Fluid pressure cylinder

摘要

An object of the present invention is to provide a fluid pressure cylinder improved in assembling performance so as to easily fix a partition wall to a cylinder main body. A plurality of pistons 15a and 15b are incorporated in a cylinder main body 11, axially aligned with each other, reciprocable in an axial direction, and respectively provided with piston rods 17a and 17b. A partition wall 14 is attached to the cylinder main body 11 so as to form pressure chambers 21a and 21b. A stopper space is formed by an engagement groove 31 provided to the partition wall 14 and a slit 32 formed so as to extend in a transverse direction of the cylinder main body 11. A stopper 34 is inserted in the stopper space in the transverse direction of the cylinder main body 11 so as to fix the partition wall 14 to the cylinder main body 11.

主权项

1. A fluid pressure cylinder, comprising:
a cylinder main body having a cylinder hole in which a plurality of pistons provided with piston rods is incorporated, the pistons being axially aligned with each other, and reciprocable in an axial direction, the cylinder main body having an inner surface forming the cylinder hole; a partition wall which is attached in the cylinder hole of the cylinder main body so as to form pressure chambers, to which fluid is supplied, between the partition wall and the pistons, wherein the partition wall has an outer peripheral surface facing the inner surface of the cylinder main body, the outer peripheral surface being provided with a circular engagement groove; a stopper space which is formed by the circular engagement groove provided on the outer peripheral surface of the partition wall and a slit extending in a transverse direction of the cylinder main body, surrounding the engagement groove, and penetrating the cylinder main body to open to the outside; and a stopper which is inserted in the stopper space via the slit so as to fix the partition wall to the cylinder main body, wherein the slit has a width larger than an inner diameter of the cylinder hole.
