よって保持されている。2. Description of the Related Art A conventional portable circular saw is shown in FIGS. As shown in FIG. 4, a conventional portable circular saw includes a saw blade 2 driven by an electric motor, a saw cover 4 that covers the saw blade 2 and supports a base 3 that is a reference when cutting. The saw blade 2 has a rotatable protective cover 6, and the split blade 5 is mounted behind the saw blade 2 on the same straight line as the saw blade 2. The split blade 5 is always a saw blade 2 even if the cutting depth H is changed.
It is held by the interlocking mechanism so that the distance between the tip and the tip of the splitting blade 5 becomes h.

を提供することである。In the conventional portable circular saw as described above, if the cutting depth H of the saw blade 2 is reduced as shown in FIG. It became visible from the direction A, and the structure was such that a test finger 8 having a diameter of 12 mm, which determines whether or not the operator's finger was easy to enter, could enter the saw cover opening 9 until it touched the saw blade 2. For this reason, there is a disadvantage that the safety of the portable round is reduced. An object of the present invention is to solve the above-mentioned disadvantages and to provide a highly safe portable circular saw.

る。SUMMARY OF THE INVENTION The object of the present invention is to provide two walls sandwiching the vicinity of a fixed blade fixing portion in a saw cover so that a finger or the like of an operator enters the width of the split blade fixing portion storage chamber in the saw cover. It can be achieved by narrowing it so that there is no

As can be seen from FIG. 2 which is a cross-sectional view taken along the line AA in FIG. Blade fixing part storage room 10
Is provided with two walls 7, and the distance between the walls 7 is less than 12 mm so that the test finger 8 cannot enter. Since two walls 7 are provided in the split blade fixing portion storage chamber 10 as described above, even if the cutting depth of the saw blade 2 is reduced so that the saw cover opening 9 becomes visible as shown in FIG. The test finger 8 cannot enter.

性を向上させることができる。According to the present invention, when the cutting depth of the saw blade is reduced, the opening of the saw cover can be seen. However, two walls are provided behind the saw cover so that the test finger cannot enter. Since the width of the fixed part storage room is reduced, even if a worker's finger or the like accidentally enters the saw cover opening, it does not contact the saw blade, improving the safety of the portable circular saw. be able to.
