Claims

[Scope of utility model registration request]

Inside the casing, the rotary shafts are supported so as to be slidable in the axial direction, and are arranged in parallel with each rotating shaft on which a gear train for each gear is arranged, and can be selectively slid to the reverse gear side in the axial direction by operating a control lever. a forkshaft that moves; a shift fork that is integrally assembled on the forkshaft and selectively operates a synchronizer for reverse gear according to the sliding direction of the forkshaft; It is attached to the reverse gear side in the axial direction of the shift fork and is connected to the reverse shift arm, and when it moves from the neutral position to the reverse gear side, it slides the reverse gear sliding gear that engages with the shift arm and moves backward. This is a gear change operation device for a manual transmission that is equipped with a reverse shift head that engages with another gear for a gear, and the reverse shift head is installed on the fork shaft so as to be slidable in the axial direction, and the reverse shift head is also mounted on the fork shaft. The reverse shift head is positioned at a neutral position by a day tent mechanism provided between the fork shaft and the casing side member to maintain a predetermined distance from the shift fork in the axial direction, and the reverse shift head is provided between the fork shaft and the casing side member. The forkshaft is selectively fixed to the forkshaft and the casing side member by an interlock mechanism, and the interlock mechanism is configured to allow the forkshaft to slide a predetermined amount relative to the reverse shift head in the axial direction toward the reverse gear side when in the neutral state. 1. A gear shift operation device for a manual transmission, characterized in that a permitting means is provided.
