A system of infinitely many mutually reflecting Brownian balls
in R^d \abstract An infinite system of Skorohod type equations
is studied. The unique solution of the system of equations is
obtained from a finite case by passing to the limit.
It is a diffusion process describing a system of infinitely
many Brownian hard balls and has a Gibbs state associated with
the hard core pair potential as a reversible measure.
