Human locomotion system has 'pull-in effect', in which if the ground swings with specific frequencies in one's frontal plane, a human's gait rhythm changes into the ground swinging frequency from one's natural gait rhythm. However the cause of the effect is still not clear. This paper notices human's posture controlling system, and refers to the cause of pull-in effect with suggesting a dynamical human gait model which has two legs and posture controller. Firstly the features of pull-in effect are clarified experimentally and secondly the posture controller which works for stabilizing frontal body behavior is studied. Then a dynamical human gait model is established from the results. The model consists of two beams and a mass representing legs and center of gravity of one's body. It basically behaves passively, but only the posture is controlled actively. The model shows the features of pull-in effect very well, and looking at the behavior of the model, it is explained that the posture controller causes pull-in effect.
