ABSTRACT:
A linear guiding mechanism of a zoom lens barrel including a stationary barrel which is fixed to a camera body, a cam ring which is threadedly engaged with the stationary barrel on an inside of the stationary barrel, and a linear guiding plate for linearly guiding a photographing optical system in an optical axis direction. The linear guiding plate is movable together with the cam ring in the optical axis direction, and the linear guiding plate is rotatable with respect to the cam ring. A linear guiding portion is provided on the stationary barrel for guiding the linear guiding plate in the optical axis direction. A section of the linear guiding potion is formed as an elongated hole. The remaining section of the linear guiding portion is formed as a blind-end groove on an inner peripheral surface of the stationary barrel.
