    The spin-1/2 stacked triangular antiferromagnet CsCu1−x_{1-x}Cox_xCl3_3 with 0.015<x<0.0320.015<x<0.032 undergoes two phase transitions at zero field. The low-temperature phase is produced by the small amount of Co2+^{2+} doping. In order to investigate the magnetic structures of the two ordered phases, the neutron elastic scattering experiments have been carried out for the sample with x≈0.03x\approx 0.03. It is found that the intermediate phase is identical to the ordered phase of CsCuCl3_3, and that the low-temperature phase is an oblique triangular antiferromagnetic phase in which the spins form a triangular structure in a plane tilted from the basal plane. The tilting angle which is 42∘^{\circ} at T=1.6T=1.6 K decreases with increasing temperature, and becomes zero at TN2=7.2T_{\rm N2} =7.2 K. An off-diagonal exchange term is proposed as the origin of the oblique phase.Comment: 6 pages, 7 figure
