When the door body 1 is opened and moved as described above, as shown in FIG. 3, the piston rod 51 extends, and when the door body 1 opens and moves beyond the limit of the extension operation of the piston rod 51, The pressure receiving member 58 is separated from the magnet 51A, and the door body 1 is further opened and moved. Further, when the door body 1 is closed and moved by the automatic closing force of the automatic closing device 40, the magnet 51A comes into contact with the front end portion 58A of the pressure receiving member 58 in the middle thereof, so that the door body 1 further continues to move and close. As a result, the piston rod 51 that receives the load from the front end portion 58A of the pressure receiving member 58 starts to contract, and the brake device 50 is discharged while restricting the air inside the cylinder-type brake device 50 at this time. Since the valve is provided, the door body 1 is automatically moved to the fully closed position by the automatic closing device 40 by reducing the closing movement speed by receiving the braking force by the throttle action of the valve.

  Since the valve is of a type that causes the air to flow into the cylinder-type braking device 50 without restricting the air when the piston rod 51 extends, the opening movement of the door body 1 from the fully closed position or the like. Can be performed by a small force that causes the spring spring of the automatic closing device 40 to return and accumulate the spring force.

  In addition, the device for reducing the moving speed of the door body 1 when the door body 1 is moving toward the fully closed position as described above is not limited to the cylinder-type braking device 50.
