する車両用戸閉機械の緩衝装置。 The piston rod of a piston that slides in a single cylinder equipped with valve bodies on the left and right sides is combined with a door interlocking mechanism that has a connecting rod or rack that passes near the outside of the valve body, and provides a shock absorber when the door opens and closes. The function is to rapidly reduce the aperture hole in the valve body to control the amount of air passing through the exhaust air. a stepped connecting rod with a step attached thereto; a valve rod provided so as to be slidable in the vertical direction within the valve body; and a valve rod rotatably attached to one end of the valve rod and slidable with the connecting rod. Each time the rollers pass a step in the connecting rod, the valve rod changes the air circuit on the exhaust side inside the valve body and rapidly reduces the size of the throttle hole through which air passes. A shock absorbing device for a door closing machine for a vehicle, characterized in that it is configured to produce a shock absorbing effect on the door.
