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.

Abstract: An angle tool having an output shaft part the height of which is low is provided. The angle tool includes an output shaft having a chuck part capable of holding a bit, a shaft that is provided so as to intersect the output shaft and that transmits drive force to the output shaft, and a gear housing that accommodates the shaft. The entirety of the chuck part is disposed in the gear housing. The output shaft includes a bevel gear that receives drive force from the shaft, and the chuck part is disposed inside the bevel gear. The chuck part is disposed in front of the shaft so as to intersect an extended line of a center axis of the shaft.

Abstract: A driver-drill (1) includes a motor (16), a spindle (32), which is rotationally driven using rotational energy output by the motor (16), and a chuck (30), which rotates integrally with the spindle (32). The chuck (30) includes: a chuck body (31); a chuck sleeve (80), which is externally mounted on the chuck body (31); and two or more chuck jaws (67), which are provided in the chuck body (31) and which expand and contract relative to the rotational axis of the spindle (32) in response to manual rotation of the chuck sleeve (80). The spindle (32) may be integrally formed (in one piece) with the chuck body (31). In addition or in the alternative, the chuck body (31) may be rotatably supported by a bearing (42) disposed in a tube-shaped housing (6).

Abstract: An electrical apparatus comprises an extension portion extending in a direction that intersects the direction in which a battery attachment surface of a battery base extends. A battery includes a plurality of battery cells with negative electrode side end faces. The battery has negative electrode side holding portions adjacent to the exterior of each of the negative electrode side end faces. The negative electrode side holding portions are located closer to the inner region of the center of gravity of the apparatus than a virtual plane to which a lateral rear side of the extension portion and a lateral rear side of the battery are tangent.

Abstract: A battery pack includes: a battery; a notification unit configured to notify that a fully charged state is reached; a determination unit configured to determine whether the fully charged state is reached; a processing unit configured to execute a full charge process if the fully charged state is determined, the full charge process being one of causing the notification unit to make a notification and maintaining a possible state, in which making a notification is possible; and a factor detection unit configured to detect occurrence of a predetermined increase factor during execution of the full charge process, the increase factor leading to increase in a chargeable capacity of the battery as compared with the time when the fully charged state is determined. The processing unit stops the full charge process if occurrence of the increase factor is detected during execution of the full charge process.
