Abstract

PROBLEM TO BE SOLVED: To realize an entrance device for a station, which houses in a partition wall body with a small depth, first and second sliding doors placed in an overlapped state, when opening a door. SOLUTION: When a vehicle 1 arrives at a platform 5, both of the first sliding door 19 and the second sliding door 25 open and are housed into a door casing 8 of the partition wall 6, thereby opening the entrance 7. When opening a door, both of the sliding doors are overlapped each other in the door casing 8 of the partition wall body 6, so that a protruded portion 21 of the first sliding door 19 is fitted into a grooved recession portion 26 of the second sliding door 25. Thus, a thickness of the partition wall body 6 can be reduced, and the partition wall body 6 can be easily mounted even on the station having the platform 5 with a small width, and when the vehicle 1 does not arrive at the platform 5, this device prevents waiting passengers from entering a track side 2 of the vehicle 1, when the vehicle does not stay, thereby preventing occurrence of an inconvenience caused by the passenger entering the track side 2 of the vehicle 1, before happening.
