PROBLEM TO BE SOLVED: To provide a V-belt pulley device having a limiter mechanism capable of optimizing the set value of limiter operation torque with a simple change of structure to transmit the rotating power of an engine to the drive shaft of a compressor. SOLUTION: The tip part of three pin parts 8 of six pin parts 8 and 9 of an outer hub 6 integrally molded on the circumferential side of the inner hub 5 of an output disc is formed thinly, compared with the tip part of the remaining three pin parts 9. The set value of limiter operation torque can be significantly changed, compared with the case where the thickness of the tip parts of all the pin parts 8 and 9 are constant. Accordingly, when an excessive overload torque exceeding the set value of limiter operation torque is generated between a rotor and the output disc, a plurality of the pin parts 8 and 9 is broken to interrupt the transmission of torque from the rotor to the output disc. |
