摘要： In an electric pump, a vortex chamber may be formed by a clearance between an outer circumferential surface of an impeller and an inner circumferential surface of a casing. A low rigidity part may be provided to a supporting portion or a shaft, or to both of them. The low rigidity part may be formed such that while the electric pump operates, a center point of the shaft in a top view of the shaft moves along a specific line which is parallel to a tangent line of the outer circumferential surface of the impeller at the specific position and passes through the center point of the shaft while the electric pump does not operate, or moves to one of two areas divided by the specific line. The one of the two areas may he opposite to the other of the two areas that includes the specific position.

摘要： A liquid level detector may comprise an arm attached to a float, a rotator fixed to the arm, a magnet fixed to the rotator, a supporter rotatably supporting the rotator. The supporter may comprise a body housing a magnetic sensor and opposing the magnet with a clearance, a supporting portion disposed along a rotation direction of the arm on an outer circumference side of the magnet and projecting from the body toward the rotator, and a flange portion projecting from the supporting portion along an outer circumference direction at a position spaced from the body in a rotational axial direction of the arm. The rotator may comprise an engaging portion slidably disposed relative to the flange portion along the rotation direction of the arm and engaging the flange portion so as to regulate a motion of the arm in the rotational axial direction.
