Zusammenfassung:	A door opening/closing apparatus is provided to operate a compulsive discharge mechanism by simply pressing a manipulation section installed on a side wall of the interior of an electric vehicle. A door opening/closing apparatus includes a pneumatic cylinder(10), an air supply source(20), an air supply line, and an air discharge line. The pneumatic cylinder is connected to a door. The air supply line connects the air supply source and the pneumatic cylinder so as to supply the air provided from the air supply source to the pneumatic cylinder. The air discharge line discharges the air in the pneumatic cylinder to the outside. The door opening/closing apparatus includes a manipulation section for generating an electrical signal by manipulation of a user and a compulsory air discharge mechanism(100) operated by the electrical signal from the manipulation section to compulsorily discharge the air supplied to the pneumatic cylinder.
