PROBLEM TO BE SOLVED: To reduce manufacturing costs by simplifying a structure of a bar heater installation part. SOLUTION: A heater cover 75 has a cover plate 76 covering a top face of a glass tube heater 70 and having the angle section, and a pair of right and left side plates 80L, 80R having mounting holes 82 for fitting caps 72 of both ends of the heater 70. A vertical plate 93 rises from a lower edge of a front-side top face plate 77. When the upper edge of the vertical plate 93 is fixed to a lower edge of a face at a storage compartment 15 side of a cooler 45 by a screw 95, the heater 70 and the heater cover 75 receiving the heater are kept in a state of being disposed at a lower part of the cooler 45 at a back side of the vertical plate 93. The vertical plate 93 has a function of protecting a duct 60 from heat of the heater 70, so that it is unnecessary to separately dispose a protective member. COPYRIGHT: (C)2009,JPO&INPIT
