<p><P>PROBLEM TO BE SOLVED: To provide a power transmission device for a compressor always capable of excellently transmitting power, without transmitting fluctuation of rotating speed to a transmitting member, the fluctuation being exerted by a power source to a pulley. <P>SOLUTION: A one-way clutch 30 is provided between the pulley 20 and a torque plate 50 to transmit the only rotating speed of the pulley 20 in one way to the torque plate 50. Even in the case wherein power from a power source such as an internal combustion engine, of which rotating speed changes in a short period, is transmitted to the pulley 20, rotating force when the rotating speed is lowered is not transmitted to the torque plate 50, and inertia torque of a rotating member of the compressor to be generated by lowering of the rotating speed is reduced to reduce vibration and noise of the compressor. Since the one-way clutch 30 is arranged between a pulley main body 21 and a support part 22, axial dimension of the whole of the power transmission device can be reduced to save space. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
