The invention provides a shift device which can maintain a gap of a sliding part between a shift fork and a sleeve and can reduce inclination of the sleeve relative to the shift fork. An engagement groove (17) is formed in the outer peripheral portion of the shift sleeve (4) over the entire circumferential direction, a cutout portion (21) is provided in a portion of the groove bottom of the engagement groove (17), the first diameter (D1) of the groove bottom of the cutout portion (21) is smaller than the second diameter (D2) of the groove bottom of the portion other than the cutout portion, and the shift fork (9) has an arc-shaped portion (16) covering the outer peripheral side of the groove bottom. The opening angle of a line connecting both end portions in the circumferential direction of the arc-shaped portion (16) and the center of the arc is larger than 180 degrees, the both end portions are respectively provided with claw portions (18) engaged with the engagement grooves (17), and the distance between the claw portions is larger than the first diameter (D1) and smaller than the second diameter (D2).

    本发明提供一种换挡装置,其能够维持换挡拨叉与套筒之间的滑动部分的间隙,并且能够降低套筒相对于换挡拨叉的倾斜。在换挡套筒(4)的外周部,遍及圆周方向上的整体地形成有卡合槽(17),在卡合槽(17)的槽底的一部分设置有切口部(21),切口部(21)的槽底的第1直径(D1)小于切口部以外的部分的槽底的第2直径(D2),换挡拨叉(9)具有覆盖槽底的外周侧的圆弧状部(16),圆弧状部(16)的连结圆周方向上的两端部与圆弧的中心的线的打开角度大于180°,在两端部分别设置有与卡合槽(17)卡合的爪部(18),爪部彼此的距离大于第1直径(D1),小于第2直径(D2)。
