An impact tool includes a second spring with restricted free movement. The impact tool includes a motor, a spindle rotatable with a rotational force generated by the motor, a hammer supported by the spindle in a manner movable in a front-rear direction and in a rotation direction, an anvil to be struck by the hammer in the rotation direction, a first spring constantly urging the hammer forward, a second spring that urges, forward, the hammer moving backward from a reference position, a hammer case accommodating the hammer, the first spring, and the second spring, and a movement restrictor that restricts movement of the second spring in an internal space of the hammer case.
