To provide a floating brake disc BD1 for a motor cycle equipped with a wheel speed sensor S that responds to magnetism, which can reduce its weight and can detect a wheel rotation speed with the wheel speed sensor S.SOLUTION: A floating brake disc comprises an annular rotor 1, a hub 2 arranged inside the rotor 1, and a plurality of connection members 3 that connect the rotor 1 and the hub 2 in a floating state. In a predetermined annular region 25 of the hub 2 positioned radially inward with respect to the connection member 3, a large number of detection units 4 for generating pulses to a wheel speed sensor S are provided at regular intervals in a circumferential direction. The hub 2 is made of a non-magnetic material, and each detection unit 4 is composed of a magnetic film 5 formed on the surface of the hub 2.SELECTED DRAWING: Figure 1

    【課題】磁気に反応する車輪速センサSを具備する自動二輪車用のフローティング型ブレーキディスクBD1であって、その重量を軽量化でき、かつ、車輪速センサSにより車輪回転速度を検出可能なものを提供すること。【解決手段】環状のロータ1と、ロータ1の内側に配置されるハブ2と、ロータ1とハブ2とをフローティング状態に連結する複数の連結部材3とを備え、連結部材3よりも径方向内側に位置するハブ2の所定の環状領域25に、車輪速センサSにパルスを発生させる検出部4が周方向に等間隔で多数設けられる。ハブ2が非磁性体材料で形成されると共に、各検出部4は、ハブ2の表面に形成された磁性膜5で構成される。【選択図】図1
