PURPOSE: To eliminate a high load and damage to a meshing spline end part, the complicated constitution of a movable cam assembly and damage to a basket member end part connecting mechanism to a foot part. CONSTITUTION: In a hub lock for selectively locking a wheel hub 10 rotatable to a driving shaft 12, the driving shaft 12, a clutch ring 40 and the wheel hub 10 are coaxially installed on a shaft in the clutch ring 40, and the clutch ring 40 is housed in the wheel hub 10. The clutch ring 40 permanently meshes with the wheel hub 10, and the peripheral spline meshes with an inside spline of the wheel hub 10. The clutch ring 40 moves in the axial direction in the wheel hub 10, and both splines of the clutch ring 40 and the wheel hub 10 are meshed over the movement limit. A shift mechanism governs the connection or a release of the hub and the shaft by meshing/releasing the clutch ring 40 with/from the shaft 12. |
