• We investigate the dynamical structure of an extended object in field theory which admits static classical solutions with stringlike structure without magnetic sources. The stringlike object is specified with its two end-points and field excitations confined in the object. The Hamiltonian of the system in the non-relativistic approximation takes the form similar to that of a rotating elastic bar, though the mass density depends on the direction of the motion. The center-of-mass motion and the internal motion are no longer independent, so that the size of the extended object becomes momentum dependent. The internal field excitations, some of which correspond to the vibrations of the string line, yield an extra potential for the internal motion.
