Problem has occurred. Also, in this drain trap, the thin wall portion for breaking the tubular portion for connecting the drain pipe is broken with a striking force to open the drain port. Therefore, if the drainage pipe connection cylinder on the peripheral wall is opened by mistake, the drainage pipe connection cylinder on the bottom wall may be opened by mistake. There is. Further, during the transportation of the product, there is a possibility that the thin portion for breaking may be damaged unexpectedly. In such a case, there was a defect that the drain trap itself could not be used. By the way, the two drain pipe connecting cylinders were connected from the beginning to the trap body, and the drain pipe connecting cylinder was threaded on the inner peripheral surface, and a threaded rod shaft (plug) was formed on the outer peripheral surface separately. A screwing method in which one of the drain pipe connecting cylinders is closed by screwing is conceivable. However, in the threaded structure of the rod shaft, the material of the drain pipe connecting cylinder is limited due to the necessity of thread cutting, and the product is not expensive due to the thread cutting work, and it is originally a perfect There are many disadvantages, such as the possibility of water leakage from the screwing gap that requires sealing water, and in practice this cannot be adopted.

The present invention solves the above problems, allows a plurality of drain pipe connecting cylinders to be selectively used, is free from the disadvantages due to selection errors, and has no fear of water leakage. The purpose is to provide.

[0005]

[Means and Actions for Solving the Problems]

 In order to achieve this purpose, the drain trap of this invention has the following configuration. The drain trap shall have a cylindrical trap body with an upper opening and a drain port that projects from the peripheral wall and bottom wall, respectively, and selectively press fit into the peripheral wall drain port and the bottom wall drain port. In addition, it is characterized by comprising a drainage port closing push-in sealing body that selectively closes one of the drainage port portions.

In the drain trap having such a configuration, the drain port closing push-in sealing body is selectively fitted to the cylindrical drain port portions protruding from the peripheral wall and the bottom wall of the tubular trap body. By doing so, either one of the drain ports is closed. Therefore, simply select the drainage port that matches the pipe axis of the sewage branch pipe and press the drainage port closing sealing body into the other drainage port to insert the drainage port sealing part into the wastewater drainage port. It can be closed. Further, even if the tubular drainage port portion that coincides with the pipe axial direction of the drainage pipe is closed with a sealing body, the sealing body can be removed and reattached when a closing error is noticed. Therefore, it is possible to eliminate the disadvantage that the drainage port itself cannot be used because the drainage port cannot be connected to the sewer pipe by accidentally opening the drainage port that does not coincide with the axial direction of the drainage pipe.
