A new model of radiative π-meson decays of vector mesons in the chiral bag model is proposed. The quark-π-meson interaction has the form of a pseudoscalar coupling and is located on the bag surface. The vector meson decay width depends on the quark masses, the π-meson decay constant, the radius of the bag, and the free parameter Z2, which specifies the disappearance of the bag during the decay. The obtained results for the ω-and p-decay widths are in satisfactory agreement with the experiment.
