This paper reports the experimental results for the dynamic yaw action of horizontal axis small wind turbine. The authors have carried out the wind tunnel experiment to obtain the optimum design value for the yawing on small wind turbine. The models for wind tunnel experiment are turbine's diameter of 1m, blade number of 5 and 2 type tail wings (large, small). The authors evaluate the yaw action for changing number of turbine's rotation, area of tail wing and wind speed. This experiment shows the yawing tendency that the yawing angular velocity to become larger with increase of wind speed and area of tail wing, and it become smaller with increase of turbine's rotation. Furthermore, the maximum yawing angular velocity in this experiment became 3.84 rad/s that greatly exceeded the present design value 1rad/s at the wind speed of 10m/s.
