PROBLEM TO BE SOLVED: To provide a new bathtub water injector which achieves injection over a wider range and conservation of water without electric drivers. SOLUTION: An injection body 10 is incorporated into a spiral chamber 15 so as to be allowed to oscillate when a force receiving part 21 takes an attitude of being inclined in the spiral chamber 15 with an injection port 11 outside the spiral chamber 15 so that water is supplied to the spiral chamber 15 from the tangential direction thereof. A difference in flow velocity is generated around the force receiving part 21 in a swirl thus generated in the spiral chamber 15 to exert a force, generated based on the difference in the flow velocity, on the force receiving part 21. This causes the force receiving part 21 to take the attitude of being inclined in the spiral chamber 15 to make the injection body 10 oscillate thereby injecting bathtub water in the spiral chamber 15 from the injection port 11.
