Claims

[Scope of utility model registration request]

In a fan impeller in which a blade plate is sandwiched between a disc-shaped main plate and a hollow disc-shaped side plate arranged concentrically and parallel to the main plate, the back surface of the blade plate in the rotation direction and the side plate are A device for preventing dust from adhering to a fan impeller, which includes a buried plate that straddles the corner formed at the joint of the blade plate and the side plate so as to come into contact with both the blade plate and the side plate.
