VAPORIZED FUEL TREATMENT APPARATUS

PROBLEM TO BE SOLVED: To prevent or reduce breakage of the shoulder portion of an adsorbent by a holding member for elastically holding the adsorbent in a case.SOLUTION: The vaporized fuel treatment apparatus includes an adsorbent 34 of a honeycomb structure capable of adsorbing/desorbing vapor contained in vaporized fuel gas, the sub-case body 16 of a case for housing the adsorbent 34, and holding members 65 and 66 for elastically holding the adsorbent 34 in the sub-case body 16. The holding members 65 and 66 independently include outer peripheral surface-holding materials 71 and 77 brought into contact with the outer peripheral surface of the adsorbent 34, and the end surface-holding materials 72 and 78 brought into contact with the end surface of the adsorbent 34 and having elasticity lower than that of the outer peripheral surface-holding materials 71 and 77.
