Claims

[Claims for Utility Model Registration] The gear lever slides from the neutral position to one of the highest speed shift positions and the other reverse shift position in conjunction with the shift operation of the change lever from the neutral range N to the highest speed position V and reverse position R. fork shaft 49
₃ is supported in the transmission case 24, and the fork shaft 49 ₃ and the transmission M are slidably supported on the shaft.
The fork shaft ₄₉₃ is in a neutral position between the highest speed shift fork 56 for controlling the highest speed gear train _G5 and a fixed member fixed to the transmission case 24 and protruding from its inner wall. and the highest speed shift position, the fork shaft ₄₉₃ and the fixed member are disengaged, and the fork shaft ₄₉₃ and the highest speed shift fork 56 are connected, and the fork shaft ₄₉₃ is moved between the neutral position and the reverse shift position. In the transmission change mechanism, the transmission change mechanism is provided with an alternate coupling device 74 that disengages the fork shaft ₄₉₃ and the highest speed shift fork 56 when moving between them, and connects the highest speed shift fork 56 and the fixed member. Another shift fork 54 for controlling another gear train G ₃ , G ₄ of the transmission case 24
The transmission is fixed to another fork shaft ₄₉₂ which is slidably supported by a bearing sleeve 53 fixed to the transmission case 24, and the bearing sleeve 53 is made to protrude from the inner wall of the transmission case 24 to serve as the fixing member. Machine change mechanism.
