Claims

[Scope of utility model registration request]

It is equipped with a synchronized mesh mechanism in which the hub sleeve is reshifted in the direction opposite to that during a forward shift during a reverse shift, and a cone body provided on the inner wall of the transmission case facing the direction of the hub sleeve's missed shift is equipped with a synchronized mesh mechanism. Against! ,
In a gear noise prevention device of the type in which a friction ring is pressed by air vibration resift of a brake sleeve, the cone body is formed separately from the transmission case, and the positioning hole portion formed in the cone body and the gear shift The cone body is positioned with respect to the transmission case by fitting with a positioning protrusion protruding from the inner wall of the machine case, and the cone body is fixed by a locking part provided on the transmission case side. Gear noise prevention device for manual transmissions.
