A piston head has opposite fluid drive surfaces and is enclosed in a cylinder housing also having opposite fluid drive surfaces. The piston head is secured to a piston rod anchored at one end to a stationary support whereby the piston head and cylinder housing produce driving movement of the cylinder housing. The cylinder housing has a work engaging arm on the exterior thereof. Fluid supply conduits lead into the piston head and open between the fluid drive surfaces. Control valves are provided between a pressured fluid supply and the piston head and include cycling controls providing advancing and retracting movement of the cylinder housing for reciprocating operation of the work engaging arm. A cycling operation is initiated by a normally closed spring return operating valve.

A mirror frame is pivotally supported on an upright shaft arranged to have an integral, non-rotatable securement to mirror bracket arms of a vehicle. The upright shaft has a radially projecting arm with threaded connection to a cross shaft driven by a reversible motor supported on such shaft. The end of the cross shaft opposite from its drive connection with the upright shaft has a rotatable support at a laterally offset point on the mirror frame to provide rotation of the mirror frame relative to the upright shaft upon operation of the motor. The bearing connection of the cross shaft with the mirror frame is one which allows adjustment about a vertical axis but one which prevents axial movement of the shaft.

An elongated cylinder housing has a piston therein molded from a resinous plastic material. The piston has an angularly extending slot receiving a metal clutch roller operated by a clutch control bar slidable relative to the piston. The clutch control bar is secured to a secondary piston member, and springs are disposed between the piston and the secondary piston member for normally causing the control bar to pull the clutch roller into an engaged position. The clutch roller is disposed in such engaged position to prevent travel of the piston in one direction except when actuating fluid in the cylinder operates on the secondary piston member against the force of the springs to cause the clutch roller to move the clutch control bar into a released position. The bottom of the slot that receives the clutch roller is covered by metal plates to permit free rolling engagement of the clutch roller thereon and at the same time to prevent indentation of the clutch roller into the plastic. The roller support plates are retained in the slot by interfitting projections and notches.
