Slave driving force-transmitting mechanism for vehicle

摘要

Tri-port joints (56a, 56b), each of which includes revolvable rollers (70) to be directly fitted to outer circumferential surfaces of spider shafts (76a, 76b, 76c), are provided respectively at both ends of an input-side shaft (54) to which slave driving force is transmitted. Accordingly, it is possible to prevent a slave driving system from transmission of unnecessary torque, and obtain a slave driving force-transmitting mechanism (52) which is compact and light in weight, having a structure simplified as compared with those of the conventional technique.
