Abstract
A hydraulic type starting clutch having an input rotating member rotatable in unison with an input shaft, an output rotating member rotatable in unison with an output shaft, and friction plates interposed between the input and output rotating members and adapted to transmit torque from the input rotating member to the output rotating member when engaged. An urging member urges the friction plates to cause transmission of torque from the input rotating member to the output rotating member, and a hydraulic pressure chamber is defined between the urging member and the output rotating member and supplied with a hydraulic fluid from a hydraulic fluid source. A control device controls a pressure regulating valve in a manner such that the pressure in the hydraulic pressure chamber is regulated to values dependent upon the rotational speed of the input shaft.
