効率をよくすることができる。The cutting chips pass through the dust guide groove formed in the gear cover 2 and are accumulated in the dust collecting case 1. The slide cover 7 is fitted to a rotation fulcrum 8 provided in the front portion of the gear cover 2, and is constantly pressed against the base 5 by a spring 9. The slide cover 7 is composed of a leaf spring 7a, a plate 7b, a slide cover 7c, and a slide cover 7d. The leaf spring 7a made of a steel plate has a U-shaped convex portion for mounting and fixing as shown in FIGS. 4 and 5. The slide cover 7 has a leaf spring 7a as shown in FIG.
The mounting portion has a concave shape. FIG. 5 shows a state in which the leaf spring 7a is fitted and attached to the slide cover 7. Leaf spring
7a is fixed by spring pressure. When the leaf spring 7a is worn by cutting for a long period of time, the dust collection efficiency can be improved only by replacing the leaf spring 7a.
