    • A piston is reciprocally movably provided in a cylinder hole, and a piston is brought into contact by a pushing force of a returning spring with one end of a push rod (30) inserted and mounted from one end of a cylinder main body. The push rod has a coupling end (40) at its end to be brought into contact with the piston. An opening through which the push rod is to be mounted includes a through groove (76) formed at an end surface of the cylinder main body to have such a shape as to pass the coupling end in an inserting state where the longitudinal axes of the cylinder main body and the push rod are held substantially normal to each other and to prevent the coupling end from coming out in a mounting state where the longitudinal axes of the cylinder main body and the push rod are substantially aligned, and an insertion groove (73) formed in the side surface of the cylinder main body in such a manner as to be continuous with the through groove and adapted for passing a rod portion (74) in the inserting state. The push rod can be readily and easily mounted into the cylinder main body without using a mounting tool and a mounting part.
    • 活塞在气缸孔中可往复运动地设置,并且通过从气缸主体的一端插入并安装的推杆(30)的一端通过复位弹簧的推动力使活塞接触。 推杆在其端部具有联接端(40)以与活塞接触。 要安装推杆的开口包括形成在气缸主体的端表面处的通孔(76),以具有使得联接端在气缸的纵向轴线的插入状态下通过的形状 主体和推杆基本上彼此垂直地保持,并且防止联接端在气缸主体和推杆的纵向轴线基本对准的安装状态下脱出,并且插入槽(73) 形成在圆筒主体的侧表面上,以便与贯通槽连续并且适于在插入状态下使杆部分(74)通过。 推杆可以容易且容易地安装到缸主体中,而不使用安装工具和安装部件。
