Abstract
In a conventional impact generator, a grease receives centrifugal force by the rotation of a rotary member, thereby keeping away from surfaces of the rotary member and a weight. Consequently, insufficient lubrication is caused between the weight and a member (for example, a tappet and the like) which comes in contact with the weight. An impact generator D comprises an impregnating member capable of impregnating the grease. The impregnating member is extended from a vicinity of an inner peripheral wall surface of a chamber E1 for accommodating a rotary member and a weight to a position where the impregnating member comes in contact with the weight performing a circular motion.
