Abstract:
In the present invention: a pin member (11) is furthermore brought into contact with a contact surface in a state in which a shoulder member (12) is in contact with the contact surface; and each of a pin movement amount that is the distance from the initial position of the pin member (11) to the contact surface, and a shoulder displacement amount that is the amount of displacement when the shoulder member (12) retreats in association with contact by the pin member (11), is specified. When both of a first condition and a second condition are specified, the first condition being that the pin movement amount is included in a first range and the second condition being that the shoulder displacement amount is included in a second range, the pin member (11) is caused to retreat from the contact surface by a predetermined return amount, and furthermore, origin-point alignment of the pin member (11) and the shoulder member (12) is carried out with reference to the positions of the two members in the resultant state.
