たコイルスプリング。[Claims for Utility Model Registration] 1. In a coil spring in which the entire surface of a metal wire with a wire diameter d is coated with fluororesin, and the coil spring is formed with a coil diameter D and a coil pitch p, the final - Pitch of winding P. 1. A coil spring coated with fluororesin, characterized in that the coil spring is formed to be smaller than the coil pitch P, and the end face of the coil is in contact with a flat surface over the entire length of one turn at the final end. 2 The coil pitch Po of the final turn is set to 0, and the radius of curvature of the final turn is made larger than D/2 in order, and then larger than (D/2+d) at the end, so that the side surface of the coil wire on the end surface contacts the plane. A coil spring coated with a fluororesin according to claim 1 of the utility model registration, which is formed so as to be. 3 The pitch of the first turn of the coil is Po = d, and the final -
Utility model registration claim 1, in which the cross-sectional shape of the side surface of the wound metal wire is shaved off so that the cutout part becomes gradually larger in the distal direction, so that the end face of the coil is in contact with a flat surface over the entire circumference. Coil sprue coated with fluororesin. Ng. 4 Bend the end of the metal wire toward the center of the coil,
A coil spring coated with fluororesin according to Claim 1 of the Utility Model Registration Claim, which is formed so as to be separated from the flat surface with which the end surfaces of the Cochnot come into contact.
