PROBLEM TO BE SOLVED: To provide a door device with a door 9 that may be operated in an opposite direction with lesser force, by reducing energizing force of a pulling spring of a pulling mechanism 11 that pulls the door 9 to a closed or open position, while fully maintaining the door 9 in the closed or open position.SOLUTION: A door device includes: a door 9 that opens/closes a door opening 7; a pulling spring that energizes the door 9 in a moving direction at a trigger position near a stopped position when the door 9 moves from a starting position to the stopped position, assuming either an open position or a closed position of the door 9 as the movement starting position and the other as the stopped position; and a buffer mechanism that slows down movement of the door 9 realized by the pulling spring. The door 9 is not fully retained at the stopped position by the pulling spring alone. Magnet 22 is fitted and fixed on the door 9 side and a magnetic member 23 on a door frame 1 side. Thus, the door 9, which has been retained incompletely at the stopped position, is fully pulled in and retained at the stopped position by magnetic force working between the magnet 22 and the magnetic member 23.SELECTED DRAWING: Figure 1 |
