When press-fitting the press-fitting part P into the large-diameter hole w1 after centering the hole w1 , even if the press-fitting jig main body 3 moves further with the centering member 6 expanded, the centering member 6 will not move. It will not be locked against the stepped part of the hole. Furthermore, before the press-fitting part P is press-fitted into the large-diameter hole w1, the centering member is expanded to center the press-fitting jig main body 3 with respect to the large-diameter hole w1 , and the press-fitting part P is inserted into the large-diameter hole w1.
When the centering member 6 is partially press-fitted into w 1
Since the centering member 6 is contracted and closed, it does not interfere with the stepped portion of the stepped hole when the centering member 6 is contracted and closed.
