Abstract: An actuator drives a boost pressure control valve of a supercharger of an engine and includes an electric motor, an output shaft, a speed reducer, a rotational angle sensor and a housing. The speed reducer includes three pairs of metal gears and is configured to reduce a speed of rotation outputted from the electric motor and transmit the rotation to the output shaft. The rotational angle sensor includes a magnetic circuit device and a sensing device and senses a rotational angle of the output shaft. The housing receives the metal gears and the magnetic circuit device in a common space and supports the output shaft. In an installed state of the actuator where the actuator is installed to the engine, a meshing portion of the metal gears is located on a lower side of a magnetic circuit lowest point in the gravity direction.

Abstract: In a valve drive apparatus, which drives a first valve and a second valve of a supercharger, a first rod is rotatably connected to a first valve lever shaft at one end part thereof to drive the first valve and is connected to a shaft at the other end part thereof, and a second rod is rotatably connected to a second valve lever shaft at one end part thereof to drive the second valve and is connected to a second member at the other end part thereof. A spring is placed between a first engaging part of the first member and a second engaging part of the second member and urges the first member and the second member to urge a first contact part of the first member and a second contact part of the second member toward each other.

Abstract: A first rod is rotatably connected to a first drive lever shaft and a first valve lever shaft. A second rod is rotatably connected to a second drive lever shaft and a second valve lever shaft. A first predetermined shape portion is formed at a location, which is spaced from an axis of an output shaft by a predetermined distance. A second predetermined shape portion is formed in a second drive lever and is contactable with the first predetermined shape portion. A spring is placed between the actuator and the second drive lever and urges the second drive lever in a predetermined direction, which coincides with a closing direction of a second valve and an approaching direction of the second predetermined shape portion toward the first predetermined shape portion.

Abstract: An output gear includes a fixing portion, which is joined to a surface-processed portion of an output shaft, and a connecting portion that connects between a toothed portion of the output gear and the fixing portion. A length, which is measured from a center of a boundary surface between the connecting portion and the fixing portion in an axial direction of an axis of the output shaft to one end part of a joint between the surface-processed portion and the fixing portion on a linkage mechanism side along the joint, is indicated by L1. A length, which is measured from the center of the boundary surface to an opposite end part of the joint that is opposite to the linkage mechanism in the axial direction, is indicated by L2. A relationship of L1>L2 is satisfied.
