    摘要: A clutch mechanism suitable for connecting a rotatable member to an output shaft of a motor, which mechanism comprises a body which is attachable to the output shaft and a resilient arm, one end of which is fixed to the body the other end of which is capable of engaging the rotatable member or part thereof, wherein the body is capable of gripping the output shaft in secure frictional contact to transfer rotational drive from the output shaft to the rotatable member only when the rotatable member is not restrained against rotation.
