PROBLEM TO BE SOLVED: To provide a member for machine element obtained as a complete member by forming the member having a part of the structure of the machine element by normal extrusion dies and welding the formed members with each other, and to provide the manufacturing method therefor. SOLUTION: This member 2 having a part of the structure of the machine element and realizing one machine element by combining the plural members, is subjected to friction welding along a weld line 3 occurred by butting the plural members each other. Since the member 1 for the machine element, is divided into the member 2 of a unit of bisection or over, which is easy to manufacture, the unit member 2 can be formed by the normal dies. Since the divided members 2 are welded by the friction welding with few warp, moreover, sufficient welding strength, both of function and facilitation property for manufacturing, can be cleared. |
