供することにある。In the above technique, the wheel hub 9, the bearing 15, the front axle 14, the front fork 6, and the support stay 2 are provided between the sensor ring 23 and the sensor 26.
7, Because the above-mentioned six parts of the collar intervene,
The difference between the actual size of each part and the median dimensional tolerance accumulates, making it impossible to keep the distance between the tooth portion 24 of the sensor ring 23 and the sensor 26 within a predetermined range. That is, the tooth part 24 and the sensor 26 are too close to each other and interfere with each other, or the tooth part 2
It is conceivable that the distance between the sensor 4 and the sensor 26 is too large and the output signal from the sensor 26 becomes small. Therefore, an object of the present invention is to provide a wheel speed detecting device capable of keeping a distance between a ring and a sensor within a predetermined range when assembled.
