PURPOSE:To obtain a stable operation power for opening and closing doors without any excessive load on a battery by applying the constitution wherein compressed air from a reserve tank for body height adjustment is also used for actuating the doors. CONSTITUTION:In the constitution wherein a sliding type automatic door opens and closes actuated by an air cylinder device 3 via a link device, and a door locking device is turned 'ON' and 'OFF' on another air cylinder device 7, a reserve tank 2 is used as a pneumatic source for air supply to each cylinder device 3 and 7 via air supply passages 15-17. Said reserve tank 2 is for the accumulation of compressed air from a compressor 32 and used as well for a drive source to actuate air suspensions 34 and 35 for body height adjustment. And the downstream pipe of said tank 2 is provided with a reducing valve 43, a solenoid valve 46 having valves 44 and 45 for the control of door opening and closing, and speed control valves 47 and 48. |
