PROBLEM TO BE SOLVED: To provide an automatic saw configured to prevent the danger of a saw blade thereof, equipped with a cutting auxiliary tool which efficiently assists the cutting of a tree branch.SOLUTION: A cutting auxiliary tool 1 having two plate-like parts moves in a way that a tree branch is interposed between the plate-like parts, and contains a saw blade 2 in a way that the saw blade 2 is parallelly spaced in both surfaces of the saw blade 2. Therefore, the cutting auxiliary tool 1 is configured to overlap so as to cover the whole blade edge of the saw blade 2 after cutting the tree branch.COPYRIGHT: (C)2014,JPO&INPIT【課題】自動ノコギリにおいて、ノコ刃による危険性の防止と同時に、効率よく木の枝の切断を補助する切断補助具を備えた自動ノコギリを提供する。【解決手段】切断補助具1は、二つの板状の部分を有し、板状の部分が枝を挟み込むように移動して、ノコ刃2の両面に対して平行に間隔をおいてノコ刃2を収納することにより、木の枝の切断後はノコ刃2の刃先全体を覆うように重ね合わさる構成とする。【選択図】図1
