description PROBLEM TO BE SOLVED: To provide an impact rotary output device having an impact mechanism capable of giving desired impact. SOLUTION: The impact rotary output device comprises a drive transmission unit 23 entering a rotary drive force, a rotary hammer 34 capable of rotating, a coil spring 31 making an anvil 36 for outputting the rotary drive force concentrically arranged and urging the rotary hammer 34 at an anvil 36 side, a rotary connection section 34d and connecting piece 36b transmittably locking the rotary drive force of the rotary hammer 34 with the anvil 36, V-shaped fitting grooves 23d and 34c and a slide ball 35 in which the rotary hammer 34 is relatively rotated against the drive transmission unit 23 by means of a rotational load from the anvil 36 to keep on sliding axially against the urging force of the coil spring 31 until locking of the rotary connection section 34d and connecting piece 36b is canceled, and an adjuster ball 25 and spherical recessed sections 26b and 26c for giving stress to the coil spring 31 in advance.
