Abstract: A centrifugal clutch 200 includes a first drive plate 210 rotationally driven directly by a driving force of an engine and a second drive plate 220 frictionally in contact with the first drive plate 210. The first drive plate 210 includes a bulging body 215 on a supporting portion 214 bulging toward the second drive plate 220. The second drive plate 220 is rotationally driven together with the first drive plate 210 while allowing rotational displacement relative to the first drive plate and includes clutch weights 230. The bulging body 215 is made of a cylindrical roller. The clutch weight 230 is formed with a driven portion 232. The driven portion 232 has a pressing body 232a in contact with the bulging body 215. The pressing body 232a obliquely extends rearwardly and outwardly in a rotational drive direction of the first drive plate 210.

Abstract: A power transmitting apparatus has a clutch member and a pressure member. The cam surfaces of the pressure-contact assist cam face each other. The cam surfaces of the back torque limiter cam face each other. A receiving portion for a clutch spring (10) on the pressure member (5) side has a receiving member (11) separate from the pressure member (5). A first cam surface (C1) and a second cam surface (C2), constituting the back torque limiter cam, are, respectively, formed on the receiving member (11) and the clutch member (4). A third cam surface (C3) and a fourth cam surface (C4), constituting the pressure-contact assist cam, are, respectively, formed on the pressure member (5) and the clutch member (4).

Abstract: A transmission device has a clutch spring (8). The clutch spring (8) can generate rotational resistance that occurs when a pressure member (5) rotates relative to a clutch member (4) due to clearance between cam surfaces of a press-contact assisting cam or a back torque limiting cam. Thus, one end (8a) of the clutch spring (8) slides on a surface (10a) of a restricting member 10. A side surface (8b) of the clutch spring (8) is held in the longitudinal direction.
