## Abstract

A front wheel caliper bracket for supporting an axle is provided in a lower end portion of a front fork. A wheel speed sensor is mounted on the bracket. The wheel speed sensor includes a fixing section and a sensor section, and is mounted on a sensor mounting section of the bracket by a bolt. The sensor mounting section is integrally formed with a rotation regulating portion in a projecting fashion. When fastened by the bolt, a lateral part of the rotating wheel speed sensor comes into contact with the rotation regulating portion to regulate the rotation of the wheel speed sensor, so that the stress from the rotation regulating portion is not exerted directly on the sensor section.

## Claims
