Provided is an exhaust gas recirculation device of a vehicle motor, and the condensate water is not easy to freeze in the device in cold weather. An exhaust manifold (16) is provided with a horizontal divided manifold portion (27) and a vertical manifold portion (28). An exhaust gas cooler (29) is configured in the space surrounded by the exhaust manifold (16) and a motor (2), and the upper part of theexhaust gas cooler is coated by the horizontal divided manifold portion (27) and the front part is coated by the vertical manifold portion (28). An exhaust pipe (22) and theexhaust gas cooler (29) are communicated through an upstream side exhaust gas recirculation pipe (33). The exhaust gas cooler (29) and a cylinder cover (4) are communicated by a downstream side exhaust gas recirculation pipe (34). The exhaust gas inlet portion (35) and the exhaust gas outlet portion (36) of the exhaust gas cooler (29) are on the same height with the exhaust joining portion (21) of the exhaust manifold (16). The exhaust gas inlet portion (35) is configured in a first space portion (37). Theexhaust gas outlet portion (36) is configured in a second space portion (38). |
