Claims

[Claims for Utility Model Registration] 1. A utility model comprising first and second cylinders arranged in parallel inside a main body, and a piston housed inside the first and second cylinders so as to be freely displaceable in the axial direction of each cylinder. , a cylinder device in which piston rods that are engaged with the respective pistons and protrude outside the main body are interlocked in their axial displacements by a coupling mechanism, for stroke adjustment of the first and second cylinders; A cylinder device characterized in that a stopper mechanism is provided at a position projecting to the outside of a main body of at least one piston rod of the first or second cylinder. 2 Comprising first and second cylinders arranged in parallel inside the main body, and pistons housed inside the first and second cylinders so as to be freely displaceable in the axial direction, and locked with each piston. The cylinder device is a cylinder device in which piston rods projecting to the outside of the main body are interlocked in their axial displacements by a connecting mechanism, and a stroke is fixed to a stopper mechanism for stroke adjustment of the first and second cylinders. A stroke adjusting mechanism is coupled to the inner side of the connecting mechanism, the stroke adjusting mechanism comprising a clot and a stop block fixed to the main body so that the stopper mechanism comes into contact with the stopper mechanism and stops its displacement. cylinder device.
