PROBLEM TO BE SOLVED: To provide an engine in which a supercharging pressure transmission path is reduced in length. SOLUTION: A valve actuator 8 and a supercharging pressure cutoff valve case 36c are attached to an EGR valve case 7. A valve cooling water path 31 is formed in the EGR valve case 7. The heat inlet part 37 of the supercharging pressure cutoff valve case 36c faces the valve cooling water path 31. A part of the valve cooling water path 31 is formed of a through-hole 55 formed in the EGR valve case 7. One end 55a of the through-hole 55 is sealed by fitting the heat inlet part 37 of the supercharging pressure cutoff valve case 36c into one end 55a of the through-hole 55.
