Claims

[Scope of utility model registration request]

Shift lever of a gear transmission - A shift supported on the shaft of a shift and select lever shaft that is supported in the housing so that the select operation can be performed by moving it in the axial direction, and the shift operation can be performed by rotating it around the axis. An inner lever, a collar disposed on the axis of the shift and select lever shaft on both sides of the boss portion of this lever, and a collar disposed between these collars and the inner wall surface of the housing, and a selector that is connected to the shift inner lever through the collar. In a shift and select control mechanism equipped with a return spring that applies a return force, dog clutch teeth that can engage with each other are formed at opposing ends of either one of the collars and the boss portion of the shift inner lever. Under normal conditions, the torsional force of the return spring applies rotational force to the collar in one direction to position the clutch teeth so that they do not engage with each other. A gear shift i characterized in that the gears are shaped so that they engage with each other when shifting to a forward speed in the opposite direction, and the collar having the clutch teeth is further provided with a stopper that prevents rotation in the reverse shift direction. Shift and select control mechanism.
