In a vehicle battery unit, since a second support plate (B) and a second end plate (B) of a second battery module (B) having a plurality of battery cells () stacked are placed on top of a first support plate (A) and a first end plate (A) of a first battery module (A) having a plurality of the battery cells (), it is possible to prevent the weight of the second battery module (B) from being imposed on the battery cells () of the first battery module (A). Moreover, since it is not necessary to provide on the exterior of the first battery module (A) a member for supporting the weight of the second battery module (B), it is possible to reduce the dimensions of the first battery module (A).

A spark arrester includes a buffer plate against which exhaust gases discharged from the outlet end of a tail pipe strike directly. Upon impingement on the buffer plate, the exhaust gases become turbulent or agitated whereupon temperature distribution of the exhaust gases is made uniform. The buffer plate has a plurality of through-holes arranged to allow passage of the exhaust gases after the exhaust gases impinge against the buffer plate. After passing through the through-holes, the exhaust gases flow through a wire screen during which time sparks in the exhaust gases are caught by the wire screen. The exhaust gases are then guided downstream along a guide tube and finally released from an outlet end of the guide tube. A stream of exhaust gases discharged from the guide tube has only a limited length of high-temperature zone.
