Claims

[Scope of utility model registration request]

The inner spline of the sleeve is engaged with the hub outer spline of the clutch hub fixed to the rotating shaft.
In a synchronizing meshing device for a gear transmission in which the sleeve is moved to engage the inner spline with a gear side spline of a synchronized side gear via a ring side spline of a synchronizer ring, the synchronizer ring is connected to the clutch hub and the synchronizer ring. an engagement mechanism that allows a predetermined amount of rotation in the circumferential direction of the synchronizer ring; an engagement groove is provided in the circumferential direction of the outer peripheral surface of the synchronizer ring; and a synchronizer spring that applies elastic force to the inner peripheral surface of the sleeve is connected to the engagement mechanism. A synchronous meshing device for a gear transmission, characterized in that it is provided in engagement with a matching groove.
