摘要： PROBLEM TO BE SOLVED: To provide a spiral spring capable of reducing the maximum value of stress, and reducing a variation in a stress distribution.SOLUTION: A spiral spring 1 can be elastically deformed from a minimally-deformed state to a maximally-deformed state. In the maximally-deformed state, the spiral spring has a non-contact section in which at least part of portions of a spring material S which are radially adjacent to each other are not in contact with each other, and a contact section C in which all portions of the spring material S which are radially adjacent to each other are in contact with each other. In the maximally-deformed state, when a line which connects the center O of the spiral shape of a spiral section 21 and an outer contact section B where an outer end 22 and an outer mate object 4 are in contact with each other is referred to as a reference line L, an inner reference section (A) is disposed at the radial inside of the spiral section 21 in a zone having center angles of 80° to 160° with the center O of the spiral shape as a center along a direction in which the spiral section 21 extends. The contact section C is disposed at the radial outside of the inner reference section (A).

摘要： PROBLEM TO BE SOLVED: To provide a spiral spring to be mounted in an inside mounting portion having a rectangular cross section, while ensuring linear spring characteristics in a wider angle range than before.SOLUTION: This spiral spring includes a locking portion having a shape corresponding to three planes (32, 36, 40) of four planes constituting an outer peripheral surface of the inside mounting portion 30. The locking portion includes: a first locking portion 14 having a shape corresponding to the first plane 32 of the inside mounting portion 30; a second locking portion 18 having a shape corresponding to the second plane 36 adjacent to the first plane 32 of the inside mounting portion 30; and a third locking portion 22 having a shape corresponding to the third plane 40 adjacent to the second plane 36 of the inside mounting portion 30. When the inside mounting portion 30 is viewed in the axial direction, with the spiral spring mounted in the inside mounting portion 30, a distal end 14a of the first locking portion 14 is located between an intermediate position C of the first plane 32 and an end portion D on the fourth plane side.

摘要： PROBLEM TO BE SOLVED: To provide a spiral spring which can prevent degradation in slidability between spring wires over an extended time period.SOLUTION: The spiral spring 2 is a spiral spring 2 which is formed by molding a belt-shaped spring wire 10 in a spiral shape, and hitting marks 16 are formed on the entire surface of at least the outer surface of the belt-shaped spring wire 10. Then a lubricating film 18 is formed at least on the outer surface where the hitting marks 16 are formed. Thereby, the adhesion between the spring wire 10 and the lubricating film 18 is improved, and the lubricating film 18 can be prevented from exfoliating from the spring wire 10. Thus, slidability can be maintained over an extended time period.
