The effect of hydrostatic pressure on the incommensurate antiferromagnetic structure of CeRhIn5 is investigated with neutron diffraction using a He pressure cell. At 3.8 kbar, the staggered magnetic moment is 0.37(4) Bohr magneton per Ce at 1.6 K, which is the same as the ambient-pressure value. The Neel temperature TN=3.8(1) K is also the same as the ambient-pressure one, although the curve of order parameter has changed by pressure. The incommensurability "delta" of the magnetic wave vector qM=(1/2,1/2,"delta") has reduced from "delta"=0.297 at ambient pressure to "delta"=0.294(1) at 3.8 kbar.
