KCuCl$_3$ is a three dimensionally coupled spin dimer system, which undergoesa pressure-induced quantum phase transition from a gapped ground state to anantiferromagnetic state at a critical pressure of $P_{\rm c} \simeq 8.2$ kbar.Magnetic excitations in KCuCl$_3$ at a hydrostatic pressure of 4.7 kbar havebeen investigated by conducting neutron inelastic scattering experiments usinga newly designed cylindrical high-pressure clamp cell. A well-defined singleexcitation mode is observed. The softening of the excitation mode due to theapplied pressure is clearly observed. From the analysis of the dispersionrelations, it is found that an intradimer interaction decreases underhydrostatic pressure, while most interdimer interactions increase.Comment: 4 pages, 5 figures, 1 table, jpsj2.cls, to be published in J. Phys.  Soc. Jpn. Vol.76 (2007), the graphic problem of Fig.2 was fixe
