head part, and a link mechanism. The head part projects from one end portion of the body part and is swingably attached to the body part with a support base between the body part and the head part. The head part includes a shaving portion and a drive mechanism. The shaving portion is elongated in a direction orthogonal to a projecting direction of the head part and has paired blades configured to operate relative to each other. The drive mechanism is configured to drive at least one of the paired blades. The link mechanism includes two link arms each connected to the support base and the head part respectively at connecting axes parallel to a longitudinal direction of the shaving portion. The link mechanism is configured to support the head part on the support base swingably.

An electric shaver including: a gripper portion to be held by the user's hand; and a head portion configured to hold a shaving-blade unit and supported to be swingable in predetermined directions with respect to the gripper portion, wherein the head portion is provided with: an edge-trimmer-blade unit configured to be switched between a ready-for-use state and a stored state by an operation element; and a engaging portion for fixing the head portion, the engaging portion configured to be engaged with the operation element when the edge-trimmer-blade unit is switched to the ready.

An electric shaver includes a rod-shaped body part, a head part, and a link mechanism. The head part projects from one end portion, in a longitudinal direction, of the body part and is swingably attached to the body part with a support base between the body part and the head part. The head part includes a shaving portion and a drive mechanism. The shaving portion is formed to be elongated in a direction orthogonal to a projecting direction of the head part and has paired blades configured to operate relative to each other. The drive mechanism is configured to drive at least one of the paired blades. The link mechanism includes two link arms each connected to the support base and the head part respectively at connecting axes parallel to a longitudinal direction of the shaving portion. The link mechanism is configured to support the head part on the support base swingably. The two link arms are disposed asymmetrically with respect to a straight line passing on a center of gravity of the head part and extending parallel with the projecting direction of the head part, when viewed in the longitudinal direction of the shaving portion.

An electric shaver in which a blade frame part is attached to an upper portion of a body part, the blade frame part including an outer blade, an outer blade frame to fix the outer blade thereto, a holding frame to hold the outer blade frame vertically movable, and an outer peripheral frame connected to the holding frame, the upper portion including an inner blade. The holding frame is detachably attached to the outer peripheral frame from an under side thereof, and the outer peripheral frame entirely covers an outer periphery of the holding frame.

An inner cutter of an electric shaver that cuts hairs by sliding along an inner surface of an outer cutter includes a base portion that is connected to a driving unit, a plurality of cutting pieces that are formed in a U-shape and whose both ends in the longitudinal direction are fixed to the base portion, and a plate member whose one end is fixed to the base portion and the other end is connected to the cutting piece. The plate member is elastically deformed corresponding to elastic deformation of the cutting piece.

Inner cutter of electric shaver and reciprocating electric shaver

A dry shaver has an elongated shaving head with a lengthwise axis. The shaving head carries semi-cylindrical first and second outer cutters disposed on its opposite width ends, and a semi-cylindrical finishing cutter and a slit cutter interposed between the first and second outer cutters. The finishing cutter has a finishing foil which is deeply curved than a foil of the first and second outer cutters into an arcuate contour having a width less than that of the first and second outer cutters. The finishing foil disposed behind the first outer cutter comes into contact with a users skin to make closer shaving than the first and second cutters. A skin guard project between the first outer cutter and the finishing cutter to protect the skin from being pressed excessively to a side of the finishing foil when moving the shaving head across a user' skin with the first outer cutter leading in a moving direction, thereby reducing skin irritation.

Dry shaver

An electric shaver includes net-shaped outer blades; and inner blades sliding reciprocally over an inner side of the outer blades as detachably connected with driving units driven by a motor. Each of the inner blades includes a blade plate having an inversed-like-U shape seen from a longitudinal direction in parallel with a reciprocating sliding direction; and a blade holder having attaching portions to be attached to the blade plate in longitudinally defined end regions, wherein connection portions to be detachably connected with the driving units are provided at the blade holder in a longitudinally defined center region, and, when dissembling the blade holder from the driving units, anti-detach portions are provided to thereby prevent separation of the blade holder in the longitudinally defined center region from the blade plate in the longitudinally defined center region due to a tensile load between the connection portions and the driving units.
