摘要

PROBLEM TO BE SOLVED: To provide a fitting structure of a coil spring having excellent assemblability, and hardly removing a coil spring to axial force.SOLUTION: A fitting structure of a coil spring includes: a case 30; an operation shaft 40 fitted to the case 30 in a tiltable manner, and having a shank 41 projecting from the case 30; and a coil spring 110 having a one-side end part 110A in a wiring, and wound in a non-contact manner with a clearance. By engaging the wiring 111A wound in a non-contact manner to a spiral-like spring fitting groove 43 formed on the outer peripheral surface of the shank 41, the coil spring 110 is fixed to the shank 41 of the operation shaft 40.SELECTED DRAWING: Figure 2
