An impact tool includes a rotational impact mechanism which is attached to a spindle 7 rotated and driven by a motor, a rotational impact force generated by the rotational impact mechanism which is intermittently transmitted from a hammer 8 via an anvil 3 to a bit tool 4, thereby giving the rotational impact force to the bit tool 4, and the anvil 3 is provided with a buffer mechanism (rubber damper 13 ) performing a buffer function in a rotational direction and in an axial direction and also directly transmitting a rotational torque greater than a set value and the spindle 7 is fitted into the anvil 3 and the buffer mechanism (rubber damper 3 ).
