Abstract

A throttle device includes a rotating member coupled to a throttle shaft and rotated by a drive source, and a coil spring interposed between a throttle body and the rotating member and configured to bias the throttle valve toward a default position. The coil spring has a first spring portion, a second spring portion, and an intermediate hook portion for connecting the first spring portion and the second spring portion. The rotating member includes an inner periphery supporting portion that supports an inner peripheral side of the first spring portion, an outer periphery supporting portion that supports an outer peripheral side of the first spring portion, and a blocking structure for preventing the first spring portion from being fitted to an outside of the outer periphery supporting portion when assembling the coil spring.
