Zusammenfassung:To stably fix a base.SOLUTION: In a fixing mechanism 70 of an electrically-driven trimmer 10, a pair of fixed shafts 71 are mounted over an upper end part and a lower end part of a first chuck part 62C and a second chuck part 62D of a base 60, and a cam part 75B and a fixed washer 74 are respectively arranged on the pair of fixed shafts 71. Thus, both of longitudinal end parts of the first chuck part 62C and the second chuck part 62D can be sandwiched by the fixing mechanism 70. Thus, a base cylinder part 62 can be suitably deformed over the axial direction as compared with a configuration in which pressing force applied to the second chuck part 62D from the fixed washer 74 is applied at one location on a longitudinal intermediate part of the second chuck part 62D, for example. Thus, cramping force for cramping a cylinder part 22A of a base cylinder part 62 can be made to uniformly act in the axial direction of the base cylinder part 62.SELECTED DRAWING: Figure 8 【課題】ベースを安定して固定する。【解決手段】電動トリマ１０の固定機構７０では、一対の固定軸７１がベース６０の第１チャック部６２Ｃ及び第２チャック部６２Ｄの上端部及び下端部に架け渡されており、カム部７５Ｂ及び固定ワッシャ７４が一対の固定軸７１のそれぞれに設けられている。これにより、第１チャック部６２Ｃ及び第２チャック部６２Ｄの長手方向両端部を、固定機構７０によって挟み込むことができる。このため、例えば、固定ワッシャ７４から第２チャック部６２Ｄに付与される押圧力が、第２チャック部６２Ｄの長手方向中間部の１箇所に付与する構成と比べて、ベース筒部６２を軸方向全体に亘って良好に変形させることができる。これにより、ベース筒部６２の筒部２２Ａをクランプするクランプ力をベース筒部６２の軸方向において均一に作用させることができる。【選択図】図８
