To provide a ventilated type brake disk that can restrain thermal strain from occurring when heat is transferred to support parts via disks.SOLUTION: A ventilated type brake disk comprises two disks 1 each consisting of an annular member of which a center is opened, and facing each other, and a body 2 comprising a central part 3 attachable to an axle of a vehicle, and a plurality of support part 4 radially extended toward a radial direction from the central part 3, and supporting the two disks 1 while separating them by a predetermined dimension. The central part 3 and the plurality of support parts 4 are formed separately from each other, and the support parts 4 are fitted into attachment opening parts 3c formed in the central part 3 respectively.SELECTED DRAWING: Figure 1

    【課題】ディスクを介して支持部に熱が伝達された際、熱歪みが生じるのを抑制することができるベンチレーテッド型ブレーキディスクを提供する。【解決手段】中央が開口した円環状部材から成り、互いに対峙した2枚のディスク1と、車両の車軸に取付可能な中央部3、及び中央部3から径方向に向かって放射状に複数延設され、2枚のディスク1を所定寸法離間させつつ支持する支持部4を有した本体2とを具備したベンチレーテッド型ブレーキディスクにおいて、中央部3及び複数の支持部4がそれぞれ別体とされるとともに、中央部3に形成された取付用開口部3cに支持部4がそれぞれ嵌合されて成るものである。【選択図】図1
