An impact structure for an impact power tool comprises: a hammer body rotatable by means of a driving actuator, and having at least one pawl member having an impact contacting area; and an operation body for rotating a bit for the impact power tool, having at least one wing member having an impact contacting area, which can be brought into contact with the impact contacting area of the pawl member. The operation body is rotated by intermittently hitting the pawl member of the hammer body against the wing member of the operation body in a rotational direction of the hammer body. The impact contacting area of the pawl member can be brought into point-contact or line-contact with the impact contacting area of the wing member.
