Referring to FIG. 6 , the odor backflow prevention unit 210 according to the first modified example has a first blocking unit 216a and a second odor backflow prevention unit 110 described with reference to FIGS. 1 to 5 . Since the structure and effect are the same except for the blocking part 216b, descriptions other than the first blocking part 216a and the second blocking part 216b will be omitted.

When there is no residual amount of wastewater between the first blocking portion 216a and the second blocking portion 216b provided in the odor backflow prevention unit 210 according to the first modified example, the gap S3 ), so that they can be non-contact with each other.

The gap S3 formed between the first blocking portion 216a and the second blocking portion 216b is formed between the first blocking portion 216a and the second blocking portion 216a and the second blocking portion despite a small amount of drainage water during drainage. It is possible to facilitate the provision of the discharge space S2 by making it easy to change the state of the part 216b.

That is, the gap S3 formed between the first blocking portion 216a and the second blocking portion 216b is formed between the first blocking portion 216a and the second blocking portion 216a despite a small amount of waste water during drainage. The two blocking portions 216b are separated from each other so that the discharge space S2 can be provided smoothly.

It is possible to prevent the gap S3 provided between the two blocking portions 316b from increasing.

Since the first blocking portion 316a and the second blocking portion 316b are integrally formed, a portion 316c where the first blocking portion 316a and the second blocking portion 316b are inevitably connected to each other This inevitably occurs, and the connected portion 316c inevitably has a predetermined thickness in manufacturing.

Here, if both the first blocking portion 316a and the second blocking portion 316b are formed thinly, the gap S3 provided therebetween is increased by the connecting portion 316c having a predetermined thickness. It is inevitable, and this may make it impossible to achieve the predetermined purpose of preventing the backflow of odors.

In order to prevent the above problem, if both the first blocking portion 316a and the second blocking portion 316b are formed thickly, it is not easy to change the state due to a small amount of drainage water W. cause other problems.
