We have derived an analytic equation for time evolution of inclination angle ξ between the magnetic moment and the spin axis of radio pulsars under the assumption of magnetic dipole braking model. We find that ξ is sensitive to the characteristic time t_c and the initial inclination angle ξ₀ for a magnetic dipole torque. We note the maximum effect of alignment torque for pulsars born as almost orthogonal rotator. Implications of the alignment scenario are discussed.
