摘要：PURPOSE:To keep a satisfactory fixing strength by forcedly fitting a single winding portion and a double winding portion to a cylindrical projection in the enlarged-diameter state in close contact with each other. CONSTITUTION:As a metallic sheet member 1 is adapted to push in a sliding cylinder 8 against the elastic force of a return spring 9 by operation of a press machine 1, the forward end portions of the cylindrical projections 3, 3 press a compression coiled spring 2 to be compressed. The forward end portions of the cylindrical projections 3, 3 are pressed in a single winding portion W1 which is the fixed terminal of the coiled spring 2, and at this time, a taper upper end port 8c is opened in a through hole 8a. Accordingly, the single winding portion W1 is permitted to be in the enlarged-diameter state to obtain a satisfactory fixing strength.
