To solve the following problems of a conventional movable platform fence: in an anti-vibration mechanism of the above fence, a door is less likely to be opened/closed if a distance between an anti-vibration rail and an anti-vibration block is too narrow, a clearance having an adequate width is provided between the anti-vibration rail and the anti-vibration block, and as a result, the door vibrates in the range of the distance when the door is fully closed, and the door, rail and the like are abraded.
This movable platform fence includes: door-side tapered guides 5 which are provided in portions that remain in the door pocket of the door 2 when the door 2 is fully closed and which have inclined surfaces; and door pocket-side tapered guides 4 which are provided in the door pocket and which have inclined surfaces brought into surface contact with the inclined surfaces of the door-side tapered guides 5 when the door 2 is fully closed.
