Abstract
A slide-type cutting machine ensures safer operation of cutting wood or the like and can be housed in a compact state. A linear guide unit 3 includes a slide shaft 33 moving in a direction perpendicular to the moving direction of a cutting section 4, a first slide holder 31 for guiding the movement of the slide shaft 33, and a second slide holder 34 located at a lower end of the slide shaft 33 and for restricting the movement of the slide shaft 33 by abutting against the first slide holder 31. A linkage element 5 includes a first link 51 having one end connected to the cutting section 4 and the other end connected to the second slide holder 34, and a second link 52 having one end connected to the first slide holder 31 and the other end connected to the first link 51.
