  Instead of the Yukawa mechanism for intermediate- and short-range interaction
some new approach based on formation of the symmetric six-quark bag in the
state $|(0s)^6[6]_X,L=0>$ dressed due to strong coupling to $\pi$, $\sigma$ and
$\rho$ fields are suggested. This new mechanism offers both a strong
intermediate-range attraction which replaces the effective $\sigma$-exchange
(or excitation of two isobars in the intermediate state) in traditional force
models and also short-range repulsion. Simple illustrative model is developed
which demonstrates clearly how well the suggested new mechanism can reproduce
$NN$ data.
