いる。Next, a synthetic resin sheet 21 is temporarily installed above the vacuum forming mold 20 with a gap left therebetween. Then, the sheet 21 is heated and softened by a forming process of a well-known vacuum forming method, and forming is started in a flexible state. That is, the sheet 21 is sucked and molded along the surface of the vacuum mold 20 by vacuum pressure from a large number of vacuum holes (not shown) provided in advance on the surface of the vacuum mold 20 . At this time, the fan motor 14 is disposed in the vacuum mold 20 and constitutes a part of the vacuum mold 20.

ファンモータの固定方法を得るものである。Therefore, the sheet 21 is heated and softened along the shape of the vacuum forming mold 20 and the outer can part 14b of the fan motor 14 that the sheet 21 comes into contact with, and is adsorbed according to its cross-sectional shape. The fan motor 14 is fixed by biting into the wall 13a. The above steps complete the installation and fixing of the fan mom. Accordingly, this method does not require the time and effort required to use conventional tightening screws, and can significantly improve work efficiency and facilitate work automation, etc. In addition, it is possible to obtain an inexpensive and strong method for fixing a refrigerator fan motor, which eliminates the need for drilling holes in the inner box.
