Abstract: In a liquid level detector, a first clearance may expand as at least one of a rotator and a supporter swells with a target liquid. The first clearance may be a smaller one of an inner clearance between an inner circumference side of a first guide rail and an inner circumference portion and an outer clearance between an outer circumference side of the first guide rail and the outer circumference portion, in a state where the rotator and the supporter are not swelled with the target liquid. A second clearance may contract to become smaller than the first clearance as at least one of the rotator and the supporter swells with the target liquid. The second clearance may be a larger one of the inner clearance and the outer clearance in the state where the rotator and the supporter are not swelled with the target liquid.

The supporter may include a body, and an outer circumference wall disposed along a rotation direction of the arm on an outer circumference side of the magnet. The rotator may include a cover covering an end part of the outer circumference wall, and an opposing wall opposing at least one of an inner circumference surface and an outer circumference surface of the outer circumference wall. A first clearance between the supporter and the magnet may communicate with an outer space via a second clearance between the outer circumference wall and the cover and a third clearance between the outer circumference wall and the opposing wall. The first clearance may be larger than at least one of the second clearance and the third clearance.

Abstract: A rotational position sensor includes a rotor substrate and a stator substrate placed to face each other to detect rotational displacement of the rotor substrate. The rotor substrate is formed with an excitation coil in a meandering pattern on an outer circumferential side and a rotor-side rotary transformer on an inner circumferential side. The stator substrate is formed with four detection coils in a meandering pattern on an outer circumferential side and a stator-side rotary transformer on an inner circumferential side. The four detection coils are arranged in a circumferential direction without overlapping each other. The detection coils are displaced from each other by 360°/8. The rotational position sensor includes a high frequency excitation circuit for applying a high frequency signal to the excitation coil through the rotor-side rotary transformer and the rotor-side rotary transformer to excite the excitation coil.
