A stabilizing apparatus is provided, applicable to all kinds of vertical axis wind turbine (VAWT), including a plurality of ball units and at least a guiding unit. The guiding unit has a circular cross-section and forms a ring-shaped housing space inside for housing the ball units. The inner wall of the bottom of the ring-shaped housing space inside the guiding unit forms a ring-shaped guiding surface. The ring-shaped guiding surface extends from the center of the apparatus towards the brink of the circumference of the apparatus. The straight line connecting the edge of the inner circle and the edge of the outer circle of the ring-shaped guiding surface forms an angle of 0-45° to the horizon surface. When the present invention is installed with the wind turbine rotor of a VAWT and rotates with the wind turbine rotor synchronously, the ball units move outward along the ring-shaped guiding surfaces because of the centripetal force; hence, the rotational inertia of rotor system increases as the rotor rotation speed is increased by wind so that the wind turbine rotor can start with a lower starting torque and spin more stably.
