The motion of a linear two-wheel vehicle model is described using a one-degree-of-freedom damped vibration system with the rear wheel attack angle as a state variable. The transfer function of the attack angle of the rear wheel to the front steering angle input is the 0th order of the second order. Also，the numerator of the transfer function of the rear wheel attack angular velocity has only the first-order term. Using these two transfer functions，we interpreted the physical meaning of the numerator of the transfer function of the yaw rate and vehicle sideslip angle with respect to the front wheel steering angle. It was shown that each transfer function can be expressed by a combination of the turning (orbital) motion of the rear wheels and the rotational motion of the car body with respect to the turning trajectory.
