<p>PROBLEM TO BE SOLVED: To promote the detachment of fuel components even in a case of low purge air amount, and to improve purge efficiency.SOLUTION: In a sub canister 20, a first port 22 is connected to a drain port 16 of a main canister 10 through a tube 19. A casing 29 of the sub canister 20 is composed of a body 27 and a cover 28, and a honeycomb activated carbon 40 is stored in an adsorption material storage chamber 30 formed on the body 27 with a packing 42 and a shock absorber 44. Between the body 27 and the cover 28, a glass plate 46 is disposed separately from an end surface of the activated carbon 40. In a space of the cover 28, a lamp heater 60 for heating the activated carbon 40 is disposed. The lamp heater 60 is composed of a tube 62 including a light source, and a connector 64 connected to one end of the tube 62, and arranged so as to make an axis in a longitudinal direction parallel with the glass plate 46 and the end surface of the activated carbon 40.</p> |
