ABSTRACT:
An adjusting mechanism of a lens barrel of a camera, including a lens supporting member which supports a photographing optical system, a camera body which supports the lens supporting member in a movable fashion in an optical axis direction of the photographing optical system, and a spring member for biasing the lens supporting member forwardly in the optical axis direction. The mechanism further includes a connecting member which restricts a movement of the lens supporting member to a maximum projecting position against a restoring force of the spring member in the optical axis direction with respect to the camera body while permitting the lens supporting member to move rearwardly against the restoring force of the spring member in the optical axis direction.
