Claims

[Scope of Claim for Utility Model Registration] An annular plate with an air intake hole as its inner periphery and a disc whose outer diameter is approximately equal to the annular plate are stacked concentrically with a distance maintained in the axial direction, and both plates are placed facing each other. In a rotary blade wheel of a turbo fan, which is connected by a plurality of blade pieces sandwiched between surfaces, and is attached by caulking a boss cylinder for fixing the drive shaft through the center hole of the disk; A boss tube is formed by punching out a plurality of protrusions along the inner peripheral edge of a washer having the same inner diameter as the washer, and the surface of the washer from which the protrusions protrude is concentrically opposed to one side of the disk, and the boss tube is placed on the washer. A turbofan rotary-winged vehicle characterized by its caulking.
