摘要： A lens barrel includes a fixing frame provided with cam grooves formed in an inner circumferential surface of the fixing frame, and a drive frame provided with cam followers formed on an outer circumferential surface of the drive frame and a plurality of engaging teeth to the outer circumferential surface of the drive frame, located on substantially the same circumference as the cam followers. With the drive frame incorporated in the fixing frame, the cam followers are fitted in the cam grooves, drive force is transmitted via the engaging teeth, and the drive frame can move relative to the fixing frame in the optical axis direction of a lens as the cam followers move along the cam grooves. In this lens barrel, cam followers are less likely to come out of the cam grooves.

The drive frame 200 is adapted such that, with the drive frame incorporated in the fixing frame 100, the cam followers 201-203 are fitted in the cam grooves 103-105, drive force is transmitted via the engaging teeth 200a, and the drive frame 200 can move relative to the fixing frame 100 in the optical axis direction of a lens as the cam followers 201-203 move along the cam grooves 103-105. According to the present invention, it is possible to provide a lens barrel in which cam followers are less likely to come out of the cam grooves even in the case where a retainer wall cannot be provided within an area where a cam follower about to fall out is received directly by the wall, or in the case where the retainer wall provided within the area where a cam follower is received directly is not sufficient.

摘要： A lens barrel of the present invention includes: a fixing frame having a plurality of cam grooves that are formed an inner circumferential surface of the fixing frame and also having a protrusion provided between any adjacent two of the cam grooves among a plurality of the cam grooves; and a drive frame having cam followers that are provided to an outer circumferential surface of drive frame, are engaged with the cam grooves, and are movable along the cam grooves. With this configuration, when an external force is applied to the drive frame, an end portion of the drive frame comes into contact with the protrusion to prevent the cam followers from coming out of the cam grooves.

Also provided are a small-sized lens unit by making it collapsible and an image pickup apparatus. The lens unit has: the bending member for bending the light entering from an object along a first optical axis, to the direction of a second optical axis substantially perpendicular to the first optical axis; and a first moving member for moving a first support member, which supports the first lens group, in the direction of the first optical axis to a storage position; a bending member moving member for moving the bending member to an evacuation position in order to create a space for storing the first supporting member; and a first zooming movement member for moving the first supporting member in the direction of the first optical axis in a variable magnification manner. The first zooming movement member, the bending member moving member and the first moving member are driven in this order.
