Abstract: A throttle valve device includes a body, a valve, a motor, and a cover. The body defines a passage, a motor space, and a connecting portion that connects the motor space to the passage. The motor includes a motor yoke made of a magnetic material, a plurality of magnets that are arranged on an inner circumferential surface of the motor yoke. The plurality of magnets are magnetized in a state where the motor yoke is disposed in the motor space of the body. The plurality of magnets are arranged in a circumferential direction in the motor yoke with a space. The connecting portion is aligned with the space between the plurality of magnets in a radial direction of the motor yoke.

Abstract: A housing defines a bore in a tubular shape to draw intake air to an engine. A shaft is supported rotationally relative to the housing. A valve is located in the bore and affixed to the shaft. An electric actuator is configured to rotate one end of the shaft. A load generating unit is configured to apply a biasing load onto the shaft from the one end of the shaft toward the bore in a high-temperature state in which a temperature is higher than a predetermined temperature.

Abstract: A surface of a bearing member on a flow passage forming chamber-side is disposed to be exposed to the chamber. The bearing member includes a contact part, with which a side surface of a butterfly valve that is opposed to the bearing member is in contact, on at least a part of the surface of the bearing member on the chamber-side. The bearing member is a radial ball bearing and includes an outer bearing ring that is fitted to an inner periphery of a shaft hole, so that its axial displacement relative to a body is restricted, an inner bearing ring that is fitted on an outer periphery of a rotation shaft radially inward of the outer bearing ring, and a rolling element disposed between the outer bearing ring and the inner bearing ring. The contact part is provided on a surface of the inner bearing ring on the chamber-side.

Abstract: An electric actuator includes an electric motor, a gear deceleration device, a housing, and a motor attachment plate. The electric motor is configured to convert electric power into rotation output. The gear deceleration device is configured to decelerate the rotation output of the electric motor. The electric motor and the gear deceleration device are attached to the housing. The motor attachment plate is provided for the electric motor and is fixed to the housing. A first positioning hole, which is formed through the motor attachment plate, and a second positioning hole, which is provided for the housing coincide with each other in a state where the electric motor is attached to the housing.
