PROBLEM TO BE SOLVED: To improve assembly property, and prevent the occurrence of the backlash after assembly, and get desired performance, by forming a projection at one end face of the tongue piece of a stopper, and and also, making the tongue piece have elasticity in axial direction. SOLUTION: A resinous annular stopper 30 is interposed between a unidirectional roller clutch 5 and a pinion 6, and a plurality of tongue pieces are projected outward at the outside periphery, and in assembling 6 stopper 30 is inserted unto a gear cover 17, and a tongue piece is received in a recess. Next, an electromagnetic device 9 is press-fitted until the end face of a holder 25 bumps against the step of the internal surface of a gear cover 17, and then, the electromagnetic device 9 is fixed within the gear cover 17 by calking the gear cover 17 at a plurality of places at the periphery of the end face of a ringshaped disc 26 and catching it with the projection and the step, and the stopper 30 is retained by catching the tongue piece within the recess with the end face of the holder 25 and inner end wall face of the recess. As a result, the tongue piece is elastically supported, and the occurrence of the backlash of the stopper can be prevented, and the desired performance of the electromagnetic device can be obtained, and also the assembly property can be improved. |
