We analyse the appearance of coherent motion in the dynamics of the Langevin equation in the subtle case of I＜1, and show that stochastic resonance does exist even in the non-critical case I＜1. Moreover, we show the monotonicity of the rotation number and discuss the relationship between the center frequency of the power spectrum peak and the rotation number
