A wheel hub, a pulsar ring, and a magnetic sensor are provided. The wheel hub supports an axle. A brake disc is secured to the wheel hub. The pulsar ring is secured to the wheel hub. The magnetic sensor is configured to detect a passing of a pulsar hole disposed on the pulsar ring. The wheel hub forms a cylindrical outer peripheral surface as an outer peripheral side spigot portion. The brake disc includes a disc-side spigot portion in contact with the cylindrical outer peripheral surface. The pulsar ring includes a ring-side spigot portion in contact with the cylindrical outer peripheral surface. The brake disc and the pulsar ring are co-clamped and secured to a hub-side flange formed at the wheel hub.
