Therefore, the low temperature of the drain water flowing through the lower surface 25 of the inner guide 4 is not transmitted to the case body 3. Thereby, coupled with the fact that the outer surfaces 9, 12, 13, and 14 of the inner guide 4 are not in contact with the case main body 3, condensation in the case main body 3 can be reliably prevented.
