摘要： A portable electric power tool including a housing (5) having one end to which an L-shaped battery pack (2) is installable. A motor (3) is accommodated in the housing. A switch assembly (19) includes a switch body (20, 20A, 20B) installed in the housing (5). The switch body (20, 20A, 20B) is overlapped with the L-shaped battery pack (2) in a longitudinal direction of the power tool. The switch assembly further includes a trigger (21) including a pivot portion (22), a manipulation portion (21a) extending frontward from the pivot portion (22) and pivotally movable, and a lever portion (21b) extending rearward from the pivot portion (22) to actuate the switch body. The manipulation portion (21a) is disposed to overlap with a center of gravity of an entire power tool (1) in the longitudinal direction, and the pivot portion (22) is positioned between the manipulation portion (21a) and the switch body (20).

摘要： The portable belt grinder 201 comprises: a main body 202 with an electric motor 203 built therein; a drive pulley disposed in the lower portion of the main body 202 and rotationally drivable by the electric motor 203; an idle pulley disposed as the companion to the drive pulley; and, an endless abrasive belt 215 wound between the two pulleys. In the portable belt grinder 201, in the portion of the main body 202 that exists in the vicinity of the abrasive belt 215, there is formed a hole portion 202f which is used to visually confirm the side end edge of the abrasive belt 215 from above. Also, on the upper surface of the main body 202, there is mounted a transparent cover 222 which is used to cover the hole portion 202f.
摘要翻译：便携式皮带磨床201包括：内置有电动机203的主体202; 驱动轮，其设置在主体202的下部，并由电动马达203旋转驱动; 作为与驱动皮带轮配套的惰轮; 以及卷绕在两个滑轮之间的环形砂带215。在便携式带式磨碎机201中，在存在于研磨带215附近的主体202的部分形成有孔部202f，该孔部202f用于从上方确认砂带215的侧端缘。此外，在主体202的上表面上安装有用于覆盖孔部202f的透明盖222。
