PURPOSE:To secure a press-fit margin in the tooth thickness direction so as to prevent play in the rotating direction, and reduce a press-fit load in the case where an outer spline of a male member is press-fitted to an inner spline of a female member. CONSTITUTION:A tooth thickness at both ends 3a, 3b in the tooth direction of an outer spline 3 is increased go that a press-fit margin alpha in the tooth thickness direction is secured at both ends 3a, 3b between the outer spline 3 and an inner spline 4. Consequently, a press-fit load can be reduced since a press-fit portion is limited to both ends 3a, 3b. |
