ABSTRACT:
An improved pneumatic impact imparting tool includes a follower which is slidably accommodated in a recess formed on the inner end part of a rotor in a pneumatic motor. The follower is formed with a projection for allowing a ball to come in contact with a cam face as it is rotated together with the rotor. When the ball reaches the top of the cam face, the follower is displaced in the axial direction and enters a recess formed on the inner end part of an anvil to collide against stoppers in the recess. Thus, rotational movement of the rotor is transmitted to the anvil in the form of intermittent turning movement of the latter.
