A branching tool serving as a check valve incorporated in a cleaner device includes: a main unit provided with an inflow channel and a first outflow channel; a sealing member that allows a flow of cleaning fluid from the inflow channel to the first outflow channel when the cleaner device is in operation and that is formed to seal a backflow of the cleaning fluid from the first outflow channel to the inflow channel when the cleaner device is not in operation; and a lid member that is combined with the main unit so as to form a housing chamber for the sealing member. The lid member has a communication hole that allows the housing chamber to communicate with the outside. The lid member or the main unit is provided with a water receiving recess arranged around the communication hole.
