<p>PROBLEM TO BE SOLVED: To provide an inexpensive platform door capable of physically preventing a person from falling to a vehicle traveling passage from a platform of a traffic facility without the necessity of increasing an output of a door engine on a vehicle side and without anxiety of intentional opening of the platform door by a passenger. SOLUTION: A difference is generated in positions of a thickness direction of the platform door 2 when the platform door 2 is located at a closed position and when the platform door 2 is at an opened position. When the difference is generated, inconformity is generated between a groove 7 on a lower part of the platform door 2 and a rail 8 that the groove 7 should travel. Or while the difference is generated, inconformity is generated between the platform door 2 and a door case into which the platform door 2 should be pulled.</p> |
