Conditional averages of longitudinal, normal velocity and of their products have been obtained in a fully developed plane turbulent wall jet. For detecting the coherent structure, the VITA technique were utilized in the inner region of the wall jet. It was inferred from the ensemble averaged patterns of u-and v-fluctuating velocities that the existence of a pair of counter-rotating spanwise vortices was supported through most of the present wall jet. The strong outflow events found near the location of a detective probe correspond to the trunk of a pair of spanwise vortices, where the ensemble averaged Reynolds shear stress takes a peak value.
