PROBLEM TO BE SOLVED: To prevent freezing of blow-by gas by heating a blow-by gas recirculation pipe by heat from an exhaust manifold during cold weather and also preventing cooling by traveling wind, and to achieve inexpensiveness by simplifying a pipe structure or the like, in a blow-by gas recirculation device. SOLUTION: The blow-by gas recirculation pipe (26) is formed with a heat receiving section (34) receiving heat from the exhaust manifold (15) in the vicinity of the end (15E) of the exhaust manifold (15). The heat receiving section (34) of the blow-by gas recirculation pipe (26) and a passage section (35) leading from the heat receiving section (34) to a blow-by gas inlet (29) are arranged behind an intake hose (20) in a vehicle longitudinal direction (X).
