ABSTRACT:
A fuel vapor treatment device for an automotive vehicle includes a casing having a charge port connected to a fuel tank, a purge port connected to an intake side of an engine, and an atmospheric air port through which atmospheric air is introduced. Fuel vapor adsorbing material is filled in the casing. A filter is disposed in the casing and between the atmospheric air port and the fuel vapor adsorbing material to trap dust contained in atmospheric air. A baffle plate is disposed in the casing and between the atmospheric air port and the filter to change flow of atmospheric air introduced through the atmospheric air port into a generally radial direction. Additionally, an annular space is formed around the baffle plate so that atmospheric air from the baffle plate flows through the annular space to the filter.
