    Abstract: A throttle valve device includes a coil spring arranged in a body between a valve gear and a valve and having a spring end extending radially outward. A first guide covers an end of the coil spring and includes a first guide hook that contacts the spring end. A body hook in the body is capable of contacting a tip end part of the first guide hook. A valve gear hook in the valve gear is capable of contacting a base end part of the first guide hook. The first guide hook has a protrusion protruding toward the spring end between the tip end part and the base end part. The first guide hook is deformable by receiving the spring force at the protrusion as an effort while a fulcrum is at a contact between the first guide hook and the body hook or the valve gear hook.

    Abstract: A first integrated circuit includes a first voltage output circuit for outputting a voltage, which proportionally increases in correspondence to an angular position of a throttle valve, a first protective resistor, a first output terminal connected to the first protective resistor, and a first abnormality detection circuit for outputting a first abnormality detection signal based on a voltage produced by the first protective resistor. A second integrated circuit is configured similarly to the first integrated circuit by a second voltage output circuit, a second protective resistor, a second output terminal, and a second abnormality detection circuit.

    Abstract: A high-side output transistor and a low-side output transistor of an output circuit control voltages of conductors, which connect a power supply terminal and ground, and outputs a voltage signal to an output terminal through an output conductor. A voltage output circuit detects a voltage applied to the high-side output transistor based on a potential difference of a first resistor provided closer to the output terminal side. A comparator circuit outputs a signal to turn off a first switch and a second switch provided in the conductors, when the output voltage of the voltage output circuit exceeds a reference voltage Vr.
