A portable circular saw providing high visibility to a cutting mark line and sufficient operability even in case of an angled cutting. A slant position fixing member upstands from a front side of a base, and a tiltable plate is provided pivotally to the base. A front end of a saw cover is connected to the tiltable plate by a pivot pin. A main body roratably supporting a circular saw blade is pivotally movable by a pivotal movement of the tiltable plate to change inclination of the circular saw blade relative to the base. The tiltable plate is positioned in confrontation with the slant position fixing member, and fastening unit fixes the tiltable plate to the slant position fixing member to maintain a desired inclination of the circular saw blade. The fastening unit includes a thread extending through an arcuate slot formed in the slant position fixing member and engaging the tiltable plate, and a lever fixed to one end of the thread. The lever has a pressure surface in pressure contact with an abutment surface of the slant position fixing member. The abutment surface is in a form of a slant surface. |
