PCT No. PCT/DE81/00054 Sec. 371 Date Nov. 23, 1981 Sec. 102(e) Date Nov. 23, 1981 PCT Filed Apr. 2, 1981 PCT Pub. No. WO81/02992 PCT Pub. Date Oct. 29, 1981.A pot shaped housing insert (6) is arranged in a driving apparatus for fastener elements, such as nails, between a pot shaped main body (2) and the driving cylinder (12). In such a driving apparatus the excess driving energy is taken up by an impact buffer (11) made of elastic material. The housing insert (6) is made of a synthetic material having a high inner damping, so that the excess driving energy and thus the impact noise are dissipated to a large extent already in the housing insert (6). Thus, the operator is not exposed to any unnecessary nuisance and the housing (1) may be manufactured more easily in an economical manner at lesser expense.
