Abstract
To provide device capable of enhancing the detection accuracy of a wheel speed detecting device and reducing cost. A wheel speed detecting device for a rear wheel includes a pulsar ring mounted on a rear wheel hub, and a pulse counting sensor mounted on a swing arm. The pulsar ring includes a disc, and pulse detecting holes are formed at a predetermined pitch on a pitch circle drawn at a radially inward circumferential position spaced at a predetermined distance from the outer edge of the disc. The pulse detecting hole is formed in a position on the center side apart from the outer edge of the pulsar ring, leaving the outer edge of the pulsar ring in a circular form. Therefore, it is possible to prevent warpage of the pulsar ring by the outer edge portion if the pulse detecting holes are made by pressing.
