ABSTRACT:
A pair of tension bolts for applying tension to a pair of drum heads are screwed individually into nuts. These nuts are held individually by means of a pair of lug bodies which are fixed to a drum shell. The lug bodies, which are formed by die casting, are connected to each other by means of a connecting member. The connecting member, which has a uniform cross-sectional shape throughout its length, is formed by pressing a metal plate with a predetermined length, or by cutting a metal pipe into a predetermined length. Two opposite end portions of the connecting member are fitted individually in openings at the respective end portions of the lug bodies. A hole is formed in each end portion of the connecting member. The lug bodies and the connecting member are connected so that projections on the lug bodies are fitted individually in the holes of the connecting member.
