The present invention provides a synchronization device for a manual transmission of a vehicle, including a synchronizer ring (24) configured to synchronize rotation of a transmission gear (12) and rotation of a clutch hub (21), the synchronizer ring (24) including: a ring body having an annular shape; an axial protruding portion, which protrudes from the ring body toward the clutch hub (21) in an axial direction so as to set a size of an axial clearance to be formed between the ring body and the clutch hub (21) in the axial direction; and a radial protruding portion, which protrudes from the ring body toward the clutch hub (21) in a radial direction intersecting the axial direction so as to set a size of a radial clearance to be formed between the ring body and the clutch hub (21) in the radial direction. The ring body, the axial protruding portion, and the radial protruding portion are formed integrally by metal stamping. With this, it is possible to provide an effective technology for reducing cost required to manufacture the synchronizer ring of the synchronization device for a manual transmission of a vehicle while securing appropriate clearances between the synchronizer ring and the clutch hub opposed to each other. |
