Abstract
A lens mounting includes a movable cam having a cam portion formed to a convex shape, an axially movable member having a cam follower portion sliding on one of side surfaces of the convex cam portion of the cam in which a cam lift is formed. A lens is arranged to move axially in response to axial movement of the axially movable member, and a leaf spring pressing the other side surface of the convex cam portion urges the cam follower portion toward the one side surface of the convex cam portion. The leaf spring has its pressing portion at a position of the convex cam portion and is fixed to the axially movable member at a position displaced to a direction almost perpendicular to the optical axis from the pressing portion.
