PROBLEM TO BE SOLVED: To provide a wind power generator capable of reducing the weight of a support shaft rotatably supporting a hub in a state of being fixed to a support base.SOLUTION: A wind power generator comprises: a support base including a mount portion; a support shaft 6 having a proximal end portion 14 fixed to the mount portion, an intermediate portion 16 rotatably supporting a hub, and a distal portion 18 located farther than the intermediate portion 16 from the proximal end portion 14 and supporting a fixed side of a hydraulic pump; and at least one blade supported by the hub, the proximal end portion 14 of the support shaft 6 having a shape such that two section moduli with respect to neutral axes x and y orthogonal to an axis of the support shaft 6 and orthogonal to each other differ from each other. |
