PROBLEM TO BE SOLVED: To mount a control circuit on a substrate mounting a switch mechanism which is actuated by a trigger, for eliminating mutual wiring, for improving assembly work property and size reduction of a housing.SOLUTION: A housing 1 comprising: a trunk part 2 for storing a brushless motor 10 and an output part 30 to which a tip end tool is connected; a handle part 3 whose one end is connected to the trunk part 2; and a storage part 4 disposed on the other end of the handle part 3, is used. A control circuit IC81 formed by a hybrid IC is mounted on a switch substrate 7 mounting a switch mechanism 6 actuated by a trigger 5, and the control circuit is disposed in the trunk part 2.SELECTED DRAWING: Figure 1 |
