a gear case having a housing containing a drive motor, a handle attached to the housing, a rotary saw blade safety cover attached to an end of the housing, and disposed within the safety cover;
A circular saw comprising a rotary saw blade driven by the drive motor and a base disposed below the housing and with a lower part of the rotary saw blade protruding downward, wherein a dust case is provided above the housing and the gear case. is removably arranged, and a duct opening for guiding dust and air generated during cutting by the rotary saw blade to the dust case is opened in the tangential direction of the rotary saw blade and connected to the dust introduction passage; An exhaust passage that guides the air in the dust case to the lower part of the dust introduction passage is defined with the duct opening by a dustproof plate provided inside the gear case. A guide that covers the cutting section is pivotally mounted on the same axis as the rotary saw blade so as to be rotatable according to the cutting depth adjustment of the base, and an operating lever of the lower guard is mounted coaxially with the guide. Features a dust-proof circular saw.
