Claims

[Scope of utility model registration request]

A shift inner lever is assembled on the shaft of the shift and select lever shaft so that a select operation can be performed by moving in the axial direction, and a shift operation can be performed by rotating around the shaft, and the shift inner lever is installed parallel to the shift and select lever shaft. Reversing lever shaft installed in the. }On the other hand, it is assembled so that it can be shifted in the direction around its axis, and when the shift inner lever is operated to a predetermined selection position, the engaging pawl of this lenna lever reverses and transmits the shift operation. In a gear transmission equipped with a shift reversing lever that can be engaged with the shift reversing lever, a holder that is constantly engaged with the engaging pawl of the shift inner lever is placed on the axis of the reversing lever shift. - It is assembled so that it can be rotated in the same direction as the shift operation direction of the shift reversal lever in conjunction with the movement, and a cam surface is formed on one of the opposing parts of the holder and the shift reversal lever.
On the other hand, a cam follower is provided which is pressed against the cam surface by a certain spring force, and the shift inner lever and the holder interlocked with the cam follower are connected to each other in a neutral position with respect to each shift direction. 1. An abnormal noise prevention device for a gear transmission, characterized in that the operating force in the shift l direction is exerted on each lever only when the lever is in the position.
