## Abstract

A rear panel is provided in rear of a connecting wall rising upwardly from a rear end of a front floor panel, and a fuel tank supported within a subframe is disposed beneath a lower surface of the rear floor panel. A gas fume absorbing canister and a muffler are juxtaposed in a lateral direction of a vehicle body in a space which is surrounded by a rear surface of a middle cross-member secured to a rear surface of the connecting wall, a front surface of the fuel tank and the lower surface of the rear floor panel. Thus, it is possible to shorten a purge passage connected from the canister to an engine, to protect the canister from collision against a stepping stone or the like, to insure the volume of a trunk room and to enhance the purging efficiency of the canister utilizing a heat of the muffler by reasonably disposing the canister at a rear portion of the vehicle body.
