Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/024557
Kind Code:
A1
Abstract:
Provided is a power transmission device in which it is possible to vary, as required, the torque when a back torque limiter cam is operating and the torque when a pressure-contact assisting cam is operating, and satisfactorily engage a clutch member and a pressure member with each other while causing the cam surface of the pressure-contact assisting cam and the cam surface of the back torque limiter cam to face each other and thus minimize rattling. The receiving part of a clutch spring (10) on the pressure-member (5) side comprises a receiving member (11) separate from the pressure member (5). A first cam surface (C1) and a second cam surface (C2) constituting the back torque limiter cam are respectively formed on the receiving member (11) and the clutch member (4), and a third cam surface (C3) and a fourth cam surface (C4) constituting the pressure-contact assisting cam are respectively formed on the pressure member (5) and the clutch member (4).
