| 摘要 | The present invention includes a spiral forming step causing a substantially liner elongated member, which is conveyed toward one side in a longitudinal direction of the elongated member by a pair of conveying rollers, to be engaged at one side in a second direction with a pressing member movable in the second direction so that a spiral body including the fixed coil part, the first movable coil part and the second movable coil part is formed from the linear elongated member. The spiral forming step is configured to control the position of the pressing member with respect to the second direction, while recognizing, based on a signal from a rotational speed sensor for detecting the rotational speed of the conveying roller, a relationship between a position in the longitudinal direction of the elongated member that is engaged with the pressing member and the position in the circumferential direction after the spiral body is formed. | ||||||
