ABSTRACT:
A synchronizer ring and a manufacturing method thereof having an object to reduce the manufacturing cost and to improve its durability. Therefore, the synchronizer ring according to the invention includes a coating formed by thermal spraying of wear-resistant material on a conical surface of the synchronizer ring body which has been subjected to mechanical machining, pressing a conical jig having a predetermined opening angle against the coated surface in a manner to exert a surface pressure of 4 to 40 N/mm.sup.2 on the coated surface, and rotating the conical jig in a range of 45 to 590 degrees, to thereby make the heights of projections of the surface of the coating uniform.
