Technology which enables a first member and a second member to be fastened together strongly is provided. A bar-shaped section is formed on the first member, a hole is formed in the second member, and the bar-shaped section of the first member is pressure fitted into the hole of the second member. Here, the diameter of the circumscribed circle which circumscribes the cross-section perpendicular to the axis of the bar-shaped section is made greater than the diameter of the inscribed circle which inscribes the cross-section perpendicular to the axle of the hole. The diameter of the inscribed circle which inscribes the cross-section perpendicular to the axis of the bar-shaped section is made smaller than the diameter of the circumscribed circle which circumscribes the cross-section perpendicular to the axle of the hole. A tapered section, in which the side face is inclined with respect to the axial direction, is formed in the side face of the harder of the bar-shaped section and the hole, in the end portion which is positioned to the forward side during pressure fitting.

Assembly member and method of manufacturing assembly member

Technology which enables a first member and a second member to be firmly fastened together is provided. A bar-shaped section is formed on the first member, a hole is formed in the second member, and the bar-shaped section of the first member is pressure fitted into the hole of the second member. Here, peak sections which extend intermittently in the axial direction or peak sections which extend obliquely with respect to the axial direction are formed in a repeating fashion in the circumferential direction, on the side face of the harder of the bar-shaped member and the hole.
