Claims

[Scope of Utility Model Registration Claim] When the hub sleeve is slid toward the spline teeth of the spline piece that is integrally connected to the transmission gear due to a shift operation of a manual transmission,
The inner spline tooth chamfer of the hub sleeve presses the spline tooth chamfer of the synchronizer ring in the axial direction, thereby synchronizing the rotation of the input system and output system of the transmission. In the apparatus, a portion of the spline tooth of the spline piece near the tooth tip of the chamfer is formed with a protrusion that protrudes toward the synchronizer ring, and a portion of the spline tooth of the synchronizer ring that faces the protrusion. A rotation synchronizing device for a manual transmission, comprising: a sloped portion, the sloped portion being set at an angle of inclination away from the chamfer of the spline piece by a dimension substantially corresponding to the amount of projection of the projection.
