Claims

[Claims for Utility Model Registration] (1) A housing attached to a wheel hub, and an operation knob that is rotatably fitted into the housing and has a boss portion formed with a cam surface that is displaced by the rotation. , an interlocking member having an engaging portion that engages with the cam surface and moving axially on the cam surface in conjunction with rotation of the operating knob; and an interlocking member fixed on the outer periphery of the tip end of the drive shaft in the housing a drive gear, which is attached to the inner circumferential surface of the housing so as to be axially movable and moves axially with the axial movement of the interlocking member to engage the drive gear and the clutch;
What is claimed is: 1. A hub clutch having a slide gear that is not coupled to the hub clutch, characterized in that a magnetic force generating section is disposed at an axial end of the cam surface and is attracted to the engaging section. (2) The hub clutch according to claim 1, wherein the magnetic force generator is a permanent magnet. (3) Claim 2, wherein the magnetic force generating object is an electromagnet.
Hub clutch as described.
