Patent ID: 7608137

Claim:
An air cleaner having a filter element that filters air, comprising: a housing that accommodates the filter element; a fuel adsorbent member that is secured to the housing and adsorbs evaporative fuel, the fuel adsorbent member being provided downstream from the filter element, the fuel adsorbent member having a sheet-like shape as a whole; and a holder that holds the fuel adsorbent member in a state secured to the housing when the fuel adsorbent member receives a backfire pressure from an intake system of an engine, the holder being arranged in a portion of the fuel adsorbent member in which an extent of influence by the backfire pressure is great, wherein the holder reduces the backfire pressure in the portion of the fuel adsorbent member in which the extent of influence by the backfire pressure is great, wherein the holder is defined by a release portion that releases the backfire pressure to an upstream side of the fuel adsorbent member, wherein the release portion is arranged in a portion of the fuel adsorbent member, wherein the release portion is defined by a plurality of holes passing through the fuel adsorbent member, the holes being spaced from one another and having a through-hole structure that connects between upstream and downstream sides of the fuel adsorbent member.
