The changes of the dynamical properties of A2063 with the distance to the center of the cluster are discussed. The velocity dispersion increases with the distance from the central region of the cluster and decreases in its outer rings. Such an inverted profile of velocity dispersion might be the result of occurrence of dynamical subclusters and/or of circularization of galactic orbits. The existence of subclumps of galaxies in A2063 has been confirmed by the values of the Dressler-Shectman δ-parameter and the spatial distribution of galaxies. Besides, the ratio of the number of ellipticals and the SO galaxies to that of spirals and irregulars decreases with distance from cluster center. The cD galaxy of A2063 has statistically significant peculiar velocity and does not lay at the minimum of gravitational potential of the cluster. The dynamical properties of A2063 and MKW3s may result from the encounter (merger) event.
