(JA) 流体圧シリンダ
Abstract:
(EN) This hydraulic cylinder (10) is provided with a cylinder tube (12), a piston unit (18), and a piston rod (20). The piston unit (18) has: a piston body (40); packing (42) mounted on the piston body (40); a holding member (44) mounted on the piston body (40); and a magnet (46) held by a magnet holding part (58) of the holding member (44). The magnet holding part (58) has a notch (58a1) that is open on the outer circumferential surface of the holding member (44).
(FR) La présente invention concerne un vérin hydraulique (10) qui comprend un tube de vérin (12), une unité de piston (18) et une tige de piston (20). L'unité de piston (18) comprend : un corps de piston (40) ; une garniture (42) montée sur le corps de piston (40) ; un élément de maintien (44) monté sur le corps de piston (40) ; et un aimant (46) maintenu par une partie de maintien d'aimant (58) de l'élément de maintien (44). La partie de maintien d'aimant (58) a une encoche (58a1) qui est ouverte sur la surface circonférentielle externe de l'élément de maintien (44).
(JA) 流体圧シリンダ(10)は、シリンダチューブ(12)と、ピストンユニット(18)と、ピストンロッド(20)とを備える。ピストンユニット(18)は、ピストン本体(40)と、ピストン本体(40)に装着されたパッキン(42)と、ピストン本体(40)に装着された保持部材(44)と、保持部材(44)のマグネット保持部(58)により保持されたマグネット(46)とを有する。マグネット保持部(58)は、保持部材(44)の外周面にて開口した切欠部(58a1)を有する。
