We investigate the strong decay of the isobar in the covariant quark model. The detailed derivation of the relativistic three-quark current with the quantum numbers $${J^P} = \frac{3}{2}^{+}$$ is given. It is shown that this current has a unique form. The decay width is calculated by fitting the free parameter of the model. The behavior of the strong form factor GΔpπ(Q2)for spacelike squared transferred pion momentum is obtained.
