置決め装置。 A torsion spring is arranged inside an arm that has a fulcrum part with a U-shape on one side, and a through hole provided in the U-shaped fulcrum part and a coil part of the torsion spring are fitted into a common support shaft. In such a device, when the diameter of the through hole is l, the distance from the center of the through hole to the inner wall of the U-shaped fulcrum part is L, the inner diameter of the coil is D, and the wire diameter of the coil is d, then The respective values were made to satisfy the relationship L≦D+d−1/2l, and the spindle was made to pass through the inside of the coil while pressing the coil against the side of the U-shaped fulcrum with fingers or the like. A spring positioning device characterized by:
