ド４に、位置決めボール１２が弾圧されて択一的
に係合する軸方向複数本の周溝１１が形成されて
おり、この周溝１１は軸方向断面形状がボール１
２の外面の曲率に略等しい曲率の円弧Ｄとなつた
位置決定溝部１４と、この位置決定溝部１４の端
部からシフトロツド移動時にボール１２が乗上げ
るテーパ面部１５とが形成されている変速用シフ
トロツドの位置決め機構において、 前記位置決定溝部１４とテーパ面部１５との間
に角部１７を形成すべく、シフトロツド４の軸線
１６に対する位置決定溝部１４の端部における円
弧Ｄの接線の傾斜角度Ｆよりもテーパ面部１５の
傾斜角度Ｅが小さく設定されていることを特徴と
する変速用シフトロツドの位置決め機構。[Claims for Utility Model Registration] A plurality of circumferential grooves 11 in the axial direction are formed in the shift rod 4, which is moved in the axial direction by a speed change operation, with which positioning balls 12 are selectively engaged by being pressed, This circumferential groove 11 has an axial cross-sectional shape of a ball 1.
2, and a tapered surface portion 15 on which the ball 12 rides from the end of the positioning groove portion 14 when the shift rod moves. In this positioning mechanism, in order to form a corner 17 between the positioning groove 14 and the tapered surface 15, the inclination angle F of the tangent to the arc D at the end of the positioning groove 14 with respect to the axis 16 of the shift rod 4 is A positioning mechanism for a gear shift rod, characterized in that an inclination angle E of a tapered surface portion 15 is set small.
