POWER TRANSMISSION MECHANISM

摘要

When power is transmitted from a pulley (32) of an engine (E) to a receiving member (35) of a compressor, a power transmitting arm (42) is elastically deformed by force generated by transmission torque. The power transmitting arm (42) thus permits an engaging recess (43) to change its position with respect to the receiving member (35). Accordingly, the pulley (32) and the receiving member (35) are permitted to rotate relative to each other in a predetermined angular range with a roller (39) sliding in the engaging recess (43) while rolling in the engaging recess (43) in a contact state.
