Abstract: The invention is intended to simplify a default mechanism of a throttle valve opening and closing device for the purpose of improving mountability of the device to a vehicle. When a motor generate no driving forces, a throttle valve is held in a position (1) by a return spring. In this position, gaps are formed between the throttle valve and a wall surface of an intake passage. Spherical recesses are formed in parts of the wall surface of the intake passage. In a position (2) where the throttle valve is opposed to the spherical recesses, the gaps are minimized in an operating range of the throttle valve.

Abstract: Provided herein is a non-contact type rotational position sensor which is allowed to achieve intensification of parts, miniaturization, simplification of assembly, and higher accuracy. A rotor (a permanent magnet) is mounted on a rotational shaft. A Hall IC is interposed between an upper stator and a lower stator which are magnetic plates. The Hall IC is sensitive to magnetic flux density which varies according to a rotational position of the rotor. In a housing incorporating the rotor and the Hall IC is provided integrally a connector provided with an external connection terminal. Conductors for connecting external connection terminals and input/output terminals of the Hall IC are embedded into the housing by insert-molding. One ends of conductors are exposed at a fixed position where the input/output terminals are present. The terminals of the Hall IC are guided by a guide and joined to the one ends of conductors.
