  • the exhaust pipe 2 (including the first portion 4 and second portion 5 ) and the muffler 3 are supported on the lower surface of the vehicle. Exhaust from the internal combustion engine 1 is discharged to the outside via the exhaust pipe 2 , at which time the exhaust passes through the muffler 3 , the first portion 4 and the second portion 5 of the exhaust pipe.
  • the first portion 4 of the exhaust pipe is connected to the muffler 3 and extends toward the rear of the vehicle.
  • a fuel system apparatus (a fuel tank 6 in this embodiment) used to supply fuel to the internal combustion engine 1 is provided at the rear of the vehicle.
  • the first portion 4 of the exhaust pipe extends toward the fuel tank 6 .
  • a joint 7 that absorbs vertical displacement of the first portion 4 of the exhaust pipe in the event that the muffler 3 is displaced vertically is provided midway in the first portion 4 of the exhaust pipe.
  • the joint 7 that is used may be, for example, a ball joint or a flexible joint that allows free movement of the first portion 4 of the exhaust pipe about the joint 7 .
  • the second portion 5 of the exhaust pipe is connected so as to bend in the horizontal direction (up-down direction in FIG. 1A ) with respect to the first portion 4 of the exhaust pipe, and extends along the side wall 6 a of the fuel tank 6 toward the rear of the vehicle, while maintaining a prescribed clearance around the fuel tank 6 .
  • the sidewall 6 a is substantially perpendicular to the road surface, the part of the sidewall 6 a toward the front of the vehicle extends at an inclination toward the rear of the vehicle, and the part of the sidewall 6 a toward the rear of the vehicle extending straight toward the rear of the vehicle.
  • a portion of the fuel tank 6 bulges out toward the side of the vehicle and covers the top of the part of the second portion 5 of the exhaust pipe that extends along the sidewall 6 a (upward in FIG. 1A ).
  • the vehicle has a plurality of reinforcing cross members and, of these cross members, a cross member provided further toward the rear of the vehicle than the muffler 3 is used to restrict the movement of the muffler 3 toward the rear of the vehicle.
  • a pair of cross members 8 , 9 extending in the width direction of the vehicle are provided so as to sandwich the first portion 4 of the exhaust pipe therebetween from the top and bottom.
  • the cross members 8 , 9 function as restricting members.
  • the minimum distance L 1 in the vertical direction of the cross members 8 , 9 is smaller than the maximum height L 2 of the muffler 3 . That is, at least one of L 1 and L 2 may be adjusted to obtain the above-described relationship between L 1 and L 2 .
  • the usual distance L 3 in the longitudinal direction of the vehicle between the part of the cross members 8 , 9 that catches the muffler 3 and the part of the muffler 3 that comes into contact with the cross members 8 , 9 is smaller than the minimum distance L 4 between the second portion 5 of the exhaust pipe and the sidewall 6 a of the fuel tank 6 when the exhaust pipe is mounted abroad the vehicle. That is, at least one of L 3 and L 4 may be adjusted so as to obtain the above-noted relationship between L 3 and L 4 .
  • the muffler 3 comes into contact with the cross members 8 , 9 shown in the same drawings, thereby restricting the muffler 3 from further movement toward the rear of the vehicle, which prevents interference with the fuel tank 6 by the second portion 5 of the exhaust pipe.
  • the muffler When a front-end collision occurs in a vehicle, the muffler might be displaced not only toward the rear of the vehicle, but also vertically. For example, when the muffler 3 is displaced upwardly as indicated by the arrow in FIG. 3 , along with this displacement that the first portion 4 of the exhaust pipe is also displaced upwardly. Stated differently, the first portion 4 of the exhaust pipe approaches the part of the fuel tank 6 that bulges upward above the first portion 4 of the exhaust pipe (refer to FIG. 1A ). With regard to the displacement of the first portion 4 of the exhaust pipe, however, when the muffler 3 is displaced upward, the bending of the joint 7 , as shown in FIG. 3 , restricts the first portion 4 of the exhaust pipe.
  • the embodiment described in detail above achieves a number of effects.
  • the first effect is that, when the vehicle is subjected to a front-end collision and the overall exhaust apparatus is displaced toward the rear of the vehicle, the muffler 3 makes contact with the cross members 8 , 9 before making contact with the side wall 6 a , further displacement of the muffler 3 toward the rear of the vehicle being restricted, which makes it possible to avoid interference by the second portion 5 of the exhaust pipe with the fuel tank 6 .
  • the second effect is that, because the cross members 8 , 9 restrict the displacement of the muffler 3 toward the rear of the vehicle, an additional restricting member need not be provided, thereby avoiding the additional cost associated with providing an additional restricting member.
  • the third effect is achieved by using a pair of cross members 8 , 9 as cross members that restrict the displacement of the muffler 3 toward the rear of the vehicle, the cross members 8 , 9 sandwiching from the top and bottom the first portion 4 of the exhaust pipe disposed to the rear of the vehicle from the muffler 3 .
  • the distance L 1 between the cross members 8 , 9 is set to a value that is smaller than the height L 2 of the muffler 3 .
  • the fourth effect is that, in the event of a front-end collision, when the muffler 3 is displaced not only toward the rear of the vehicle but also vertically, the accompanying vertical displacement of the first portion 4 of the exhaust pipe is absorbed by the joint 7 . This makes it possible to avoid interference of the first portion 4 of the exhaust pipe with the fuel tank 6 by the vertical displacement of the first portion 4 of the exhaust pipe.
  • a part that is more easily bendable than another part of the exhaust pipe may be provided midway in the first exhaust pipe.
  • a bending part 4 a that is formed like a bellows may form as the easily bendable part. In this case; the same effect of the above described forth effect will be obtained.
  • the first portion 4 of the exhaust pipe may be, for example, disposed between a part other than the cross member provided on the vehicle floor 10 and the cross members 8 , 9 , and the distance between the part and the cross members in the up-down direction may be set to a value that is smaller than the height L 2 of the muffler 3 . In this case, the same effect above described third effect will be also obtained.
  • an additional restricting member may be provided in the vehicle.
