置。[Claims for Utility Model Registration] (1) A balk ring with a groove formed on one end and a friction surface on the other end can be slid in the axial direction so that the friction surface faces the spline piece of the reverse gear. A reverse gear noise prevention mechanism for a transmission, characterized in that the groove is provided with a leg portion of an insert key spline-fitted to the inner periphery of a sleeve of a synchronizer. (2) Prevention of reverse gear noise in a transmission according to claim 1, wherein the friction surface is integrally formed with a friction layer containing at least one of glass fibers, metal fibers, or metal compounds. Device.
