  However, in the case of the conventional structure, the ruler plate material is attached to the circular saw and is disposed above the workpiece, and is disposed below the ruler member on the side of the workpiece. A guide part provided on the side surface of the workpiece, and a substrate part provided with the guide member, and a connecting part for connecting one side part of the ruler plate part and one side part of the substrate part. When the circular saw is advanced by abutting, the ruler plate is attached to the circular saw side, and when the circular saw is advanced, the guide member is in sliding contact with the side surface of the workpiece. The plate portion and the lower substrate portion may be relatively displaced in the horizontal direction with the vicinity of the connecting portion as the center of rotation. Therefore, the cutting progress cannot be smoothly guided and the uniform width That the workpiece may not be cut It has a case.

  The present invention aims to solve these disadvantages. Among the present inventions, the invention according to claim 1 is detachably attached to a circular saw and is in a direction perpendicular to the traveling direction of the saw blade. A ruler plate material to be arranged, and a guide member provided on one side of the ruler plate material and having a guide surface parallel to the traveling direction of the saw blade that contacts the side surface of the workpiece, the ruler plate material, A ruler plate that is attached to the circular saw and disposed above the workpiece, and a substrate portion that is disposed on the side of the workpiece and below the ruler plate and is provided with the guide member. And a connecting portion that connects one side portion of the ruler plate portion and one side portion of the substrate portion, and both side surfaces in the width direction of the ruler plate portion and both side surfaces in the width direction of the substrate portion. Guide device for circular saw, characterized in that it is provided with an anti-skid mechanism capable of holding and holding at the same time A.

  The invention according to claim 2 is characterized in that the anti-sway mechanism includes at least one pressing piece capable of simultaneously pressing at least one side surface in the width direction of the ruler plate portion and one side surface in the width direction of the substrate portion, The other pressing member that can simultaneously press the other side surface of the ruler plate portion in the width direction and the other side surface of the substrate portion in the width direction, and the one pressing member and the other pressing member are pressed and moved toward each other. It consists of a screw mechanism.

  As described above, according to the present invention, the ruler plate material is detachably attached to the circular saw, and the guide surface of the guide member is brought into contact with the side surface of the workpiece to advance the circular saw. Thus, the saw blade of the circular saw can be moved straight along the side surface of the work piece and the work piece can be cut into a uniform width. Since both sides and both sides in the width direction of the substrate portion are provided with a holding mechanism capable of holding and holding at the same time, both sides in the width direction of the ruler plate and the width direction of the substrate portion are provided by the shaking mechanism. By holding and holding both side surfaces simultaneously, it is possible to prevent the upper ruler plate portion and the lower substrate portion from being displaced relative to each other in the horizontal direction. The upper ruler plate portion and the lower substrate portion can be prevented. The mutual steadying with the part can be performed, and the cutting progress of the circular saw blade is smooth. Can line guide, it is possible to cut the workpiece uniform width.

  Further, in the invention according to claim 2, the anti-stabilizing mechanism has at least one clamping force capable of simultaneously pressing at least one side surface in the width direction of the ruler plate portion and one side surface in the width direction of the substrate portion. The other pressing member capable of simultaneously pressing the other side surface in the width direction of the ruler plate portion and the other side surface in the width direction of the substrate portion, and the one pressing member and the other pressing member are moved in proximity to each other. Since it consists of a screw mechanism, the one pinching piece and the other pinching piece are moved close to each other by the screw mechanism, and the width of the ruler plate portion is determined by the pinching operation of the one pinching piece and the other pinching piece by this close movement. Both side surfaces in the direction and both side surfaces in the width direction of the substrate portion can be held at the same time, and the upper ruler plate portion and the lower substrate portion can be prevented from being relatively displaced in the horizontal direction. The upper ruler plate and the lower substrate Ukoto can, the cutting progression of the saw blade of the circular saw can be smoothly proceeds guide, it is possible to cut the workpiece uniform width.
