摘要： A battery pack houses first and second cell units that are composed of a plurality of cells, and has a positive electrode power source terminal and a negative electrode power source terminal. This battery pack is provided with a series connector capable of connecting, in series, the first and second cell units and a parallel connector capable of connecting, in parallel, the first and second cell units, and is capable of switching between a parallel connection voltage and a series connection voltage. In the case of attachment to the high voltage electrical device body, the series connector becomes conductive and the parallel connector pair is cut off by the action of the series/parallel switching terminal. In the case of attachment to a low voltage electrical device body, the state is returned to an initial state, the series connector is cut off, and the parallel connector pair becomes conductive.

摘要： In an upper cell unit (2146) and a lower cell unit (2147) comprising five battery cells, positive electrode terminals (2162, 2172) are set apart and aligned vertically, and negative electrode terminals (2167, 2177) are set apart and aligned vertically. When an electrical device body is rated at 36V, device-side terminals are in contact only at the upper terminals (2162, 2167), and short circuiting of the lower terminals (2172, 2177) is effected using a short bar 2059. When the electrical device body is rated at 18V, the upper and lower terminals (2162 and 2172, 2167 and 2177) are simultaneously made to contact the device-side terminals, and the upper cell unit (2146) and the lower cell unit (2147) assume a parallel connected state. Thus, it is possible to automatically switch the output voltage when a battery pack is mounted according to the difference in terminal shape on the electrical device body side.

摘要： Provided is a rotary tool with a compact tip tool holding portion (80). The rotary tool is provided with a sleeve (81) attached to an output shaft (41) to switch a tip tool (70) between a fixed state and a detachable state. The output shaft (41) has a through hole (46) formed therein radially penetrating from the inside to the outside of a mounting hole thereof. The through hole (46) has a steel ball (85) provided therein such that at least a part of the steel ball (85) overlaps at least a part of a case (10). The sleeve (81) defines a first position in the outward direction of the steel ball (85), while the case (10) regulates a second position on the radially outer side of the first position.

摘要： The electrical apparatus, in which a series connection state and a parallel connection state of an upper cell unit including five battery cells and a lower cell unit can be automatically switched by means of a difference in a terminal shape on the electrical apparatus body side, has a terminal holder and holds apparatus side terminals. The terminal holder, which establishes an electrically connected state with the connection terminals of the battery pack, is provided with two parallel protruding parts that extend in the forward-backward direction, and second rail grooves fitted to the protruding parts on the electrical apparatus side. Due to the fitting, relative movement of the terminal holder and the battery pack in the vertical direction can be suppressed, and wear on the apparatus side terminals can be greatly suppressed.
