Abstract
A tubular resin contains small animal repelling chemical. And canister structure installed in an automobile comprises the above tubular resin on the inner wall of an air inlet port portion of a drain pipe. The canister structure absorbs evaporated fuel from a fuel tank by a absorbent in a main body of a canister and then supplies desorbed fuel from the adsorbent together with the air sucked from the drain pipe to an engine side. The tubular resin prevents entering of a small animal into the drain pipe and also building of its nest.
