Description of the Related Art Conventionally, devices that generate drainage by use (hereinafter referred to as "drainage devices"), such as indoor bathrooms, washing machines, and waterproof pans used therein, have been produced by using the devices. To treat wastewater to the sewage side,
Drainage equipment is used. There are various types of drainage equipment,
As shown in FIG. 7, there is a drainage device that simply connects a drainage device to a drainage pipe connected to a sewage side or the like, as in a drainage device called a drainage elbow. Equipped with a function to prevent odors and pests from going back inside the drainage device and entering indoors from the drainage device.
There is also a drainage device called a drainage trap. There are several types of drain traps.

排水トラップを使った浴室構造を提供するものである。By the way, the flow path of the drain water flowing in the drain trap as shown in FIG. 7 has a larger area than a simple drain device such as a drain elbow also shown in FIG. Since the water flows in a narrow place while changing the direction many times, the drainage performance deteriorates as much as the flow path of the drainage becomes complicated. For this reason, if a large amount of drainage flows from the drainage outlet of the drainage trap and the drainage cannot be discharged from the drainage at a sufficient speed, the excess wastewater is urged by the drainage force at the time of drainage, and from the deodorizing bowl portion. There is a problem in that a large amount of water flows into the drainage device connected to the branch pipe portion and overflows into the drainage device connected to the drainage device, causing a phenomenon called backflow. As a method for preventing this, there is known a method of using a movable member such as a float or a hinge to arrange a check valve or the like on a branch pipe portion or the like that restricts the flow of drainage to only one direction. When such a check valve is used, the number of members and the assembly labor increase by the check valve, and it becomes impossible to provide a product at low cost. In addition, while using the drainage system for a long time, the movable part is deteriorated and damaged, or dust adheres to it, and it cannot move, and the function of preventing backflow is lost or the valve is closed. There are also problems such as the inability to drain water. The present invention has been made in view of the above-mentioned problems, and a drain trap connected to a drainage device through a branch pipe portion and not using a check valve or the like by a movable member such as a float or hinge is provided. The present invention provides a drain trap that does not cause backflow on the drain device side connected to the branch pipe even if a large amount of drain water is discharged, and a bathroom structure using such a drain trap.
