Claims

[Claims for Utility Model Registration] When the hub sleeve attached to the outer periphery of the clutch hub with splines is slid by a shift operation, the chamfer of the inner spline teeth of this hub sleeve slides into contact with the outer spline teeth of the synchronizer ring. In a rotation synchronizing device for a transmission, in which rotation synchronization between an input system and an output system of a transmission is achieved by pressing a channel of the hub sleeve, the groove formed between the internal spline teeth of the hub sleeve; a protrusion formed on the synchronizer ring and engaged in a state that allows the hub sleeve to slide relative to the groove; and a projection between the inner spline teeth of the hub sleeve and the synchronizer ring during rotational synchronization between the groove and the protrusion. A rotational synchronizer for a transmission, comprising: a clearance for determining the position of a mutual chamfer with respect to a direction of rotation with an external spline tooth;
