Abstract. One can introduce socalled {\em Plain Mechanics\/} having
an {\bf operator realization}. Then the set of
onedimension representations of this operator realization
may be identified with the Classical Mechanics. Different
irreducible infinitedimension representations may be
recognized as Quantum Mechanics for different $\hbar$ (the
Planck constant). It can be done in the such manner that
the following diagram will be commutative.

Here the horizontal arrow is well known correspondence between
Quantum and Classical Mechanics if Planck constant tensing to zero.
A {\em realization\/} of this scheme for a particle in
$n$dimensional space by twosided convolutions on the
Heisenberg group is constructed. We also introduce the
{\em motion equations\/} for observables in this
realization. The left arrow of the given diagram carries
this equation to the Heisenberg one and the right arrow
maps it to the Hamilton equation.
