Abstract

A hand-held percussion implement has a pneumatic (air-cushion) drive member 1 vibrated via a radially-extending tumble member 6; rotation of the drive member 1 is prevented by a projection 13 of the tumble member 6 being embraced by a pair of parallel pin elements 14, 15. The pin elements are mounted through bores 18 (19, Figure 2 not shown) in an extension 17 of the drive member 1 into blind bores 18' (19') in the rear wall 16 of the drive member 1, and are located immediately above a bearing sleeve 4 for a round head portion 5 of member 6. <IMAGE>
