    • PROBLEM TO BE SOLVED: To stabilize attitudes of cotter segments and to prevent any engagement failure with a valve stem by a simpler arrangement.SOLUTION: A retainer assembling apparatus, in which a retainer is assembled to a valve stem via a cotter engaged with an engaging groove formed on the valve stem and comprising a pair of cotter segments, includes: a cylindrical body in which the retainer with the cotter mounted thereon is brought into contact with a lower end thereof and the valve stem can enter from the lower end; a holding portion which holds the retainer contacting the lower end of the cylindrical body; a push-up shaft which pushes up the pair of cotter segments into the cylindrical body; and an axial body which is arranged in the cylindrical body to be coaxial with the push-up shaft and to be coaxially movable. The cylindrical body includes a tapered inner circumferential portion formed in a tapered shape radially enlarged toward the upper part, on an inner circumferential wall lower portion thereof.
    • 要解决的问题:通过更简单的布置来稳定切口部分的姿态并防止与阀杆的任何接合故障。 解决方案:一种保持器组装装置,其中保持器经由与形成在阀杆上的接合槽接合并且包括一对开口段的开口组合到阀杆,包括:圆柱形主体,其中保持器 安装在其上的开口与其下端接触并且阀杆可从下端进入; 保持部,其保持保持器与筒体的下端接触; 上推轴,其将一对开口部分推入圆柱体; 以及轴向体,其布置在所述圆筒体中以与所述上推轴同轴并且可同轴移动。 圆柱体包括在其内周壁下部上形成为朝向上部径向扩大的锥形形状的锥形内周部。 版权所有(C)2013,JPO&INPIT
