    Patent number: 9709131
    Abstract: When a reverse select operation is performed, a pre-balk lever (180) rotates to a rotation position as a control rod (100) rotates. The pre-balk lever (180) has an engagement portion (190), which engages with a tip end portion of a pre-balk pin (162) at the rotation position. As a reverse lever (136) swings while they are engaged with each other, a shift rod (113) moves in such a direction as to activate a synchronizer (60). The engagement portion (190) has a guide surface (192), which guides the tip end portion of the pre-balk pin (162) to the engagement position while the pre-balk lever (180) is rotating toward the rotation position.
