摘要： A cylinder device includes a piston rod that is inserted into a cylinder so as to be movable back and forth. The piston rod has a rod portion that extends outside the cylinder, and a piston connected to an end portion of the rod portion, the piston moving in the cylinder in a slidable manner. The rod portion has a rod inner space formed in the rod portion, the rod inner space communicating with the piston-side chamber of the cylinder, a first communicating passage that connects the rod inner space and the rod-side chamber of the cylinder, and an orifice plug provided in the first communicating passage in a changeable manner. The piston is connected to the rod portion so as to cover a part of the orifice plug.

摘要： A cylinder device includes an annular cushion ring (10) that prevents collision between the cylinder head (3) and the rod head (6) at stroke end during contraction. The cushion ring (10) is formed by linking a plurality of ring segments (11) in a circumferential direction so as to have an annular shape. The ring segments (11) have a main body portion (12) and linkage portions (13) formed on both ends of the main body portion in the circumferential direction, the linkage portions linking the neighboring ring segments (11). The linkage portions (13) of the neighboring ring segments (11) are mutually overlapped in an axial direction of the cushion ring (10) and linked such that relative movement in a radial direction of the cushion ring (10) is restricted.
摘要翻译：气缸装置包括环形缓冲环（10），其在收缩期间在行程末端处防止气缸盖（3）与杆头（6）之间的碰撞。缓冲环（10）通过将多个环状片（11）沿周向连结成环状而形成。环形部分11具有主体部分12和在主体部分沿圆周方向的两端形成的连接部分13，连接部分连接相邻的环形部分11。相邻的环形部分（11）的连接部分（13）在缓冲环（10）的轴向方向上相互重叠并且被连接成使得缓冲环（10）的径向方向上的相对移动受到限制。

摘要： A piston of a fluid pressure cylinder comprises a sealing ring interposed in a sealing ring accommodation groove, a piston ring that is interposed in a piston ring accommodation groove of the piston and comprises a fractured portion, and a backup ring that is attached to an outer peripheral surface 45 of the piston 4 and contacts the sealing ring and the piston ring. A groove for holding the backup ring is not required, and therefore a diameter of the piston can be reduced relative to the sealing ring. As a result, attachment of the sealing ring to the piston is simplified.
