A rotor having magnets composed of rare-earth magnets is rotatably disposed inside an exterior casing, a penetrating aperture is disposed through a first end of the exterior casing relative to a direction of a motor central axis, and a filter is disposed so as to cover the penetrating aperture from a second end of the exterior casing relative to the direction of the motor central axis. A shaft is mounted to a bush by screwing an external thread portion into an internal thread portion. An operating member is mounted integrally onto a second end portion of the shaft projecting outward from a penetrating aperture in a housing. A rotation-regulating projection portion of a guide member fixed to the shaft is fitted loosely into a guide groove disposed so as to extend along an inner wall surface of a central aperture of the housing in the direction of the motor central axis.

Actuator for operating a transmission control valve of an automatic transmission apparatus

An intake air throttle valve device is capable of statically determining the opening of a throttle valve by balance between a driving force from a motor and an elastic force from an elastic member, thus making it possible to prevent the occurrence of a range in which it is impossible to control the opening of the throttle valve in accordance with the amount of electric power supplied to the motor. The intake air throttle valve device of the present invention is provided, in an intermediate portion of the elastic member with a load applying element for causing the elastic member to generate a force to oppose the force of a throttle gear thereby to apply a load to the throttle gear. The load applying element includes a third engagement portion, a first abutment portion and a second abutment portion.

Intake air throttle valve device

In an intake air rate controlling device including a throttle body, forming an air-intake passage, and a plate-like throttle valve, rotatably supported by the throttle body through a throttle shaft, wherein an intake air rate supplied to an internal combustion engine is controlled by a rotation of the throttle valve, and air-flow controlling means is located on an upper stream side or a lower stream side of the throttle valve for suppressing a variation of a torque, effecting on the throttle valve by a hydrodynamic force generated by an intake air, whereby excellent durability, excellent reliability, and high performances are obtainable.

Intake air rate controlling device for an internal combustion engine

In an intake air quantity controlling device for a combustion engine, a supporting portion of a bearing,for a valve shaft,having a choke valve,, rotatably operated in an intake air passage,, a supporting portion of a shaft of an intermediate gear,, and a reference hole for a shaft of a rotor,fabricating a motor are formed in a metallic plate,, whereby the intake air quantity controlling device has a high dimensional accuracy and a high strength.
