Patent abstract
A housing 11 accommodates a pleated filter element 14. A fuel adsorbent member 16 is arranged in the housing 11 at a position downstream from the filter element 14. The fuel adsorbent member 16 adsorbs evaporative fuel leaking from an engine. The fuel adsorbent member 16 includes holding pleats 16g. Each of the holding pleats 16g is received in the space between an adjacent pair of the element pleats 14a of the filter element 14. This maintains the interval between the element pleats 14a. The holding pleats 16g are formed by folding the fuel adsorbent member 16.
