弹簧组件
摘要：
本发明提供一种低成本的弹簧组件。该弹簧组件包括螺旋弹簧(1)和一对限位器(2)，该限位器分别布置在螺旋弹簧(1)的相对端部，并且限位器(2)包括：板部件(3)，其紧靠螺旋弹簧(1)的端部并且在其中央部向螺旋弹簧(1)内部凹进；以及钩部件(4)，其固定于板部件(3)以保持螺旋弹簧(1)由自由长度缩短的状态。钩部件(4)包括：柱部(4b)，其由板部件(3)悬垂并伸入螺旋弹簧(1)的内部；以及折返部(4c)，其在柱部(4b)末端折返，以与另一折返部(4c)接合。在偏离螺旋弹簧(1)中心轴线的区域与中心轴线平行地布置折返部(4c)，以及，沿螺旋弹簧(1)的中心轴线，折返部(4c)的末端和柱部(4b)彼此相对布置。
摘要（英）：

A spring assembly manufacturable at low cost, comprising a coiled spring (1) and a pair of retainers (2) disposed at both end parts of the coiled spring (1). Each of the retainers (2) comprises a plate member (3) brought into contact with the end part of the coiled spring (1) and recessed, at its center part, to the inside of the coiled spring (1) and a hook member (4) fixed to the plate member (3) and holding the free length of the coiled spring (1) in a reduced state. The hook member (4) comprises a strut part (4b) suspended from the plate member (3) and extending to the inside of the coiled spring (1) and a folded part (4c) folded back at the tip of the strut part (4b) and formed continuously to each other. The hook member is characterized in that the folded part (4c) is positioned in an area horizontally deviated from the center axis of the coiled spring (1) and the tips of the strut part (4b) and the folded part (4c) are opposed to each other along the center axis of the coiled spring (1).
