PROBLEM TO BE SOLVED: To provide a synchronization device capable of suppressing occurrence of collision noise without increasing the number of components, capable of reducing both of the manufacturing cost and assembly man-hours, and capable of improving merchantability.SOLUTION: A synchronization device includes a hub 10, a sleeve, a blocking ring and a synchronizing spring. A cutout groove 12 is formed on an end of the hub 10 on the blocking ring side, the synchronizing spring has a circular-arc-shaped base part and an abutment part 42 abutted to an outer peripheral surface of the blocking ring integrally, and the abutment part 42 has two fitting parts 42a respectively fitted to two wall parts 12a of the cutout groove 12 of the hub 10 and a continuation part 42b integrally. The blocking ring has a regulating part 33a for regulating relative rotation within a prescribed range by being abutted to the two fitting parts 42a of the synchronizing ring when being relatively rotated with respect to the hub 10. |
