Wind other radially inward is formed so as to pass through the connection passage in the center of the guide surface. May be vanes is formed in an end portion leading to each of the connection paths of the upper guide plate and the lower guide plate. As the rotational force in a direction received from the rotational force in a direction and the other radially inwardly of the wind receiving from one radially outward of the wind is the same, it defines an inclination with respect to the radial direction of the blades between one and the other It is.

The impeller 90 has a guide surface for changing the orientation of the wind flowing along the axis L, and the direction and the radial direction flows along the axis L is synthesized orientation. And a vertical vane for receiving a rotational force by the wind direction containing a component of the radial direction.
