の矢印Eのように排出される。In FIG. 3, a motor is built in the housing 1, and the saw blade 2 is driven by the motor through transmission means such as gears. Further, a saw cover 3 is fixed to the housing 1 so as to cover the saw blade 2. The saw cover 3 is provided with a chip discharge port 4 so that the cutting chips generated from the saw blade 2 when the work material is cut pass through the inside of the saw cover 3 by the rotation of the saw blade 2 to discharge the chips. It is discharged from the outlet 4 as shown by an arrow E in FIG.

経路を避けてリンク5が収納されている。Further, as shown in FIG. 3, the link 5 has a saw cover 3
The electric circular saw contained in the electric saw has a link chamber 6 as shown inside the saw cover 3 and is deeper by a as shown in FIG. 4 (a sectional view taken along the line AA in FIG. 3). The link 5 is housed so as to avoid the chip discharge path.

という欠点があった。In the above chip discharge structure, chips flowing in the saw cover 3 are as shown by arrows B and C in FIG.
When it flows like this, the cutting chips hit the link chamber wall 7 and the link 5 and fall in the direction of arrow F in FIG.
Due to the wind caused by the rotational force of the motor and the cooling wind of the motor, some of the chips are scattered in the direction of the operator, which makes it difficult to operate safely and accurately.
本考案の目的は、上記した従来技術の欠点をなくし、
携帯用電気丸のこの切粉の排出を円滑に行い、切削加工
時の操作性及び安全性を向上させることである。The object of the present invention is to eliminate the above-mentioned drawbacks of the prior art,
This is to smoothly discharge the chips of the portable electric circle and improve the operability and safety during cutting.
本考案は、被削材切削時におけるソーカバー内での回
転のこ刃による切粉の流れが、案内壁を設けることによ
り変わるという点に着目し、ソーカバー内の切粉の流れ
がスムーズになる様に、案内壁の形状及び配置等を工夫
したものである。The present invention focuses on the fact that the flow of cutting chips inside the saw cover due to the rotating saw blade changes when the work piece is cut, and the flow of cutting chips inside the saw cover becomes smooth. In addition, the shape and arrangement of the guide wall are devised.
本考案の一実施例を第1図、第2図に示す。本考案の
構造は下記の部分を除いては従来技術と同じである。One embodiment of the present invention is shown in FIGS. The structure of the present invention is the same as the prior art except for the following parts.
第1図、第2図に示すように、リンク室6入口上部に
切粉案内壁8を設けている。第1図において破線Cは、
切粉案内壁8の無い場合を示しており、切粉案内壁8を
設けることにより、切粉の流れは破線Cから案内壁8に
沿って変化し、実線C′のように流れになる。As shown in FIGS. 1 and 2, a chip guide wall 8 is provided above the entrance of the link chamber 6. The broken line C in FIG.
It shows the case where there is no chip guide wall 8, and by providing the chip guide wall 8, the flow of chips changes from the broken line C along the guide wall 8 to a flow as indicated by the solid line C ′.
以上のことにより、被削材切削時にのこ刃2の回転に

きる。As described above, the cutting chips due to the rotation of the saw blade 2 during cutting of the work material do not collide with the link chamber wall 7 and the link 5, and the chips are smoothly discharged from the cutting chip discharge port 4. Therefore, the cutting chips fall downward, and it is possible to prevent the cutting chips from scattering toward the operator due to the wind generated by the rotation of the saw blade 2 and the cooling air from the motor, which improves the operability and safety of the operator. Can be improved.
本考案によれば、ソーカバー内側のリンク室入口上部

ができる。According to the present invention, the chip guide wall is provided above the link chamber inlet inside the saw cover, so that the chips collide with the link chamber wall and the link and fall downward, and wind caused by saw blade rotation and motor cooling air flow. As a result, it is possible to prevent scattering toward the worker.
