An evaporated fuel discharge preventing apparatus, in order to sufficiently adsorb and collect an evaporated fuel generated in an intake air passage at a time when an engine stops, and to prevent an engine performance from being reduced by reducing an intake air resistance in an evaporated fuel adsorbing portion at a time when the engine is driven, has an adsorbing device arranged in a passage between an evaporated fuel generating portion and an air cleaner element, and, the adsorbing device is formed by an intake air passage portion laterally arranged within the device penetratingly and communicated with the passage at both ends, an adsorbent layer arranged on an outer periphery of the intake air passage portion, and a member covering an outer surface in a non-ventilating state except a side of the intake air passage portion in the adsorbent layer, and an inner diameter of the intake air passage portion of the adsorbing device is set to be substantially equal to or more than an inner diameter of the intake air passage.
