US Patent 7370641 Monolith retainer

The invention relates to a monolith retainer for a fuel canister. The retainer has a head portion for retaining a monolith within a chamber of the fuel canister and a plurality of resiliently biased leg members, which extend from the head portion along a length of the monolith being retained. The legs are resiliently biased toward the inner wall of the chamber such that, when the monolith resides within the chamber, contact feet of the resiliently biased leg members abut against the monolith. A support ridge is also provided for preventing the monolith from traveling too far into the canister.
