Abstract

PURPOSE:To reduce outer diameter of a seat coil and to allow more latitude in designing by winding seat coil of a barrel type coil spring end so that a shorter side of a coil material of which transverse section is rectangular comes to the radius direction. CONSTITUTION:The diameter of a barrel type coil spring is at the largest at the middle of a spring, and the diameter of a wire itself is reduced in tapered condition toward both end parts from the middle part, and furthermore, each half of a coil is constituted in flat spiral shape so that the wire materials do not interfere each other at the most compressed condition. Here, the appropriate length of both ends of a tapered rectangular-sectioned circular coil material which constitutes the coil spring is formed uniformly rectangular-sectioned, and a seat coil 3 is formed by winding the coil flat (about 3/4 of one round) so that the shorter side of the rectangular comes to the coil radius direction. The seat coil 3 is fitted to an annular hollow part formed in a spring seat 4 of a bed frame.
