PROBLEM TO BE SOLVED: To obtain the escalator device with a step for a wheelchair which can detect the step for a wheelchair with a movable step deviating from a normal route at a main frame lower end at the operation time the wheelchair. SOLUTION: When the step 2 for a wheelchair with a support mechanism is move and raised from a horizontal part 16 to a slant part 17 at the lower end side of a main frame at the operation time for wheelchair, the movable step 6 of the step 4 for the wheelchair with the movable step plate is raised against the step part 5 by support mechanism 3. When this raise motion is restricted by an abnormality, the whole step 4 for the wheelchair with the movable step plate is supported by the support mechanism 3 and raised by the raise movement of the step 2 for the wheelchair with the support mechanism, At this time, the step part 5 of the step 4 for the wheel chair with the movable step plated is moved more upward than the route of a prescribed height. Thereby, the movement of the usual step 1 is controlled abnormally by the operation of a detection device 24 and the generation of the inconvenience such as the hurt of a related member is beforehand prevented.
