A liquid-level detecting structure includes a housing disposed in a tank in proximity to a wall surface of the tank, a float disposed inside the housing and adapted to be moved by the liquid which has entered the housing, and a passage provided for introducing the liquid into the housing and having an opening facing the wall surface of the tank. When acceleration has acted toward the wall surface of the tank with the liquid level being close to a minimum level, the liquid is biased toward the wall surface. Accordingly, the opening of the passage is immersed in the liquid, preventing the float from being further lowered. Meanwhile, when acceleration has acted toward a wall surface opposite to the adjacent wall surface, this acceleration is oriented in an opposite direction to the direction in which the liquid flows out of the opening of the passage, so that the liquid in the housing is prevented from flowing out of the passage.
