VARIABLE INTAKE DEVICE

Japanese Patent JP3777309

B2

PROBLEM TO BE SOLVED: To prevent a detector from being affected by the vibration of an actuator caused by the swing of the actuator by reducing the number of parts items and fixedly supporting the actuator on the intake path structural body side in a variable intake device in which a switchover valve is rotatably pivoted on an intake path structural body, the working member of the actuator having a working axis in a plane orthogonal to the axis of a valve stem is connected to one end of the valve stem of the switchover valve, and the rotating position of the valve stem on one end side is detected by the detector.
SOLUTION: A cover part 30a covering the connection part of the working member 28 with the valve stem 24 and connected to the intake path structural body 11 is continuously arranged on a part of an actuator case 29 integrally with each other, and a pair of bolts 33A and 33E of a plurality of bolts 33A to 33E for connecting the cover part 30a to the intake path structural body 11 are disposed through the working member 28 between the valve stem 24 and the actuator 27.
