A body side structure 3 includes an outer panel 4 integratedly formed by press forming, an inner panel 5, and a reinforcement 6. The transmission input member is connected to a dry launch clutch. A pivotal tab on the support frame is received in one of a plurality of detents on the lens frame for releasably securing the lens frame in the desired position on the support frame. The outer mount, the rotatable carrying ring and the connecting members are constructed as rotatable kinematics in the form of parallel kinematics. Uplift of the brake shoe from the backing plate is prevented by engagement between the guide surface and the engagement projection.
