Title (EN) PISTON ASSEMBLY AND FLUID PRESSURE DEVICE
(FR) ENSEMBLE PISTON ET DISPOSITIF À PRESSION DE FLUIDE
(JA) ピストン組立体及び流体圧装置
Abstract:
(EN) According to the present invention, a fluid pressure cylinder (10A) includes a piston assembly (17A). A piston main body (38) of the piston assembly (17A) includes a piston-side engagement part (40). A piston rod (20) includes a rod-side engagement part (42) that engages the piston-side engagement part (40). One of the piston-side engagement part (40) and the rod-side engagement part (42) is inserted into the other from the side, and the engagement parts thereby engage so as to restrict mutual displacement between the piston main body (38) and the piston rod (20) in the axial direction.
(FR) Selon la présente invention, un vérin (10A) à pression de fluide comprend un ensemble piston (17A). Un corps principal (38) de piston de l'ensemble piston (17A) comprend une partie de mise en prise côté piston (40). Une tige (20) de piston comprend une partie (42) de mise en prise côté tige qui vient en prise avec la partie (40) de mise en prise côté piston. L'une de la partie (40) de mise en prise côté piston et de la partie (42) de mise en prise côté tige est insérée dans l'autre par le côté, et les parties de mise en prise viennent ainsi en prise de façon à limiter un déplacement mutuel entre le corps principal (38) de piston et la tige (20) de piston dans la direction axiale.
(JA) 流体圧シリンダ(10A)は、ピストン組立体(17A)を有する。ピストン組立体(17A)のピストン本体(38)は、ピストン側係合部(40)を有する。ピストンロッド(20)は、ピストン側係合部(40)に係合したロッド側係合部(42)を有する。ピストン側係合部(40)とロッド側係合部(42)は、一方の係合部が他方の係合部に側方から挿入されることにより、ピストン本体(38)とピストンロッド(20)との軸方向の相対変位を規制するように係合している。
