<P>PROBLEM TO BE SOLVED: To provide an exhaust pipe structure of a vehicle, capable of improving vibration absorption performance of an engine and improving durability of an exhaust pipe. <P>SOLUTION: This exhaust pipe structure of the vehicle has a powertrain of a structure in which a powertrain obtained by connecting an engine with a transmission is arranged so that a crankshaft is directed in a vehicle width direction, the powertrain is supported at a vehicle body by a pair of mounts above an inertia main axis and at both side parts in the vehicle width direction and a mount at a powertrain rear part, an exhaust pipe extending in a vehicle backward direction along a vehicle bottom surface is connected to an exhaust manifold, the exhaust pipe is supported at the vehicle body via an elastic member, and a flexible tube is disposed at a pipe passage held between a coupling part of the exhaust pipe to an engine and a support part of the coupling part to the nearest vehicle body. In the exhaust pipe structure, the central line of a pipe passage is curved in a crank shape in the vehicle width direction between the coupling part in that support part, and the central axis of the flexible tube is arranged so as to be directed in the vehicle width direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
