A drainage connector communicates between a drain outlet of a toilet drainage path connected to a toilet bowl and a connecting port of a drain conduit led into a room equipped with a toilet body. The drainage connector includes a casing formed with a flow inlet connected to the drain outlet and a flow outlet connected to the port, and piping disposed in the casing. The piping has an upstream piping having an upstream opening communicating with the flow inlet and forming a downward flow path when the drain outlet communicates with the port and a downstream piping connected to the upstream piping and having a downstream opening open to the casing in a lateral direction along an inner surface of the casing so that flush water flows out in the lateral direction. The downstream piping forms an upward flow path when the drain outlet communicates with the port.

An air suction device for a toilet drain passage includes a suction tank partitioned by a diaphragm into an upper chamber and a lower chamber communicating with the passage, and an electromagnetic drive device moving the diaphragm upward. The drive device has a cylindrical case body installed away from the tank, a moving member housed in the case body so as to be vertically movable, and a moving device located on a lower end of the case body. The moving device has a casing and an actuator assembled in the casing to move the moving member. The case body has a first airtight chamber surrounded by the moving member and the moving device. The first airtight chamber has a cubic capacity changed by movement of the moving member and communicates with the first chamber. The first airtight chamber sucks air in the first chamber to move the diaphragm upward.
