Vehicle body mounting configuration including exhaust system heat exchanger

A vehicle body mounting configuration including an exhaust system heat exchanger, comprising:

• the exhaust system heat exchanger, which is extended in a vehicle front-rear direction so as to allow heat exchange to take place between exhaust gas flowing through an exhaust gas flow path and a cooling medium flowing through a cooling medium flow path;
• a tunnel portion which opens downward in a vehicle vertical direction and extends in the vehicle front-rear direction and in which at least part of the exhaust system heat exchanger is placed inside;
• a cross member which extends in a vehicle width direction and which bridges wall portions of the tunnel portion which face each other in the vehicle width direction at an upper side in the vehicle vertical direction relative to a portion of the exhaust system heat exchanger which lies outside, in a longitudinal direction, of a range where the cooling medium flow path is placed;
• and
• a suspending support unit which is fixed at one end to a portion of the exhaust system heat exchanger at a lower side in the vehicle vertical direction of the cross member, and is fixed at an other end to the cross member so as to support the exhaust system heat exchanger on the cross member in a suspending fashion, wherein
• the exhaust system heat exchanger is disposed in such a manner that a lowermost portion in the vehicle vertical direction is positioned at a first end in a longitudinal direction,
• the vehicle body mounting configuration further comprises a fuel tank which is disposed closer to the first end than to a central portion in the longitudinal direction of the exhaust system heat exchanger and is positioned to project farther downward in the vehicle vertical direction than the lowermost portion of the exhaust system heat exchanger in the vehicle vertical direction,
• the exhaust system heat exchanger is disposed inclined relative to the vehicle front-rear direction in such a manner that the first end in the longitudinal direction is positioned farther downward in the vehicle vertical direction than a second end in the longitudinal direction, and
• the second end in the longitudinal direction is disposed at an upper side of a vehicle body framework which extends in the vehicle width direction.
