Abstract:
In this throttle valve device, when a rotating body (525, 6525) is oriented at a default position (Ld) due to the absence of a drive force, a first hook part (531) and a second hook part (532) each engage with a fixed engagement part (330) and/or a movable engagement part (528), and when the rotating body (525, 6525) is rotated from the default position (Ld) due to the generation of a drive force, the first hook part (531) and the second hook part (532) respectively engage with one or the other of the fixed engagement part (330) and the movable engagement part (528). On a radially inward side of a first winding part (535) of a coil part (533) on the first hook part (531) side and/or a first winding part (536) thereof on the second hook part (532) side, a guide body (526, 2526, 3526, 4526, 5526, 6526, 7526) is provided with a relief part (524, 2524, 3524, 4524, 5524, 7524) that lets the coil part (533) escape.
