<p>One-way clutch 18 has a spring the elastic modulus of which is limited up to a predetermined value, seal rings 36a, 36b have a sliding resistance with respect to the inner rings 22 which is limited up to a predetermined value, and support bearings 17a, 17b have a rotation resistance which is limited up tp a predetermined value. The torque required to rotate the driven pulley 7a relative to the sleeve 8a in the direction for overrun condition is limited up to 0.5 N.m. Accordingly, the power generating efficiency of the alternator is secured while abnormal sounds are prevented from occurring with the life of endless belt being prevented from reducing. <IMAGE></p> |
