断時のこじりの原因となる問題があつた。In conventional battery-powered circular saws, as shown in FIGS. 1 and 2, a handle (4) is arranged in the center of the main body (6), and a circular saw blade ill is arranged on the negative side. In this case, the overall center of gravity of the battery-powered circular saw and the position of the handle (4) coincide, but there is always a constant distance t between this position and the circular saw blade +1), and when cutting, the handle (4)
4) The force F of pushing the body (5) with the main body (5) and the reaction force from the material to be cut caused a 7-ment FL to occur, causing the circular saw blade +1+ to twist during cutting.

According to the present invention, the circular saw blade can be tilted so that the center of gravity is on the circular saw blade part by adjusting the balance depending on the temperature and the battery, and the handle and the circular saw blade are positioned on the center of gravity, thereby preventing the circular saw blade from binding during use. This goal has been achieved.

The main body (5) has a saw blade cover part (6) in the center, a Tanabata storage area (7) on the - side of the saw blade cover part (6), and a battery storage area on the other side. (8) is provided, and the storage section (7) has a t-
A battery (3) is inserted into the battery compartment (8) through the opening and stored therein. A handle (4) is provided on the top of the saw blade cover part (6), and the handle (4) has a switch (9) that turns on and off the seventh blade (2).
) is provided. The rotating shaft (10) of the output shaft (2) is equipped with a gear shifter (11), which meshes with the reduction gear α of the output shaft (1'4). Saw blade f
A state in which il is sandwiched between fluffy 0(1), 05).
The circular saw blade (1) attached to the end of the output shaft θ has its road half located within a part of the saw blade cover (6) provided in the center of the main body (5). It is something that exists. Seven-ta (2) on the - side of the circular saw blade (fl), and 'g on the other side! The handle (4) is located above the circular saw blade (1).

By arranging the Kt-taper (2) on one side and the battery (3) on the other side, heavy objects are placed in a well-balanced manner on both sides of the circular saw blade (1). Since the blade (1) can be aligned with the center of gravity of the entire battery-powered circular saw, and the handle (4) is located above the circular saw blade +11,
Both the handle (4) and the circular saw blade (1) coincide with the center of gravity of the entire battery-powered circular saw. In the diagram, ◇ is f-cepo・ν
α7) is a box shear, (+9) is a bearing, ``Lower Guard'' is a blade mounting screw, and υ is a blade mounting screw.A surface plate is attached to the bottom of the main body (5). Inside is a support pin that supports the main body (5) on the surface plate EK.In addition, a damaged reinforcing plate example is fixed to the surface plate by welding, etc., and the reinforcing plate (2) is attached to a circular saw blade ( It is located in front of 1) and has a sharp tip.The reinforcing plate (goods) has a thin plate ink mark (to) that is vertically μ thrown.In this way, the thin plate ink mark b If the mark (B) is set vertically, the thin plate itself is the marking mark (B), so when viewed from above, the thick part of the thin plate will be parallel to the marking line, and the chips will be drawn upwards. The ink chase mark □□□ is clearly visible even when worn.
