Abstract
A power tool, such as a hammer driver-drill (), includes a spindle () that is axially and rotatable supported inside a metal gear case (). A first cam () is affixed to the spindle so as to rotate therewith and is housed in the gear case (). A second cam () 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 () 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 () 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.
