The drainage pipe, which is the drainage portion of the drainage guide pipe such as a bathtub, is inserted into the strainer, and the lower half of the drainage pipe is immersed in the accumulated water. Since it is configured so that it comes close to the bottom of the strainer, when draining the drainage of the bathtub through the drainage guide pipe, the drainage does not hit the bottom of the strainer as in the past and drainage noise is eliminated. It can be reduced as much as possible, and quiet drainage of stored water in the bathtub can be realized.

Since the strainer has a deep basket shape and the lower half part is immersed in the accumulated water in the drainage part, the hair mixed in the drainage will not be scattered or scattered and can be reliably captured by the strainer. , Traps that can be collected and have excellent hair-capturing and collecting functions. Moreover, because of the above-mentioned structure, the strainer has a large capacity and a large amount of hair and the like can be accommodated. Therefore, it is possible to avoid a situation in which the strainer's hair or the like is frequently piled up and cleaned frequently, and cleaning is performed for a long period of time. Is not necessary, and it is a good place for maintenance.

In addition to the above, since the strainer has a large diameter and the drainage guide pipe has a small diameter, even if a situation such as an error in assembling the drainage guide pipe or the drainage trap or a positional deviation occurs, it is easy to absorb it. Therefore, there is a great effect that the drainage guide pipe and the drainage part are easily assembled and the construction is simplified.
