PROBLEM TO BE SOLVED: To provide an oral cavity washer which can be sanitarily stored by accommodating a nozzle in a state that the nozzle is removed so as not to disturb the storing, and has no possibility to lose the nozzle. SOLUTION: A bottomed, cylindrical tank 2 whose upper surface is opened is vertically slidably attached to the outer periphery of the lower part of an oral cavity washer body 1 that washes the oral cavity by delivering water from a nozzle 22 by driving a pump 5. A nozzle accommodating portion 30 for accommodating a nozzle 22 is vertically recessed in the outer periphery of the oral cavity washer body 1. When the tank 2 is slid upward, the tank 2 can slide up to a position where the tank 2 overlaps the lower part of the nozzle accommodating portion 30.
