摘要： A shaft member (1) and an outer periphery member (2) disposed on the outer periphery of the shaft member (1) are joined together by a spline (3) where a tooth (31) on the shaft member (1) and a tooth (32) on the outer periphery member (2) are fitted together. On one axial end side of the spline (3), the trough (31a) of the tooth (31) of the shaft member (1) is diametrically increased to form a diameter-increased region (S1), and provided in this diameter-increased region (S1) is a fitting portion (F) for the tooth (31) of the shaft member (1) and the tooth (32) of the outer periphery member (2).
