  Classical model S_{Dcl} of the Dirac particle S_D is constructed. S_D is the
dynamic system described by the Dirac equation. For investigation of S_D and
construction of S_{Dcl} one uses a new dynamic method: dynamic disquantization.
This relativistic purely dynamic procedure does not use principles of quantum
mechanics. The obtained classical analog S_{Dcl} is described by a system of
ordinary differential equations, containing the quantum constant $\hbar$ as a
parameter. Dynamic equations for S_{Dcl} are determined by the Dirac equation
uniquely. The dynamic system S_{Dcl} has ten degrees of freedom and cannot be a
pointlike particle, because it has an internal structure. There are two ways of
interpretation of the dynamic system S_{Dcl}: (1) dynamical interpretation and
(2) geometrical interpretation. In the dynamical interpretation the classical
Dirac particle S_{Dcl} is a two-particle structure (special case of a
relativistic rotator). It explains freely such properties of S_D as spin and
magnetic moment, which are strange for pointlike structure. In the geometrical
interpretation the world tube of S_{Dcl} is a ''two-dimensional broken band'',
consisting of similar segments. These segments are parallelograms (or
triangles), but not the straight line segments as in the case of a
structureless particle. Geometrical interpretation of the classical Dirac
particle S_{Dcl} generates a new approach to the elementary particle theory.
