    CPC classification number: H02K7/145 ,  B25F5/02

    Abstract: In an electric power tool in which an electric motor is mounted in a housing that has a half-split structure, positions of middle screw fastening portions when a left housing and a right housing are fixed to each other by screws are located between a front protruding coil portion and a rear protruding coil portion. In other words, the protruding coil portions are located on either the front side or the rear side of the position of middle screw fastening portions when the left and right housings are fixed to each other by the screws. Accordingly, it is possible to effectively utilize a dead space that is likely to be formed between the front protruding coil portion and the rear protruding coil portion.

    Abstract translation: 在其中电动机安装在具有半分体结构的壳体中的电动工具中，当左壳体和右壳体通过螺钉彼此固定时，中间螺钉紧固部分的位置位于前突出部 线圈部分和后突出线圈部分。 换句话说，当左右壳体通过螺钉彼此固定时，突出的线圈部分位于中间螺钉紧固部分的位置的前侧或后侧上。 因此，可以有效地利用在前突出线圈部分和后突出线圈部分之间可能形成的死区。

    Abstract: A power tool includes a tool-main-body part, an electric motor as a drive source, a grip part, which extends downward from the tool-main-body part and is configured to be gripped by a user, and a power-supply unit at a tip of the grip part. The power tool includes a controller configured to control the operation of the electric motor, the controller being located on the power-supply unit, and a display controlled by the controller and configured to indicate an operating state of the electric motor. The controller and the display each have a flat-plate shape and are disposed along a surface direction with respect to one another, and the display includes a first portion that overlies the controller and a second portion that projects beyond an end edge of the controller.
