ABSTRACT:
A brake disk has a ring-shaped braking section with plural inner circumferential spokes, a hub section with plural outer circumferential spokes, a dish-shaped spring so placed on the same side surfaces of a pair of the plurality of spokes as to be in pressure contact commonly therewith, and a connecting pin used with the spring to connect the paired spokes and disposed to allow both of the paired spokes to move relatively slightly with respect to each other. One spoke is provided on a surface of its end portion thereof with a circumferential groove and the other paired spoke is provided on a surface of its end portion with a circumferential ridge. The ridge is loosely inserted in the groove when assembled. The dimension of the ridge is such that a small play exists in both the axial and radial directions when the ridge is inserted in the groove. Concave recesses are arranged in the end portions of the paired spokes in opposition, forming a hook for receiving a pin for restricting axial relative displacement of the hub and braking sections.
