Embodiment Construction

[0037] Embodiments of the present invention will be described below with reference to the drawings. figure 1 It is a plan view showing the magnet mounting structure of the embodiment of the present invention. Grooves 14 are formed on the side surface of the top 12 of the knob component 10 for easy screwing with fingers. A protruding portion 22 is provided on the internal thread member 20 to pinch the knob member 10 and prevent it from coming out of the spoke 30 . The length direction of the internal thread points to the direction connecting the two protrusions 22 . The direction perpendicular to the length direction is the width direction of the internal thread member, and the width W is smaller than the diameter of the top 12 of the knob member. Therefore, the outer peripheral surface of the top portion 12 of the knob member is located at the outermost position, so that the knob member can be easily rotated by fingers.

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.

Description

technical field [0001] The present invention relates to a magnet installation structure, and more particularly relates to a magnet installation structure for installing a sensor capable of inductively detecting the running speed of a two-wheeled vehicle. Background technique [0002] In order to detect the traveling speed and the traveling distance of the bicycle conveniently, for example, a speedometer can be added on the bicycle. Figure 5 It is an external view of a bicycle equipped with a speedometer, Figure 6 yes Figure 5 A magnified view of the X section. The signal generating part and the sending part are composed of a sending device 128 movably arranged on the front fork 134 of the bicycle 124 and a magnet 113 movably arranged on the front wheel spoke 130 . Magnet 113 is installed on the position away from axle 136 with corresponding distance A between front wheel axle 136 and transmitter 128 as far as possible. [0003] With the above configuration, when the mag...
