Supporting structure of wheel speed sensor

A supporting structure of a wheel speed sensor comprising:

• a bracket for supporting an axle of a wheel, the bracket including a sensor mounting section on an outer surface of the bracket,
• the wheel speed sensor for detecting a rotational speed of the wheel, the wheel speed sensor including:
• a fixing section fixed to the sensor mounting section, the fixing section having a seat surface extending in a direction that intersects with a direction of the axle and is in contact with the sensor mounting section, and
• a sensor section extending from the fixing section in the direction of the axle,
• wherein the fixing section and the sensor section are made of resin, and the fixing section is integrally formed with the sensor section;
• and
• a fastening member;
• contacting and fixing the seat surface of the fixing section to the sensor mounting section of the bracket,
• wherein the bracket further includes,
• a rotation regulating portion for regulating a rotation of the wheel speed sensor, the rotation regulating portion projecting from the outer surface of the bracket to be engaged with an outer circumferential portion of the fixing section, and
• a protection wall for covering at least a portion of an outer circumference of the sensor section via a clearance.
