Throttle Device

A throttle device includes a coil spring that has a first spring part, a second spring part, and an intermediate hook connecting the first spring part to the second spring part for biasing a throttle valve. The first spring part is engaged with a rotation member coupled to a throttle shaft. The second spring part is engaged with a throttle body. The intermediate hook is configured to engage with a first stopper formed on the rotation member and a second stopper formed on the throttle body. The intermediate hook includes a first part on the first spring part side and a second part on the second spring part side. When the intermediate hook is engaged with the first stopper or the second stopper, the first part abuts on the first stopper or the second stopper.
