PURPOSE:To aim at improvement in durability for a machine at high speed, by varying pressure oil in a cylinder chamber by movement of a piston following a moving body, and generating a thrust in a direction against inertia force of the moving body. CONSTITUTION:A belt 24 of a second moving device is driven synchronously with a feed gear 14 of a moving body 12, and a piston 20 is tightly attached to the belt 24 and housed in the cylinder 18 installed inside the moving body 12. pressure oil is fed to cylinder chambers 32 and 34 at both sides of the cylinder piston 20, and it is discharged to the outside via a control mechanism 48. In this control mechanism 48, there is provided with a movable member having elastic flexibility, and receiving acceleration of the moving body 12, pressure oil in oil passages 44 and 46 out of these cylinder chambers 32 and 34 is controlled. Therefore, inertial force of the moving body 12 to be produced by deceleration is supported by the piston 20 via the cylinder 18, thus the inertial force to be added to a first conveyor 6 is reducible. |
