Patent ID: 8444164

Claim:
A wheel speed sensor mounting structure comprising: a fork for rotatably supporting a wheel; a brake disc mounted on a side surface of the wheel in an integrally rotatable manner wherein braking is applied by a brake caliper; and a wheel speed sensor for detecting a rotational speed of the wheel, said wheel speed sensor including a pulsar ring rotatable integrally with the wheel and a sensor body portion arranged close to an annular portion to be detected and formed on the pulsar ring for generating pulse signals corresponding to a rotational speed of the pulsar ring; said pulsar ring is mounted on a wheel side and the sensor body portion is mounted on a fork side; said pulsar ring includes pulsar ring mounting portions projecting in a radially outward direction from the portion to be detected; said pulsar ring mounting portion being fastened to the side surface of the wheel together with a brake disc mounting portion formed on the brake disc using a fastening member in a state wherein the pulsar ring mounting portion overlaps with the brake disc mounting portion; and a seat portion, fastened by the fastening member, and the portion to be detected of the pulsar ring mounting portion are arranged on the same plane.
