Claims

[Claims for Utility Model Registration] An axle is inserted between an elongated hole in the longitudinal direction provided at the rear end of the rear fork, and the end of the axle is connected to a movable support member provided outside the elongated hole. The movable support member can be moved in the front-rear direction by screwing an adjuster bolt through the retainer attachment hole provided at the rear end of the rear fork into a female thread formed at the rear of the support member so as to be rotatable while restricting movement in the axial direction. In a chain adjuster for a motorcycle, etc., which is configured to be movable, the rear end portion of the rear fork is formed with an axle bracket having a U-shaped cross section with an open outer side, and a U-shaped vertical wall of the axle bracket is formed. A chain adjuster for a motorcycle or the like, characterized in that the elongated hole is formed and a wall surface is formed at the rear end, and the wall surface is used as the retainer.
