Abstract
A combination includes a casing having a base extending therefrom and an axle tube. The base has an axial hole, and at least one engaging portion is defined in an underside of the casing. The axle tube has at least one positioning portion on an end thereof. The axle tube is extended through the axial hole of the base, with the positioning portion of the axle tube being securely engaged with the engaging portion of the base. When an axle tube of different inner diameter or length is required, only an additional mold for the axle tube is required. It is not necessary to manufacture a mold for the whole casing.

A combination of a base and an axle tube for a fan motor, the combination comprising:
- a casing including a base extending therefrom, the base having an axial hole, at least one engaging portion being defined in an underside of the casing;
- and
- an axle tube including an axial hole, the axle tube further including at least one positioning portion on an end thereof, the axle tube being extended through the axial hole of the base, with said at least one positioning portion of the axle tube being engaged with said at least one engaging portion of the base;
- and
- a support member inserted into the axial hole of the axial tube, said support member including an outer circumference adapted to securely engage with an inner surface of said at least one positioning portion of the axle tube, thereby preventing said one positioning portion of the axle tube from disengaging from said at least one engaging portion of the base.
