PURPOSE:To prevent the wear of a shift fork by fitting a pair of semi-circular ring members made of antiwear plastics into a fork groove formed on the outer peripheral surface of a coupling sleeve. CONSTITUTION:Semi-circular members 18 and 18' are semi-circular ring members having an outer diameter dimension corresponding to the diameter, width and depth of a fork groove 14 formed on the outer peripheral surface of the coupling sleeve 6. Each of the members 18 and 18' has a U-shaped section opened outwardly. At both ends of each of the members 18 and 18', are formed engaging claws 19 and 20 having mutually opposed hook shapes. Engaging claws 19 and 20 of one semi-circular ring member 18 are engaged with opposed engaging claws 20 and 19 formed in another semi-circular ring member 18' to thereby form a ring unit. |
