The opening 141 on the front surface of the first water receiving portion 140 allows air to flow more easily than the other openings 142 and 143, and by increasing the size of the opening 141, the exhaust efficiency can be improved most. However, the opening 141 on the front surface of the first water receiving portion 140 is closer to the partition wall 132 than the other openings 142 and 143, and if the opening 141 is made too large, the water entering from the exhaust port 109 jumps over the partition wall 132. It becomes easier.

Further, (the height of the upper end of the partition wall 132) = D > (the height of the upper end of the rear wall 133) = E, and (the distance between the rear wall 133 and the opening 142 on the rear surface of the first water receiving portion 140) = C >0. Furthermore, a gap is formed between the upper end of the rear wall 133 and the first water receiving portion 140 . By doing this, even if the drain port 134 is not formed on the bottom surface 135 of the second water receiving portion 130b, the water that has entered from the exhaust port 109 can be made to climb over the rear wall 133 and be drained from above. can.
