Claims

[Scope of utility model registration request]

A valve body that controls the amount of air passing through the bypass intake passage that connects the upstream and downstream sides of the intake throttle valve, and a rotation that drives the valve body so that a target idle speed corresponding to the engine operating state is obtained. It has a type electromagnetic drive device and a temperature sensing part that operates according to the ambient temperature and engine warm-up state.
A temperature-sensitive regulating means for regulating the amount of operation of the valve body by the rotary electromagnetic drive device within a predetermined range according to the amount of operation of the temperature-sensing section, and a cooling medium for cooling a predetermined portion of the engine are introduced. and a cooling medium chamber in which at least a temperature-sensing section of the temperature-sensing regulating means is housed.
