A cylinder(40) mounted in a vehicle door horizontally and charged with fluid inside. A rod(30) is inserted into the cylinder to move in the longitudinal direction of the cylinder in response to the opening or closing of the door, and has a tubular way(32) and a hydraulic chamber(34) for storing fluid and moving the fluid charged in the cylinder laterally. A tubular way blocking element(20) is disposed at a side in the rod for opening or closing the tubular way by a solenoid valve(24) according to the movement of the door sensed by movement sensing elements(10) mounted at both sides of the tubular way blocking element in the rod.
