<P>PROBLEM TO BE SOLVED: To easily secure the lowest height from the ground surface of a car body, even when a catalyst is arranged below a crankcase of an engine. <P>SOLUTION: A front side catalyst 40 is arranged below the crankcase 21 of the engine 20. The front side catalyst 40 is formed in a flat shape smaller than a width dimension in the lateral direction on a height dimension in its vertical direction. Among an exhaust pipe 30, under surfaces 33A and 34A of a third pipe 33 and a fourth pipe 34 arranged below the crankcase 21, are arranged so as to become substantially flush with an under surface 40A of the front side catalyst 40. <P>COPYRIGHT: (C)2008,JPO&INPIT |
