PROBLEM TO BE SOLVED: To provide an adjustable tool for an escalator, the tool capable of improving action efficiency by reducing time and effort of changing the grip of the tool.SOLUTION: A spanner 4, a ratchet wrench 5, a step driver 6, and a box wrench 7 are turnably connected to a support part 3 fixed to a distal end of a handle 2 relative to the support part 3 by a hinge 8. A recess 91 is formed in a fixing surface 31 of the support part 3. Protrusions 92 are fixed to fixing surfaces 42, 52, 62, 72 of base members 41, 51, 61, 71 to which the spanner 4, the ratchet wrench 5, the step driver 6, and the box wrench 7 are fixed. The desired tool out of the spanner 4, the ratchet wrench 5, the step driver 6, and the box wrench 7 is turned, and the recess 91 and the protrusion 92 are engaged with each other. Accordingly, the desired tool is used by fixing the support part 3. |
