Abstract
In a situation where a conventional inductive throttle sensor is used with a motor-driven throttle valve device to detect the rotation angle of a throttle shaft, plural sensor connection conductor sections for connecting a connector terminal to a circuit board terminal section are formed on the cover on one lateral surface side of a circuit board in the long-axis direction. This increases the dimension of the cover in the short-axis direction (the dimension in the direction of air flow in an intake path). Consequently, it is difficult to install the motor-driven throttle valve device and inductive throttle sensor in a narrow engine room. This problem is addressed by using a separate member to achieve electrical conduction between a stator circuit board and a conductor routed inside the cover installed over the stator circuit board in a concentrated manner on one side of the circuit board. The problem is also addressed by disposing plural electrical conduction spots in a decentralized manner and away from a protrusion provided to limit the amount of axial movement of a gear.
