<P>PROBLEM TO BE SOLVED: To provide a hydraulic cylinder, in which piston rods can be arranged without being restricted by a cylinder inner diameter. <P>SOLUTION: Projection parts 42 and 43 projecting outside in the radial direction are arranged on outer peripheral side surfaces of pistons 27 and 28 in the reciprocating direction of the pistons 27 and 28, and the base ends of the piston rods 29 and 30 are fixed to the projection parts 42 and 43. The piston rods 29 and 30 are constituted so as to move in response to the movement of the pistons 27 and 28 and the projection parts 42 and 43. Thus, positions of the piston rods 29 and 30 can be optionally set in positions outside of outer diameter of the pistons 27 and 28 regardless of inner diameter of through-holes 13 and 14 (that is, inner diameter of a cylinder or outer diameter of the pistons 27 and 28). <P>COPYRIGHT: (C)2013,JPO&INPIT |
