Abstract
A fuel vapor adsorption filter includes a fuel vapor adsorption agent; a filter body containing the fuel vapor adsorption agent therein, and a frame formed to surround the filter body. The frame is adapted to be mounted within an intake air channel connected to an engine, so that the filter body is operable to adsorb a fuel vapor within the intake air channel when the engine has been stopped. Non-woven fabrics form the filter body. The non-woven fabrics have peripheral edge portions. Heat-pressing the peripheral edge portions of the non-woven fabrics forms the frame.
