Abstract
A position adjusting apparatus for adjusting a position of a lens frame of a camera, which holds a focusing lens group, in an optical axis direction. This apparatus includes a lens frame supporting member which is rotatable relative to the lens frame, a guide which moves the lens frame in the optical axis direction during the rotational adjustment of the lens frame, and a friction mechanism which normally prevents the lens frame and the lens frame supporting member from rotating relative to each other due to a frictional force, and which permits the lens frame and the lens frame supporting member to rotate relative to each other against the frictional force when a predetermined adjusting force is applied thereto.
