PURPOSE: To join easily and surely a cylindrical member perpendicularly to a plane member or a cylindrical member by pressing the vicinity of a joining part at one side locally from the axial direction and deforming plastically a rugged part formed at said side.
CONSTITUTION: Both of the 1st and 2nd members 1 and 2 are arranged by fitting the bottom part of member 1 to the recessed part of member 2. A die 3 descends while sliding on the outer periphery of member 1 to concentratively press the upper surface of the vicinity of the inner periphery of member 2 by its male teeth 3A. Then the member 2, made of soft material, flows plastically and perpendicularly to the spaces caused by a rugged part 1B. That is, the small projecting parts provided to the hard material gnaw into the soft material, and the soft material deformed plastically and locally by the projecting parts is joined to the hard material by a highly tightening force caused by an elastic stress generated at said part. Thus, the joining is completed by removing the die 3 thereafter.
