To reduce the burden of a maintenance worker when using a support device for lifting a step of a passenger conveyor.SOLUTION: A support device 80 for lifting a step includes an operation lever body 82 having a tool mounting part 92 and an operation part 90, which are mutually inclined with a predetermined obtuse angle at a support part 94, a support base 84 for rotatably supporting the support part 94 of the operation lever body 82, and a step lifting tool 86 held by the tool mounting part 92. The step lifting tool 86 includes a cleat holding part sandwiching both-standing wall surfaces standing from a groove bottom of one of a plurality of cleats 70 extending along a traveling direction of a step 20 and a hole for lifting provided in the cleat holding part. The tool mounting part 92 includes a hole hanging part hung on the hole for lifting.SELECTED DRAWING: Figure 6
