Abstract

A magnet mounting structure for fastening a magnet to a spoke of a two-wheeled vehicle even without tool includes a knob member having a screw and the magnet and an internal thread member in which the screw is screwed. The spoke is held between the knob member and the internal thread member to allow the magnet to be fastened to the spoke.

Claims

1. A magnet mounting structure for fastening a magnet sensed by a sensor to a spoke of a wheel, comprising:

a knob member having a screw and containing the magnet; and

an internal thread member with said screw screwed therein,

said spoke held between said knob member and said internal thread member to fasten said magnet to said spoke.

2. The magnet mounting structure according to claim 1, wherein

said magnet is housed in a head portion of said knob member.

3. The magnet mounting structure according to claim 1, wherein

said internal thread member has a surface opposite to said knob member and provided with an elastic layer.

4. The magnet mounting structure according to claim 1, wherein

said internal thread member has a semicylindrical groove for receiving a round spoke.

5. The magnet mounting structure according to claim 1, wherein

said internal thread member has a flat portion for receiving a flat spoke.

6. The magnet mounting structure according to claim 1, wherein

said knob member has a flat bottom surface with said screw projecting therefrom.

7. The magnet mounting structure according to claim 1, wherein

said head portion of said knob member has a grooved lateral periphery.

8. The magnet mounting structure according to claim 1, wherein

said internal thread member has projections on opposite sides thereof for preventing the spoke from departing therefrom.

9. The magnet mounting structure according to claim 1, wherein

said internal thread member has its width smaller than the diameter of said knob member.

10. The magnet mounting structure according to claim 1, wherein

said internal thread member is formed of organic resin.
