PROBLEM TO BE SOLVED: To provide an erroneous operation preventing mechanism for preventing a shift to a transmission stage when a clutch pedal is not operated and in turn allowing a free motion from a speed change stage position of a shift lever to a neutral position thereof.SOLUTION: There are provided: a male side member 24 having a tapered part 20a and returning back to an initial position in response to a returning operation after it is moved from the initial position before a treading operation of a clutch pedal; a female side member 26 having a second taper part 26a capable of sliding the same and movable in response to a motion of the male side member; and an engaging part 30 connected to a shift fork 20, immovably engaging the shift fork at a first engaging position 30a with the female side member when the shift fork is placed at a neutral position and the male side member is placed at the initial position, releasing the engagement when it is moved from the initial position and movably engaging the shift fork at a second engaging position 30b when the shift fork is returned back to the initial position in response to a returning operation after the shift fork is moved to a transmission stage position.SELECTED DRAWING: Figure 1
【課題】クラッチペダルの操作がないときの変速段へのシフトを防止する一方、シフトレバーの変速段位置からニュートラル位置への自由な移動を許容する誤操作防止機構を提供する。【解決手段】テーパ部20aが形成され、クラッチペダル踏み込み操作前の初期位置から移動した後、戻し操作に応じて初期位置に復帰する雄側部材24と、それをスライド可能な第2のテーパ部26aが形成されて雄側部材の移動に応じて移動可能な雌側部材26と、シフトフォーク20に連結され、それがニュートラル位置にあって雄側部材が初期位置にあるとき、雌側部材と第1係合位置30aでシフトフォークを移動不能に係合し、初期位置から移動するとき係合を解除し、シフトフォークが変速段位置に移動した後に戻し操作に応じて初期位置に復帰するとき、第2係合位置30bでシフトフォークを移動可能に係合する係合部30を備える。【選択図】図1
