接触して配置されている。 An annular welding leg 21 is formed on the connecting tube 12 . The connecting tube 12 is arranged so that its welding leg 21 surrounds the protrusion 20 of the hydraulic cylinder, and the tip of the welding leg 21 is arranged in contact with the outer surface of the hydraulic cylinder.
溶接脚２１の先端部の外周３０は任意の溶接手
段によつて溶接が施される。 The outer periphery 30 of the tip of the welding leg 21 is welded by any welding means.
