PROBLEM TO BE SOLVED: To provide a crack scale which allows a single operator to perform business loss compensation work easily.SOLUTION: A crack scale comprises: a flat plate-state gauge plate 2 on which a gauge scale 4 indicating various widths is displayed; a slide case 3 for slidably holding the gauge plate 2; and an attachment part 8 for detachably attaching the slide case 3 to a wall face. The slide case 3 is attached to a cracking position on the wall face. The gauge plate 2 is slid to the slide case 3 for positioning the gauge scale 4. In the state, if an operator images a cracking and crack scale by an imaging device, by a single operator, business loss compensation work for imaging a proof photograph indicating width of cracking can be performed. |
