Abstract: A rotation driving device includes a motor provided in a housing, a planetary gear reducer connected to the motor coaxially with the motor, an output shaft connected to an end reduction member of the planetary gear reducer coaxially with the end reduction member, and a rotation detector located at the same position as the end reduction member in an axial direction of the planetary gear reducer and located at a different position from a center axis of the end reduction member in a radial direction of the planetary gear reducer, the rotation detector being capable of detecting a degree of rotation of the end reduction member. Accordingly, the rotation driving device can be made to be smaller and compact in the axial direction.

Abstract: In an exhaust system for an internal combustion engine, an output member is configured to transmit power generated by a motor to a valving element via a valve stem. An output shaft is disposed on a rotation central axis of an output gear and coupled with the output gear to be rotatable integrally therewith. A follower is disposed eccentrically relative to a rotation central axis of the output shaft and connected to the output shaft to be rotatable integrally therewith. A first accommodating chamber accommodates at least the valve stem and the follower. A second accommodating chamber accommodates at least the motor and the output gear. A housing includes a housing wall that divides the first chamber from the second chamber. The housing wall includes a first bearing slidably supporting the output shaft in its rotation direction, and a cylindrical first bearing holder holding outer periphery of the first bearing.

Abstract: A turbocharger device includes a turbine and a compressor coaxially connected to each other. The turbine is equipped to an exhaust system of an engine. The compressor is equipped to an intake air system of the engine. An EGR device recirculates a part of exhaust gas as EGR gas from a downstream of the turbine to an upstream of the compressor. The EGR device includes an EGR cooler, which is to cool EGR gas, and an EGR valve unit, which is to control a flow of EGR gas according to an opening of an EGR valve. The EGR cooler, the EGR valve unit, and the turbocharger device are screwed to a common bracket and are positioned relative to each other.
