In the plurality of teeth (12), a base height Kt, which is the length in the radial direction of a base (15) of the wedge-shaped part (13), and a tip height Ks, which is the length in the radial direction of a circumferential direction tip (16) of the wedge-shaped part (13), satisfy the relationship of 1 < Kt/Ks ≤ 2.85.
