Abstract:
1. A lens barrel, comprising: a first optical element group that comprises an optical element disposed on a first optical axis; a second optical element group that comprises an optical element disposed on a second optical axis extending along a direction different from a direction along which the first optical axis extends; a bending portion disposed between the first optical element group and the second optical element group, that bends image light having passed through the first optical element; a first cam cylinder that houses the first optical element group and moves the first optical element group along the first optical axis; a second cam cylinder that moves the bending portion and the second optical element group along the second optical axis; and a fixed cylinder with the first cam cylinder disposed therein, that is connected with the second cam cylinder, wherein: when the lens barrel shifts from a photographing position at which photographing operation executed by using the lens barrel is allowed to a storage position at which the photographing operation is not allowed, (a) at least part of the first optical element group is housed inside a first space formed as the bending portion moves further away from the first optical axis and (b) at least part of the bending portion is housed inside a second space formed as the second optical element group moves further toward an image side relative to the photographing position; and the first cam cylinder is housed inside the fixed cylinder at the storage position.
