摘要： PROBLEM TO BE SOLVED: To provide a door opening/closing device advantageous in enhancing durability of a torsion spring used in a the door opening/closing device.SOLUTION: A shaft member 30 is unrotatably mounted on the side of a first door body 16. Both ends of a torsion spring 32 are locked to the side of a second door body 18 via torsion spring locking walls 3408, 3604 respectively, and an intermediate part of the torsion spring 32 is locked to the side of the first door body 16 via a locked part 3206, a locking part 4808, and the shaft member 30. When the first door body 16 and the second door body 18 are opened from a closed state of a doorway 12: the first door body 16 and the second door body 18 are bent around an outside cylindrical member 34; the outside cylindrical member 34 rotates relative to the shaft member 30; each of a first coil part 3202 and a second coil part 3204 is elastically deformed in a direction in which it is wound and tightened; and the first door body 16 and the second door body 18 are opened and the doorway 12 is opened.
