We investigate the model of a complex particle that consists of a rigid shell and a nucleus. The nucleus is attached to the shell by nonlinear spings with assymetric elasticity. The particle's dynamics with the nucleus driven by a zero-mean force is considered. It is shown that the unidirectional motion of particle arises in the absence of spatial asymmetry of external media and influence. Microbiological relevance of the proposed model is briefly disscused.
