Claims

[Scope of utility model registration request]

In a transmission in which a reverse idler gear is moved in an axial direction to mesh with a reverse drive gear on an input shaft driven by an engine to achieve a reverse gear shift, a friction material is applied to the reverse idler gear. The rotating member having the friction material is integrally attached in the rotation direction, and the rotating member having the friction material is connected to the reverse drive gear before the friction material is shifted from the reverse idler gear in the axial direction and meshes with the reverse drive gear. Or, the horizontal plate is arranged so as to come into frictional contact with a member that rotates integrally with the reverse drive gear, and the friction material is placed in frictional contact with the reverse strike gear or a member that rotates integrally with the reverse drive gear during reverse shifting. Let me,
A reverse gear noise prevention device for a transmission characterized by reducing the rotation of a reverse drive gear and the relative rotation between a reverse idler gear and a reverse drive gear to prevent gear noise when engaged.
