Claims

[Claims for Utility Model Registration] 1. A cylindrical part provided on the central base of the blower blade is fitted onto a drive shaft, and a groove provided on the cylindrical part is engaged with a convex body provided on the drive shaft. In the case where the blower blade is attached to the drive shaft by appropriately securing the cylindrical portion to the drive shaft, the cylindrical portion may have an inner diameter larger than its outer diameter. A blower blade mounting device characterized in that a ring-shaped elastic body is attached, and the elastic body is pressed against the convex body so that the pressed portion is elastically deformed into a V-shape. 2. Utility model registration claim 1, characterized in that the elastic body has a mounting leg formed by cutting and raising a locking claw, and is attached by locking the locking claw to a cylindrical part. The installation device for the blower vane described in . 3. The cylindrical part is provided with ribs on the outer surface thereof, and the elastic body engages the mounting legs with the ribs to prevent rotation, as set forth in claim 1 of the utility model registration claim. Air blower blade mounting device. 4. Utility model registration claim 1, characterized in that the elastic body is formed into a V-shape that is shallower from the state before the blower blade is attached to the rotating shaft than after it is attached.
The installation device for the blower vane described in . 5. According to claim 1 of the utility model registration claim, the elastic body is provided with a mounting leg in a position that does not touch the outer surface of the cylindrical part even in a deformed state during the installation of the blower blade to the rotating shaft. Attachment device for the blower blades described.
