To provide a portable cutter including a dust box for collecting cut powder caused by cutting of a siding board and the like and having enhanced operability in installation and removal of the dust box.SOLUTION: Axial force of a joining shaft 61 is generated and released by changing an amount of fastening of a male screw part 63a relative to a second shaft part 64 by rotation operation of an operation part 65. A hooking part 64d is hooked on a shaft holding part 62 with the axial force of the joining shaft 61, and a dust box 50 is joined to the fixing cover 23 side. The dust box 50 is removed by displacing the hooking part 64d in a radial direction by loosening the axial force of the joining shaft 61 to separate the joining shaft 61 from the shaft holding part 62.SELECTED DRAWING: Figure 8 【課題】サイディングボード等の切断により発生する切断粉を集塵するためのダストボックスを備えた携帯用切断機において、ダストボックスの取り付け、取り外しの操作性を高める。【解決手段】操作部６５の回転操作により、雄ねじ部６３ａの第２軸部６４に対する締め込み量を変化させて結合軸６１の軸力を発生、開放させる。結合軸６１の軸力により引き掛け部６４ｄを軸保持部６２に引き掛けてダストボックス５０を固定カバー２３側に結合する。結合軸６１の軸力を緩めて、引き掛け部６４ｄを径方向に変位させて、結合軸６１を軸保持部６２から離脱させることで、ダストボックス５０を取り外す。【選択図】図８
