PROBLEM TO BE SOLVED: To provide a fan cover of a freezer, which secures both sufficient rigidity of a fan cover main body and an exhaust area in a fan cover air flow part, and further performs efficient defrosting, thereby making it possible to sufficiently derive the freezing capability of the freezer. SOLUTION: The fan cover can secure the rigidity of a fan cover main body by providing a metal frame 10 formed from a metal plate, and a heater plate 30 in an air flow part 11, and can secure sufficient exhaust area by forming an air flow part 11 from a metal wire 20. Further, the fan cover can perform efficient defrosting by providing a linear heater 40 on the back faces of the metal frame 10 and heater plate 30. As a result, the fan cover can be configured to derive the freezing capability thereof sufficiently. COPYRIGHT: (C)2005,JPO&NCIPI
