摘要

PROBLEM TO BE SOLVED: To provide a cutting device capable of cutting a pavement surface in a circular shape of an arbitrary radius in a short time without requiring much labor. SOLUTION: A cutting device is provided with a base plate 11 fixed in an arbitrary position of a pavement surface GL for becoming a fulcrum an expandable arm 13 whose base end part is fitted to this base plate 11 so as to be turnable in the horizontal direction, a cutting blade 14A fitted to the end of the arm 13 so as to be projected below, and a motor 14B for driving this cutting blade 14A. The device is also provided with a wheel 16 turnably fitted around an axis parallel to the axial direction of the arm 13 and supporting the arm 13 almost in parallel with the pavement surface.
