り終わり検知部の防塵装置。 A portable device comprising a rotary blade driven by an electric motor, a saw cover that covers approximately the upper half of the rotary blade, a safety cover that covers the exposed portion of the lower half of the rotary blade and is pushed up when making a cut, and a base that sets the cut. In the circular saw, deformable elastic bodies are disposed on both end surfaces of the rotating roller of the end-of-cut detection section that protrudes by a minute amount from the bottom surface of the base, approximately in the center of the front of the base in the cutting direction, to support the rotating roller. A dustproof device for a cutting end detection part of a portable circular saw, characterized in that the end face part is pressed against the end face to seal dust from the outside.
