A pulsar ring (20) includes a portion to be detected (21) and a pulsar ring mounting portions (23) which project in the radially outward direction from an outer peripheral portion of the portion to be detected (21). The portion to be detected (21) and a pulsar ring mounting portion (23) are arranged so as to form continuous planar surfaces, and the pulsar ring (20) is rigidly mounted on a mounting boss (50) of a wheel (1b) using a bolt (10) by fastening a brake disc (4) and the pulsar ring (20) together in a state where the pulsar ring (20) overlaps with the brake disc mounting portion (4b). Even when the brake disc (4) thermally deforms at the time of braking so that the pulsar ring mounting portion (23) is pulled radially outwardly, the portion to be detected (21) and the pulsar ring mounting portion (23) are arranged on the same plane thus forming the continuous planar surfaces and hence, the portion to be detected (21) is hardly twisted and thereby the deformation of the portion to be detected (21) is hardly generated as a whole.
