摘要： An electric device body (10) in which a battery pack (27) including a plurality of battery cells (31) and a plurality of first terminals (34) is detachably mounted includes: a housing (12, 13, 14); a guide mechanism (45, 24); and a plurality of second terminals (23). The battery pack is configured to be attached to and detached from the housing along a first direction. The guide mechanism is provided at the housing and configured to define the first direction. The plurality of second terminals is configured to be connected to the plurality of first terminals upon attachment of the battery pack to the housing. The electric device body is characterized by: a pressed portion (22e, 22f, 60, 61) configured to be pressed against the battery pack in a second direction intersecting the first direction when the battery pack has been attached to the housing.
摘要翻译：一种电气装置本体（10），其中包括多个电池单元（31）和多个第一端子（34）的电池组（27）可拆卸地安装在其中，包括：壳体（12,13,14）; 引导机构（45,24）; 和多个第二端子（23）。电池组被构造成沿着第一方向附接到壳体并从壳体拆下。引导机构设置在壳体处并且被配置为限定第一方向。多个第二端子被配置为在将电池组附接到壳体时连接到多个第一端子。电气设备主体的特征在于：当电池组件已经附接到壳体时，按压部分（22e，22f，60,61）被构造成沿与第一方向交叉的第二方向压靠在电池组上。

摘要： To provide an electric working machine, in which a brushless motor is mounted, in order to improve energy efficiency. An electric working machine includes: a disk motor including a rotor having a permanent magnet pole, an output shaft fixed to the rotor and serving as a rotation center of the rotor and a stator configured to generate a magnetic field with respect to the rotor; and a housing configured to accommodate the rotor therein and to rotatably support the output shaft. The stator includes: a magnetic yoke facing the rotor; and a coil board provided on a surface of the yoke facing the rotor. The stator is fixed to the housing side. The coil board has an extension portion on an outer circumferential edge thereof. Electric circuit elements for a motor driving circuit are mounted on the extension portion.
