By pulling the main body 10 toward the eaves of the roof in this state, the main body 10 (the upper blade 3 and the lower blade 4) can be smoothly moved along a predetermined cutting position without bending and deforming the surplus roofing material 21A. Moreover, it can be moved straight, and the surplus roofing material 21A can be cut cleanly while leaving a gripping margin of a predetermined width for 23 minutes.

In addition, this embodiment includes a plurality of vertical rollers 5A having different diameters, and by changing the vertical rollers 5A, the positions of the cutting blades (upper blade 3 and lower blade 4) with respect to the vertical surface 22A of the arabesque 22 are changed (adjusted). Therefore, it is possible to always cut the surplus roofing material 21A while leaving a grasping margin of 23 minutes of an appropriate width for various keraba arabesque protruding portions 22B having different protruding amounts.

In addition, since the present embodiment is provided with a blade gap adjusting mechanism that adjusts the gap distance between the upper blade 3 and the lower blade 4, the upper blade 3 and the lower blade 3 are adjusted depending on the thickness of the surplus roofing material 21A to be cut. By adjusting the gap between the blade 4 and the blade 4 to an appropriate distance, the surplus roofing material 21A can be cut cleanly and smoothly, and the adjustment is performed by screwing the male screw member 8 into the male screw member 8. Since the adjustment can be performed by an extremely simple operation of merely adjusting the protrusion amount with respect to the upper blade mounting surface 1A, anyone can easily adjust the amount.

It should be noted that the present invention is not limited to this embodiment, and the specific constitution of each constituent element can be designed as appropriate.
