Abstract

In engaging (connecting) a dog clutch by operating a synchromesh mechanism, when there occurs an uplock at the time when a first pressing force is caused to act on a hub sleeve, tooth tips of spline teeth of the hub sleeve contact with tooth tips of spline teeth of a synchronizer ring, and these spline teeth cannot be engaged. However, when a second pressing force is caused to act on the hub sleeve, the uplock is easy to be released. In addition, when torque from an engine is caused to act on the hub sleeve, a displacement is caused to occur in a rotation direction between the mutually contacting spline teeth. Thus, the uplock is reliably released.
