PROBLEM TO BE SOLVED: To prevent generation of rotation load to sliders under conditions including those where large external force acts on a saw blade housing and where a wheel rolls on cutting chips and the like adhering to an upper surface of a second guide rail. SOLUTION: For moving the saw blade housing 11 along the pair of guide rails 7, 9 in the horizontal direction, the sliders 37, 39 comprising a hinge shaft 45 are provided to a first guide rail 7 go as to be smoothly moved in the horizontal direction, and the saw blade housing 11 is connected to the sliders 37, 39 so as to be freely vertically swung about the axial center of the hinge shaft 45, and the wheel 49 rolling on the second guide rail 9 is rotatably provided to the saw blade housing 11.
