ABSTRACT:
A hub of a fan wheel with improved attachment for a metal case. The fan wheel is composed of a hub with a storage portion and a plurality of blades arranged around circumference of the hub. A metal case with a magnetic part is disposed in the storage portion of the hub. A plurality of blocking chunks is disposed in the end side of the storage portion of the hub, and at least one hook is disposed at proper position in the end side of the storage portion of the hub. A plurality of ribs is disposed inside the storage portion of the hub. The metal case has a penetrated hole with a stopper in one end of the penetrated hole. A recess is set between the stopper and the magnetic part. Therefore, when the metal case is disposed in the storage portion, by hooking the hook in the end side of the storage portion of the hub in the recess between the magnetic part and the stopper and positioning the metal case with blocking chunks and ribs, the metal case is firmly attached in the storage portion of the hub so as to improve attachment and facilitate manufacture.
