。 It fits into an annular groove provided on the outer periphery of a clutch hub sleeve that is assembled to a shift forkshaft and constitutes a synchronized mesh, and when the shift lever is operated, the clutch hub sleeve comes into contact with the side wall surface of the annular groove and moves the sleeve in the axial direction. In a shift fork of a sliding manual transmission, chamfers are formed at both circumferential ends of a contact surface facing the side wall surface of the sleeve of the shift fork, and chamfers on both sides of the contact surface. 1. A shift fork for a manual transmission, characterized in that an arc-shaped groove extending from an inner circumference to an outer circumference of the shift fork is formed in between.
