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.

Abstract: A power tool, such as a hammer driver-drill (1), includes a spindle (26) that is axially and rotatable supported inside a metal gear case (41). A first cam (83) is affixed to the spindle so as to rotate therewith and is housed in the gear case (41). A second cam (84) is disposed around spindle such that it is rotatable separately with respect to the spindle and can be brought into contact with the first cam. Hammer-switching levers (95) are movable relative to the gear case between an advanced position, at which rotation of the second cam is restricted (blocked), and a retracted position, at which the rotational restriction on the second cam is released. Receiving members (89) are respectively interposed between the gear case and the hammer-switching levers and are configured to absorb vibration generated when a hammering operation is being performed using the power tool.
