Abstract

See full text

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.
