Abstract
An impact tool includes: a motor; a speed reduction mechanism rotated by the motor; a hammer rotated by rotation of the motor transmitted via the speed reduction mechanism; an anvil to be impacted in a rotation direction by the hammer; a motor case accommodating the motor; and a gear case accommodating the speed reduction mechanism. One or both of the motor case and the gear case are made of a magnesium alloy.
