摘要
The purpose of this invention is to curb contact between adjoining hammers or hammer assemblies. A hammer assembly according to one embodiment of this invention comprises a rotating member which rotates about an axis of rotation, and a weight having a greater specific gravity than the rotating member, supported by the rotating member and including a plate-shaped portion which extends in a direction which intersects with the axis of rotation, the hammer assembling being characterized in that the plate-shaped portion contains a first surface and a second surface on the opposite side from the first surface, and when, from among the plate-shaped portions, a first area having a thickness defined by the distance between the first surface and the second surface in the portion furthest away from the axis of rotation and a second area thicker than the first area are compared in terms of the surface area of the projected surfaces when viewed in the direction of the axis of rotation, the surface area in the first area is smaller than the surface area in the second area.
