摘要： A cam mechanism includes a cam ring having front and rear cam grooves which have a common reference cam diagram and are formed so that a front part of the front cam groove and a rear part of the rear cam groove are omitted from the reference cam diagram. A normal-width section and a wide-width section are provided in each of the front and rear cam grooves. In a zoom range, an associated cam follower of a driven member is engaged in the normal-width section of one of the front and rear cam grooves, and another associated cam follower of the driven member is positioned out of the other of the front and rear cam grooves. In a transition state between the zoom range and an accommodated position, both of the associated cam followers are positioned out of the normal-width sections of the respective front and rear cam grooves.
