PROBLEM TO BE SOLVED: To provide an oral cavity cleaning device in which a tube is less likely to wear. An oral cavity cleaning device (1) is connected to a main body unit (10) including a pump that discharges a cleaning liquid, a tube (80) connected to the main body unit (10) so that the discharged cleaning liquid flows, and a tube (80) so that the cleaning liquid can be discharged. Cleaning unit 100, a connecting portion 110 to which the cleaning unit 100 can be detachably attached to the main body unit 10, and a main body unit so that the tube 80 can be arranged in the state where the cleaning unit 100 is attached to the main body unit 10. The arrangement portion 40 provided in the arrangement unit 10 and the elastic member 42 provided in the arrangement portion 40 are included. The arranging portion 40 includes a recess 41 provided in the main body unit 10. The recess 41 is configured to accommodate the tube 80. The elastic member 42 is provided on the inner peripheral surface 41C of the recess 41 and the edge of the opening 41A.
