PROBLEM TO BE SOLVED: To provide a step collapsing tool for a stepped roof capable of easily forming a collapsing part for attaching snow guard metal fittings on a joining step part of the stepped roof.;SOLUTION: A step collapsing tool for a stepped roof is provided with a main body 1 which can be placed on a stepped roof A. The main body is provided with: an under-step disposing part 4 which is provided below a joining step part 3 of a stepped roof plate 2 to be able to support the lower part of the joining step part 3; and an over-step disposing part 5 disposed above the joining step part 3, the under-step disposing part and the over-step disposing part provided vertically opposed to each other. The over-step disposing part 5 is provided freely rotatably to the main body 1, and is provided with a lever part 6 capable of rotatably operating the over-step disposing part 5. A collapsing surface part 7 which comes into surface pressure contact with the top face of the joining step part 3 from above by operating the lever part 6 to rotate the over-step disposing part 5 to make a predetermined range on the top face of the joining step part 3 flatly collapsed is provided in the over-step disposing part 5.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
