PURPOSE:To enable water level to be surely detected even if it is inclined by providing a water level sensor having one L-shaped end and parallel to the water level in anatomizing tube provided on the bottom with an atomizing oscillator. CONSTITUTION:An atomizing tube 4 is provided on the bottom of water with a supersonic oscillator 6 which in turn is provided horizontally on the upper portion with a water level sensor 12. This water level sensor 12 has a L-shaped sensing portion 12a and a straight sensing portion 12b vertically closely opposed to each other. Thus, when a vehicle is inclined to the front and rear sides, the front and rear end sides of sensing portions 12a, 12b contact water 5. Also, when the vehicle is inclined left and right, the bent end of sensing portion 12a contacts water 5. Thus, even if the water level in the atomizing tube 4 is inclined by the inclination of vehicle, the presence of water can be detected by either of sensing portions of water level sensor 12 so that the water level can be surely detected. |
