Claims

[Scope of utility model registration request]

, a sleeve that is axially movable and has an internal spline that engages with the external spline of the clutch hub, a synchronizer ring that has an external spline that engages after being in contact with the internal spline of the sleeve, and the external spline of the synchronizer ring is in contact with the internal spline of the sleeve. In a synchronizer for a transmission that includes a driven gear that has an outer spline that meshes with an inner spline in the sleeve after meshing and makes frictional contact with a synchronizer ring during synchronization, a first chamfer portion that intersects at a large angle for synchronization is axially An in-sleeve spline is constituted by a first tooth group at the end and a second tooth group at the axial end, which intersects at a small angle for meshing and has a second chamfer section. protrudes in the axial direction, the teeth facing the second tooth group of the synchronizer ring outer spline are missing, and the third chamfer part intersects with the synchronizer ring outer spline at a large angle for synchronization with the first chamfer part. The fourth chamfer part is provided so as to be in contact only with the driven gear outer spline and intersect with the driven gear outer spline at a small angle for meshing. A synchronizing device for a transmission, characterized in that it is provided with a synchronizing device for a transmission.
