Abstract
An improvement is made to the shift fork which engages the circumferential groove of a clutch means slidable along an axial line of a main shaft. The shift fork is composed of a piece made of material having high wear resistibility and a main body whose end part is smaller in cross section than the circumferential groove of the clutch. The piece is in the shape of a channel section and has an elastic tongue-like projections projecting from the bottom of this channel section. The tongue projections are urged, as being fastenings, into grooves formed at the end parts of said main body, whereby the piece is tightly attached to the main body to thus form parts engaging said circumferential grooves of the clutch means.
