To provide an excavation tool capable of efficiently excavating an installation hole of a station for termite control in the periphery of a building.SOLUTION: An excavation tool includes a hollow shaft 11, a cylindrical part 13 connected to a lower end of the shaft 11 through a support part 12 so that a central axis is on the same axis as a central axis of the shaft 11, a blade part 14 provided on the lower end of the cylindrical part 13, and a handle part 15 connected to the upper end of the shaft 11. The blade part 14 arcuately extends along a lower end of the cylindrical part 13, and has a pair of facing excavation blades. In each of the excavation blades, a blade tip of a rotational direction front end is bent outward in the excavation direction, and the whole blade toward a rotational direction rear end from an intermediate part is bent inward.SELECTED DRAWING: Figure 1
【課題】建物の周囲にシロアリ防除用ステーションの設置穴を効率よく掘削することが可能な掘削器具を提供する。【解決手段】中空のシャフト11と、支持部12を介してシャフト11の下端に、中心軸がシャフト11の中心軸と同一となるように接続された円筒部13と、円筒部13の下端に設けられた刃部14と、シャフト11の上端に接続されたハンドル部15を備える。刃部14は、円筒部13の下端に沿って円弧状に延びるとともに、相対する一対の掘削刃を備える。各掘削刃は、掘削方向に対し、回転方向前端部の刃先が外向き、中間部から回転方向後端部に向かう刃全体が内向きに曲げられている。【選択図】図１
