潼关吏摘要：A mechanism for coupling a motor to a driving element for actuating an attached member, such as for instance extending and retracting a vehicle radio antenna. A rotatable actuating member is provided for actuating the driving element. Clutching means operates to clutch the rotatable actuating member to the motor for drivingly rotating the actuating member. The clutching means including a rotatable clutch member coupled to the motor. The rotatable actuating member and the clutch member have abutments thereon, which abutments when dispod in confronting engaged relation, cau rotation of the actuating member upon rotation of the motor driven clutch member. The abutments are staggered with respect to the axes of rotation of the clutch and actuating members for driving of the actuating members in both rotary directions. Ramp-like structure coacts with the abutments on one of the members for preventing noisy movement of the abutments relative to one another in the event that the driving connection between the clutch member and the actuating member is relead when the stress between the abutments results in an overload, causing the abutments on one of the members to ride over the confronting abutments on the other of the members, and thereby providing smooth, substantially noiless overload relea for the mechanism.
