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 an alloy wire for heat resistant spring which can stably exert sag resistance even under high temperature environments exceeding e.g. 700°C and also to provide a heat resistant coil spring for high temperature environments using the same. SOLUTION: The alloy wire for heat resistant spring is an Ni alloy wire which has a composition consisting of, by weight, ≤0.1% C, ≤0.15% Si, ≤0.15% Mn, 12.0 to 20.0% Cr, 11.0 to 14.0% Co, 5.0 to 7.0% Mo, 2.5 to 4.0% Ti, 1.5 to 3.0% Al, 0.80 to 1.50% W and the balance Ni with inevitable impurities and containing at least either of 0.001 to 0.020% B and 0.01 to 0.3% Zr if necessary or containing both of them as essential elements. This alloy wire is characterized in that crystal grains having twins comprise ≥30% of the crystal grains having ≥10μm shortest grain diameter in a cross section and the value of 0.2% proof stress ranges from 1,200 to 1,600 MPa.
