PURPOSE:To improve durability while restrain noise of titled gear by installing a one-way clutch which is allowed to rotate in the same direction as that of the input shaft of a stater member, between said stater member and a fixed shaft in a planetary gears. CONSTITUTION:When the rotating speed of an engine E is low, a rotating torque is transmitted to an auxiliary machine through a centrifugal clutch Cc, a housing 8, a pulley 7, and a belt 19. In this case, a loading torque is not applied to the meshing part between the internal gear 44 and the planetary gear 46 and the meshing part between the planetary gear 46 and the sun gear 45, of planetary gears Gp. Then, as the rotating speed of an input shaft 6 is increased and the direct engagement between the input shaft 6 and the housing 8 by means of the centrifugal clutch Cc is released, since a one-way clutch Co checks the rotary motion in the reversal direction to the input shaft 6 of the sun gear 45, the sun gear 45 is stopped. As a result, the rotating torque of the input shaft is transmitted to the pulley 7 with a peculier reduction ratio to the planetary gears Gp, without providing more than necessary rotating speed to the auxiliary machine. |
