Abstract

An impact work machine has a housing (210), a rotation body (300) supported in the housing (210) so as to be rotatable about the rotation axis of the rotation body and rotationally driven, guide surfaces (251, 252) formed on the housing (210) as circular cylindrical inner surfaces formed about the rotation center axis of the rotation body (300), an impact body (400) having a circular cylindrical outer surface and rotating while rolling on the guide surfaces (251, 252) with rotation of the rotation body (300), and an impact work body (500) supported so as to be able to reciprocate in the direction perpendicular to the rotation center axis. The circular cylindrical outer surface of the impact body (400) applies continuous impact force to the impact work body (500) by colliding with the impact work body (500). The guide surfaces (251, 252) include band-like regions (251a, 252a) separated in the direction of the rotation center axis. A recess (255) recessed from the guide surfaces (251, 252) is formed between the band-like regions (251a, 252a).
