ファン軸受部となる欠点を有していた。As shown in FIGS. 1(a) and 1(b), the bearing of a conventional fan is constructed by fixing a bearing boss 2 into which a fan shaft 3 is inserted into a spider 1 by welding or caulking 4.
A screw 15 for fixing the fan 7 was screwed into the bearing boss 2 to fix the fan 7. The bearing boss 2 is generally manufactured by cutting a round bar, but it has the disadvantage that it requires processing and processing costs, resulting in an expensive fan bearing part.
本発明は上記の点に鑑みてなされたもので、簡単な構造

するように構成した。In order to achieve the above object, the present invention includes forming a fan shaft insertion hole by burring the axial center of a spider, and inserting and fixing a ring of an appropriate width around the outer periphery of the burring to form a bearing part. . The actual manufacturing direction is to drill a hole leaving a burring part in the axial center of the spider, burring the burring part, fitting a ring around the outer periphery of the burring part, and using the burring-formed shaft hole with a caulking die and a caulking punch. The structure is such that the tip of the burring part and the ring are caulked during thorough machining, and at the same time a stepped part is formed on the inner wall of the shaft hole.
以下、本発明を第２図乃至第９図に示す一実施例によシ
詳卸１に説明する。Hereinafter, the present invention will be explained in detail with reference to an embodiment shown in FIGS. 2 to 9.

によって固定している。Using a 10-piece spider, fit the ring 12 onto the outer periphery of the bearing part 11 that has been burred on the shaft center, and then connect the ring 12 and the tip of the burred bearing part 11 to the end of the bearing part 11.
It is fixed by

Next, the ring 12 is fitted around the outer periphery of the burring part, and the tip of the burring part is curled outward.

内にかしめパンチ１８を嵌入しながらしごき加工する。Next, the shaft hole 15 of the spider 10 is fixed by the crimping die 17 and the crimping punch 18, the spike presser 19, the ring 12, and the presser fitting 20 of the spider 10.
Ironing is performed while inserting the caulking punch 18 inside.

In the course of finishing the above-mentioned ironing and machining, a stepped portion 23 is formed on the inner wall of the shaft hole 15. The stepped portion contacts the stepped portion of the fan shaft 3 and the spider 10 of the fan.
