A lens barrel includes a first frame body, a second frame body, a support frame, and a retracting lens frame. The support frame is supported by the second frame body and moves with respect to the second frame body within a first plane for image blur correction in an imaging enabled state, the first plane being perpendicular to an optical axis. The retracting lens frame moves around a retraction shaft during a transition period between an imaging enabled state and a housed state, the retraction shaft being substantially parallel to the optical axis. The support frame has a protrusion which comes into contact with a groove included in the first frame body and restricts a movable range of the support frame in the first plane and a second plane that is parallel to the first plane.

The first linking portion links the second region on one side of the main body portion in the optical axis direction. The second linking portion links the second region on the other side of the main body portion in the optical axis direction. The retracting lens frame is disposed between the first linking portion and the second linking portion in a housed state.

A lens holding frame includes a plurality of conical protrusions. The plural conical protrusions include a pitch of greater than or equal to 0.1 mm and less than or equal to 2.0 mm.

The lens barrel includes a support frame and a retracting lens frame. The retracting lens frame is configured to support a lens and move around a retraction shaft with respect to the support frame during a transition period between an imaging enabled state and a housed state. The retraction shaft is substantially parallel to the optical axis. The retracting lens frame includes at least three contact portions. The at least three contact portions is configured to come into contact with the support frame at positions that are different from the retraction shaft. Movement of the retracting lens frame in the optical axis direction is restricted when the contact portions come into contact with the support frame. At least one of the contact portions is provided to the retracting lens frame so as to overlap the lens in a direction perpendicular to the optical axis.

A lens unit has an optical system having at least one lens, a lens holder supporting the optical system and a lens frame having a guide component. The guide component guides a movement of the lens holder in a first direction. The lens holder has a first portion and a second portion. The first portion is disposed slidably over the guide component. The second portion is disposed slidably over the guide component and disposed spaced apart from the first portion in the first direction. The guide component is sandwiched between the first portion and the second portion by an elastic force of the first portion and/or the second portion.

Lens unit

An attachment structure is configured to attach a first member to a second member. The attachment structure includes a first engagement portion which is provided at one of the first member or the second member, and a second engagement portion which is provided at the other one of the first member or the second member and which engages with the first engagement portion at a predetermined attachment position to restrict a relative movement. One of the first member or the second member at which the second engagement portion is provided, is provided with spaces at both sides of the second engagement portion in the circumferential direction. The first member and the second member include a torque change portion which changes a torque such that the torque is larger at a preceding side and a succeeding side of the attachment position in the circumferential direction, than at the attachment position.

Attachment structure and lens unit

A lens barrel includes a first support frame and a second support frame. The first support frame has a cam groove. The second support frame has an annular main body with a cam follower that extends outwardly in a radial direction. The cam follower is slidably disposed in the cam groove and has a first cam portion, a second cam portion and a connecting portion. The second cam portion is aligned with the first cam portion along the circumferential direction of the main body. The connecting portion connects the first cam portion and the second cam portion to create a space between the connecting portion and the cam groove.

Lens barrel and imaging device

A lens barrelaccording to the present invention includes: a lens groupwhich moves along an optical axis direction; and a lens holding frameholding a lens group. A guide holeis provided in the lens holding frame, the guide holebeing penetrated by a main shafthaving a circular cross section. A cross section of the guide holetaken orthogonal to a longitudinal direction of the main shaftincludes at least two linear portions, and the main shaftis in contact with the two linear portions

To produce a subject's image on an imager as accurately as possible, a technique that is effectively applicable to the process of assembling an optical system is provided. An imaging device includes: an imager; a plate member, to which the imager is attached; and a holding member configured to hold the plate member. The plate member has a first portion, through which at least one fixing hole has been cut, and a second portion, to which the imager is attached and through which at least one adjusting hole has been cut. The plate member is held by the holding member using a number of fastening members to be introduced through the at least one fixing hole and the at least one adjusting hole. When the first portion is fixed on the holding member, the fastening member that is introduced through the at least one adjusting hole adjusts the relative position of the second portion to the holding member.

Imaging device

A barrier unit, of which the cap edge is not easily deformed even under some external force, is provided.
