Abstract: An inner ring of a bearing is fixed to an outer periphery of a central portion of a shaft between a pair of facing sections. An outer ring of the bearing is fixed to a hole wall surface of a shaft accommodation recess. A spring is accommodated between one of the pair of facing sections and the bearing in a state where the spring is compressed in a rotational axis direction of a pin rod for pressing the bearing against the other one of the pair of facing sections. Thus, defects such as galling or friction between a casing and rotary valves can be inhibited. Accordingly, occurrence of wear or an abnormal noise between the casing and the rotary valves can be inhibited.

Abstract: An air intake device for an engine includes a duct having therein a first air flow passage, a housing having therein a second air flow passage, a rotary valve having a valve plate. A block of the housing, which conducts intake air to an intake port of a cylinder head, has a circular opposed surface that follows a shape of a curved surface portion of the valve plate. Moreover, the block of the housing has a protrusion that protrudes toward an upstream side of the second air flow passage in an air flow direction so as to contact a duct protrusion of the duct. Therefore, a localized flow of the intake air, which has flowed into the second air flow passage from an opening of the first air flow passage, can be restrained from spreading, and a flow rate of the localized flow can be restrained from slowing down.

Abstract: A magnetic sensing surface of a stroke sensor is placed in an angular range between a first imaginary line and a second imaginary line. The first imaginary line is an imaginary line that coincides with a center line between first and second magnets of a magnetic movable body when a wastegate valve is placed to have a full close degree of the wastegate valve. The second imaginary line is an imaginary line that coincides with the center line between the first and second magnets when the wastegate valve is placed to have a half degree between the full close degree and a full open degree of the wastegate valve.
