Abstract
PURPOSE: To develope good fuel vapor adsorbing capacity as well as to prevent fuel vapor from being bypassed to a mixed gas discharge port by introducing the fuel vapor into a high density activated carbon fiber paper contained in an adsorbent layer from the entire surface thereof to a thickness direction thereof so as to traverse therethrough.
CONSTITUTION: Fuel vapor is at first flowed into a low density activated carbon fiber paper 15b having a hermitically sealed part 15c provided only to the lower end flange thereof to be adsorbed thereby. This vapor is further flowed through a high density activated carbon fiber paper 15a from the entire surface thereof so as to traverse the same therethrough and flowed into a low density activated carbon fiber paper 15b having a hermetically sealed part 15c provided only to the upper end flange thereof. On the other hand, when the throttle valve of an air sucking pipe is opened as in time when an internal combustion engine is operated and a vehicle is run, air introduced into a container 1 from an air introducing port 10a by negative pressure to desorb the fuel vapor adsorbed by the adsorbent layer 15 and the resulting mixed gas is supplied to the air sucking pipe through a mixed gas discharge port 7 and a mixed gas discharge pipe 4.
