A shelter door 1 has a door 70, an opening/closing mechanism 3, a ratchet mechanism 4, etc. The door 70 is an inward-opening door that turns about hinges 71. The opening/closing mechanism 3 actuates due to a drive device 50. The door 70 turns due to the actuating of the opening/closing mechanism 3 and opens/closes an opening part 120. As the opening/closing mechanism 3 actuates, a lock bar 35 turns, and when the door 70 closes the opening part 120, the lock bar 35 comes into close contact with a turn-restraining device 21 under the urging of compression force.
