Abstract

The invention provides a fan motor apparatus and a method for manufacturing the same. A fan motor includes: a frame bushing part configured to house a rotation drive part; a bearing configured to rotatably support a shaft with respect to the frame bushing part; and at least one shaft fall-out restraining member provided on the shaft and configured to hold the bearing along an axial direction of the shaft.

Description

Technical field [0001] The invention relates to a fan motor device and a manufacturing method thereof. Background technique [0002] At present, various structures have been proposed for the technology for preventing the off-axis of the fan motor device. In the fan motor device, a retaining ring is used in the fixing structure of the bearing and the shaft of the fan motor (refer to Japanese Patent Publication No. 2002-138989, etc.). As the buckle ring can be C-shaped retaining ring and E-shaped retaining ring. [0003] image 3 An example of a fixing structure of a bearing and a shaft of a fan motor using a retaining ring in a conventional fan motor device is shown. As the buckle ring can be C-shaped retaining ring and E-shaped retaining ring. [0004] Such as image 3 As shown, in the bearing fixing structure of the fan motor device using the retaining ring, one end of the bearing 123 is fixed by the retaining ring 101. The buckle 101 is fixed by being inserted into the groove 151...
