A spoke 15 has a spoke crest 15a, a spoke radially outer wall 15b and a pair of spoke circumferential side walls 15c. In a cross section of the spoke 15 along a radial direction of a disk, a crest outer curved portion 15a2 of the spoke crest 15a is curved at a larger curvature than curvatures of a crest inner curved portion 15a1 of the spoke crest 15, a crest main portion 15a4 of the crest and the spoke radially outer wall 15b. Thus, compared with a conventional one, a configuration of the spoke 15 becomes like a box. As a result, a bending strength and a bending rigidity of the spoke 15 in the radial direction of the disk can be improved.
