Claims

[Scope of utility model registration request]

A coupling sleeve provided so as to be movable in the axial direction on the outer periphery of a synchro hub that rotates integrally with the shaft, a clutch gear disposed facing each other so as to be able to mesh with each other in the direction of movement of the coupling sleeve, and the clutch gear and the coupling sleeve. An outer ring which is disposed between and is pressed and moved with the initial movement of the coupling sleeve, an inner ring which is disposed concentrically with the outer ring, and an inner ring that is interposed between the outer ring and the inner ring so as to be frictionally engaged with both rings. What is claimed is: 1. A synchronizing device for a gear transmission, comprising: a friction ring that is locked to the clutch gear in a rotational direction; the friction ring is divided in a circumferential direction;
