PROBLEM TO BE SOLVED: To provide a cutting parallel ruler capable of efficiently preventing the upward displacement of a rod plate part.SOLUTION: A circular saw guide tool comprises: a ruler lever 2 attached removably to a circular saw and arranged in a direction orthogonal to the advancing direction of a saw blade; and a guide member 5 disposed on one longitudinal side of the ruler lever 2 and having a guide face 11 parallel to the advancing direction of the saw blade abutting against the side face of a workpiece. The ruler lever 2 includes: a rod plate part 41 attached to the circular saw and arranged above the workpiece; a substrate part 42 arranged on one side of said workpiece and on the lower side of said rod plate part 41, and equipped with the guide member 5; and a connection part 43 for connecting one side of said rod plate part 41 and one side of said substrate part 42. There is provided an upward displacement preventing member 81 for preventing the upward displacement of the rod plate part 41 with respect to the substrate part 42, so that the upward displacement of the rod plate part 41 with respect to the substrate part 42 can be prevented. |
