In recent years the requirement for use of natural energy has been increasing to solve the problems of the global warming and the shortage of petroleum resources. The wind power generation is one of promising power generation types in the future as well as the solar power generation, so that recently the amount of wind power generation has been increasing considerably. Although there are many wind turbine types in Japan, for example propeller type, darrieus type and savonius type. darieus type wind turbine with vertical axis is suitable for wind in Japan whose direction is not fixed. This paper described that the effects of flow around blades of wind turbine on the circumferential force were clarified by flow visualization and PIV method. The circumferential force in wind turbine having aerofoil without camber is larger than in wind turbine having aerofoil with camber. The circumferential forces are generated in rotational angle of from 200° to 270° and from 300° to 340°, and the force in λ=3(λ :circumferential velocity ratio) is larger than in λ=1 because of the reduction of change of attack angle.
