Abstract
There are provided a synchronizing system which synchronizes two relatively rotating rotary bodies with each other by frictional forces generated between friction discs, such that a larger torque can be transmitted between the rotary bodies as an input torque becomes larger, and a transmission torque control device for the synchronizing system. In order to transmit torque between an input shaft and a gear member, the synchronizing system which connects the input shaft and the gear member with each other while synchronizing them urges a blocking ring toward the gear member by using a synchronizing spring, when a sleeve is caused to slide toward the blocking ring by an actuator. This starts synchronization of the input shaft and the gear member via friction discs rotating together with the blocking ring and friction discs rotating together with the gear member, and brings the tooth ends of the splines of the sleeve and the tooth ends of the splines of the blocking ring into abutment with each other, whereby the input shaft and the gear member are mechanically connected to each other.
