A heat blocking member is fixed to a part of an engine in order to protect a signal wire or the like situated nearby from heat generated by the exhaust recirculation device. The exhaust recirculation device comprises an exhaust recirculation passage connecting an intake passage and an exhaust passage of the engine, a valve for opening and closing the exhaust recirculation passage and a drive mechanism for opening the valve. The valve is normally closed. By forming a specific part of the drive mechanism in a one-piece construction In with the heat blocking member, exhaust recirculation is prevented from taking place when the heat blocking member is not attached.
