ABSTRACT:
According to the present invention, an evaporative fuel absorbing chamber absorbingly treating evaporative fuel, a second atmospheric chamber communicating with the evaporative fuel absorbing chamber, and a first atmospheric chamber separated from the second atmospheric chamber with a partition wall are formed in a case. An upper cover for forming the upper wall of the first atmospheric chamber has a cylindrical convex portion extending inside the first atmospheric chamber. When the upper cover is fixed after inserting the bottom end of an eletromagnetic valve into a communicating hole of the partition wall, the top end of the electromagnetic valve is fastened to the cylindrical convex portion. Thus, the electromagnetic valve is prevented from being clattered, and air leakage from between the communicating hole and the electromagnetic valve can be reduced. An air passage from the electromagnetic valve to the evaporative fuel absorbing chamber is formed in the canister, so that the evaporative fuel can be prevented from leaking from the gas passage.
