In this fixed state, the upper half of the circular saw 4 is adapted to project upward from the table 23 of the stationary table 21. Further, in this state, the lower half portion of the circular saw 4 is provided with a cutting blade cover 41 formed in an arcuate groove shape along the cutting blade 43 of the circular saw 4. A dust collecting pipe 44 is provided at the bottom of the cutting blade cover 41, and the chips 31 collected in the cutting blade cover 41 can be collected through the dust collecting pipe 44. Furthermore, this round saw 4
The side surface 211 of the stationary table 21 provided with
A wall 24 is provided at a predetermined distance so as to face 11 and a circular saw 4 is provided in a gap between the wall 24 and the stationary table 21.
Is designed to be located. A slide rail 25 is provided on the upper side of the wall 24 along the upper side, and the slide base 22 is engaged with the slide rail 25.

On the other hand, the slide base 22 is supported by the slide rail 25 and a support leg 26 provided with a roller 27, and is slidable along the slide rail 25 in the arrow a direction. Also, this slide stand 22
An L-shaped angle 28 is fixed to the slide plate 22 so that the plate member 3 arranged on the slide base 22 can come into contact therewith. Then, the plate member 3 is arranged on the slide base 22 so as to fit the angle 28, and the slide base 2
By sliding 2 along the slide rail 25, the plate material 3 can be cut into a desired size by the cutting blade 43 of the circular saw 4 protruding from the table 23 of the stationary table 21. At this time, the position of the workbench 2 can be adjusted in advance by moving the handlebar 6 provided on the stationary table 21. Further, the start of the circular saw 4 is performed by the switch lever 7 provided on the stationary table 21. Further, the circular saw 4 projecting from the table 23 of the stationary table 21 is covered with a dust collector 8 from above to collect chips 31 scattered upward during cutting. Further, the dust collector 8 has a presser 81 for the plate member 3.
