A lock device includes a cam portion including a stationary-side cam; a rotor including a movable-side cam; a slide groove; a slide projection; an engagement projection; and a lock groove, in which the movable-side cam is disengaged from the stationary-side cam, so that the rotor rotates so as to allow the engagement projection that has been fitted in the lock portion to disengage from the lock portion. The urging device includes a spring, and a sleeve inserted to pass through a lower-side rod portion, positioned between the rotor and the spring, and also restricting a movement of the rod in a sliding direction in a lock position of the lock device (for example, a lock groove and an engagement projection, and the like).

Push-up device

A damper unit includes a gear having a core member projecting at a shaft core portion thereof and rotatably housed in a case, a string wound around the core member, a rotary damper engaging the gear for damping a rotational force of the gear, and a spring. One end of the spring is fixed to the case and the other end thereof is fixed to the core member so that an elastic force is accumulated when the string is pulled out.

Oil damper

A damping structure is formed of a base including at least one projecting portion having a shaft or a hole, and a first engaging portion; a rotating member including a first wall portion having the other of the hole or the shaft engaging the shaft or hole, a second wall portion facing the first wall portion to receive the projection therebetween so that when the first wall portion is supported by the projecting portion, a space is formed between the projecting portion and the second wall portion, and a second engaging portion; and a damper disposed in the space. The damper includes an inner shaft having a third engaging portion engaging the first or second engaging portion, and an outer shaft rotatably situated around the inner shaft to generate a damping force against a rotation of the inner shaft. The outer shaft has a fourth engaging portion engaging the first or second engaging portion to thereby provide a damping force to the rotating member.

A latch unit of the invention includes a casing having a holding chamber for holding a striker and a side chamber situated adjacent to the holding chamber, and a responding member housed in the side chamber. The holding chamber and the side chamber are partitioned by an elastic member projecting toward an introduction opening of the holding chamber for introducing the striker to be attached to the latch unit. The electric member is provided with an engaging projection for engaging the striker as the striker is inserted into the holding chamber. The side chamber is provided with an urging device for urging the responding member toward a base portion of the elastic member. An urging force of the urging device is set such that when an inertia force is applied to release an engagement of the elastic member and the striker to thereby extract the striker from the holding chamber, the responding member is allowed to move to a position for preventing the elastic member from being bent toward the side chamber. Thus, engagement of the latch and the striker is not released in case of emergency.

A holding device of a shaft, i.e. a shaft for a sun visor, includes a base and a holder. The base includes a base main portion and anchors. The holder has a holder main portion and a supporting leg. The supporting leg is provided with lock portions on an outer periphery thereof. The lock portions are engaged with a back surface of the base main portion when they are inserted into the inserting hole, and the supporting leg is rotated from an inserted position. Thus, the holding device for the sun visor can be easily attached to a vehicle body.

Holding device for shaft member

A latch device in which joggling of a latch main body is prevented and smooth movement of the latch main body is realized. When the latch main body is pushed-in from a first position of an insertion direction of the latch main body, holding of the first position is cancelled. Due to a spring, a stopper moves in a guide hole and abuts an end of the guide hole and the latch main body reaches a second position at a side opposite an insertion side. If the latch main body is pushed-in from the second position, the latch main body returns to the first position. When the latch main body is pushed-in to the first position and moves, an abutting portion extending from the stopper to a latch main body insertion side slides along an inner surface of a case wall, in a direction in which the stopper fits into the guide hole, along a side edge of the guide hole at a region at which the abutting portion misses the guide hole. In this way, when the latch main body moves from the second position to the first position, the latch main body is prevented from entering into the guide hole.

Latch device

A latch device includes a latch body provided in a housing so as to be movable in an inserted direction in which the latch body is inserted into the housing, and in a withdrawn direction in which the latch body is withdrawn from the housing, and being continuously urged in the withdrawn direction. Further, circulatory cam grooves are also provided in the housing, and a supporting member is inserted into the circulatory cam grooves and circulates and moves in the circulatory cam grooves so as to hold the latch body at an inserted state position and a withdrawn state position.
