We construct the relativistic particle model without Grassmann variableswhich meets the following requirements. A) Canonical quantization of the modelimplies the Dirac equation. B) The variable which experiences {\itZitterbewegung}, represents a gauge non-invariant variable in our model. Henceour particle does not experiences the undesirable {\it Zitterbewegung}. C) Inthe nonrelativistic limit spin is described by three-vector, as it could beexpected.
