摘要： A vertical axis wind turbine (2) includes a vertical rotation shaft (3a) and a plurality of vertical blades (5) arranged around the rotation shaft and attached to the rotation shaft through an arm (6a, 6b). Each of the blades (5) includes a blade main part (5a) and blade-tip inclined parts (5b) extending from upper and lower ends of the blade main part (5a) toward the rotation shaft (3a). Each of the blade-tip inclined parts (5b) has a smaller thickness than a thickness of the blade main part (5a). A wind power generating device (1) includes a vertical axis wind turbine (2) having the above configuration and a generator (3).
