PROBLEM TO BE SOLVED: To provide a flow channel switchgear capable of suppressing deviation of water pressure distribution in the surroundings of a main valve body.SOLUTION: The present invention provides a flow channel switchgear which starts water supply to a toilet bowl by receiving an instruction for starting the water supply, autonomously stops the water supply by satisfying predetermined conditions, comprises: a primary side flow channel communicating with a water supply source; a secondary side flow channel orthogonal to the primary side flow channel and communicating with the toilet bowl which is the water supply source; and a main valve having a main valve body and a main valve seat for switching a flow channel between the primary side flow channel and the secondary side flow channel. The flow channel switchgear drives the main valve body in a direction separating from the secondary side flow channel, supplies washing water for washing the toilet bowl to the secondary side flow channel by separating the main valve body from the main valve seat when the washing water is supplied to the toilet bowl, and comprises a water pressure adjustment member having a water guide part for guiding the washing water in order to adjust the deviation of water pressure in the surroundings of the main valve body. |
