PURPOSE: To simplify the constitution and also to execute easily the operation by constituting so that a rewinding lever turns automatically and attains a raised state with a rise of a supporting member, by releasing a detainment of the other end of the lever.

CONSTITUTION: A lever supporting member 10 on which one end of a rewinding lever 7 is attached pivotally so as to be rotatable to the upper end part is supported so as to be movable up and down in a through-hole 6b of a rewinding knob 6, and energizing force in the upper direction is always applied to the lever supporting member 10 by a plate spring 11 provided in the rewinding knob 6. When photographing is ended and a film rewinding operation is executed, it is executed by inserting a pawl, etc. into a gap between the tip of the rewinding lever 7 and an engaging groove 8a of a film sensitivity display dial 8, and pushing up the rewinding lever 7. As a result, a click spring 16 is detached from a detaining groove 15a of a knob 15, therefore, the lever supporting member 10 rises by energizing force of the plate spring 11, following which the rewinding lever 7 is turned toward the upper direction of a camera body, and becomes a raised state.
