Abstract

PURPOSE:To improve the safety of the opening and closing of the hinge type opening and closing door of an inclined vehicle by operating a hydraulic assisting unit by means of the vehicle door opening signal and the detection signal of the vehicle degree of inclination detection switch and aiding in the door opening. CONSTITUTION:When vehicle stops without being inclined, a degree of inclination sensor 11 does not perform the hydraulic actuation of a hydraulic cylinder 8 because of its off operation. When the degree of inclination sensor 11 detects the inclination and a door switch 11 is actuated, a switch relay 16 is switched to the position of (b), an oil pump 17 is activated, an opening and closing door 19 opens, and a bypass valve 25 closes. Thus, a piston 8b in which pressurized oil is supplied to the primary pressure chamber 8A of the hydraulic cylinder 8 is pushed in the door opening direction and the door opening is assisted. When the switch relay 16 is set to the position of (a), the opening and closing valve 20 of an orifice pipe 21 is opened and the door is opened at a low speed. As a result of this structure, the safety of the opening and closing of the hinge type door of an inclined and stopped vehicle can be improved.
