Abstract
An impact tool includes a hammer that is rotated by a motor and energized toward a front side from a spindle by a cam mechanism and a spring, and an anvil that is struck by the hammer. The hammer includes a main body part, and claw parts extending forward from the main body part, and tapered surfaces are formed such that an inner diameter side end of each of the claw parts of the main body part is located on the front side relative to an outer diameter side end of the claw part. The tapered surfaces are formed, on an outer peripheral side of a front facing surface of the hammer, in such a shape that the tapered surfaces recede as separating in a radial direction from a rotation axis.
