If the cutting width main body 7 is vertical and the guide bar 3 is horizontal (perpendicular to the cutting width main body), the upper end of the cutting width main body 7 and the bottom surface of the guide bar 3 abut. Therefore, the cutting width main body 7 can surely provide a cutting width guide when the thin plate 66 is cut.
Further, when the thick plate 67 is cut, as shown in FIG. 8, the engaging groove 24 is positioned on the upper side, and the core member 32 of the guide bar 3 is slid from the left end portion of the engaging groove 24 to thereby form the second positioning stopper. 29, when the cutting width main body 7 is vertical and the guide bar 3 is horizontal (perpendicular to the cutting width main body), the upper end of the cutting width main body 7 and the bottom surface of the guide bar 3 Since a 14 mm gap is formed and the cutting width main body 7 is positioned 14 mm below the state of FIG. 7, the cutting width main body 7 can surely provide a cutting width guide when cutting the thick plate 67.

Next, in FIG. 9, when cutting a wide plate such as a plywood, if the cutting width is insufficient with the length of the guide bar 3, the cutting width main body 7 is moved by the adjusting portion 36 provided in the guide bar main body 34. The cutting width ruler function can be stopped by rotating upward.
In this way, the cutting width ruler function is stopped in a state where the cutting width main body 7 is fixed by the adjusting portion 36 of the guide bar main body 34, and cutting can be performed with an electric circular saw tool in a free state.

In the second embodiment described above, the cutting width main body 7 is configured separately from the gradient ruler main body 2 in the first embodiment, but the cutting width main body is used to perform the cutting width ruler function. When it is desired to remove the fixing plate 25 from the vertical plate 22 by removing the screw 27 in the gradient ruler main body 2, the fixing plate 25 can be used as a main body for cutting width.
In the second embodiment, the cutting width main body 7 is further added to the gradient ruler in the first embodiment to achieve the gradient ruler function and the cutting width ruler function. A cutting width ruler for an electric circular saw tool can be used with the cutting width body.
