ABSTRACT:
A rotary impacting apparatus comprises rotary member drivingly rotated about a rotational axis within a casing. An impact member is loosely held by the rotary member so as to be movable toward and away from the rotational axis within a limited range. A holder mounted to the casing slidably supports a reciprocative member to allow movement thereof toward and away from the rotational axis within a limited range. The reciprocative member has a contact surface which interferes with the impact member rotating about the rotational axis when the reciprocative member is positioned closest to the rotational axis.
