<p><P>PROBLEM TO BE SOLVED: To accommodate enlargement of an exhaust emission control device. <P>SOLUTION: A second casing 14 storing an SCR catalyst is arranged obliquely above a casing 12 to be superposed on the first casing 12 storing a DPF when viewed in a vehicle width direction and from above, and a communication pipe 16 allowing the distal ends of the casings to communicate with each other is installed lateral to the casing 14 and above the casing 12. A support frame 18 supporting the casings 12, 14 includes: a fixed portion 18a which is fixed to the outer surface of a frame 10 outward of vehicle width to extend in a vertical direction, and which has a lower end extending inward and downward of the vehicle width and subsequently extending downward; and an overhang portion 18b extending outward of the vehicle width not to project upward beyond the upper surface of the frame 10. The end of the overhang portion 18b supports the casing 14 in the portion of the peripheral surface of the upper half side of the casing 14 facing the inward of the vehicle width, and the lower end of the fixed portion 18a supports the casing 12 in the portion of the peripheral surface of the lower half side of the casing 12 facing the inward of the vehicle width. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
