Abstract
An intake device for an internal combustion engine includes a casing, a valve, a shaft, and an actuator. The casing defines an intake passage, and the valve is contained in the casing. The shaft supports the valve, and the actuator includes a motor, a speed reduction mechanism, and a transmission mechanism which transmits torque of the motor to the shaft from a gear of the speed reduction mechanism. The transmission mechanism includes first and second connection members which are connected to the gear and the shaft respectively, and an impact absorbing member held between the first and second connection members. The first and second connection members respectively include first and second protrusions, which are alternately arranged in a rotational direction of the transmission mechanism. The impact absorbing member includes compressive deformation parts which are deformable in the rotational direction and are respectively located between adjacent first and second protrusions.
