When the wheelchair drive activation switch (23b) of the switch (23) is operated by moving from e) to the tread surface of the movable tread (141) of the second wheelchair step (13) and the third wheelchair step (14). , The escalator starts slowly and the wheelchair steps (1
1) is moved horizontally in the transport direction, and the third wheelchair step (1
The forward rotation pinion (162) of 4) meshes with the rack (173) to operate the driving force transmission mechanism (16), and the bollard (144) penetrates the tread surface of the movable tread (141) on both sides of the rear side of the wheelchair. Restrict the movement of the wheels. Then, when the wheelchair step group (11) starts to move upward from the horizontal movement, the movable step plate (141) moves upward from the main body (140) as the second wheelchair step (13) moves upward. It is located on the same horizontal plane as the tread of the wheelchair steps (13) and forms the rest of the wheelchair (8th
See figure). Then, after that, the escalator accelerates and the motor (174) of the work-in-process device (17) is reversely driven to return the work-in-process device (17) to a normal state.
