  We find integrals of motion for the recently introduced deformed
Ruijsenaars-Schneider many-body system which is the dynamical system for poles
of elliptic solutions to the Toda lattice with constraint of type B. Our method
is based on the fact that equations of motion for this system coincide with
those for pairs of Ruijsenaars-Schneider particles which stick together
preserving a special fixed distance between the particles.
