PROBLEM TO BE SOLVED: To reduce costs and increase the capacity of a filter by shortening a path connecting a filter for preventing dusts and a canister, and a path connecting an atmosphere intake port and the canister. SOLUTION: This service hole cover 10 for accessing a fuel tank is constituted of a main service hole cover 12 and an undercover 14 fitted and integrated with it. An outside wall 14B, an inside wall 14C, and an atmosphere intake path 40 of a labyrinth structure are formed on the undercover 14, and an anti-dust filter 36 is held. Accordingly, as is similar to the conventional one, a path connecting the anti-dust filter and a canister and a path connecting the atmosphere intake port and the canister can be shortened. Also, a space 36 formed inside the inside wall 14C of the undercover 14 is effectively utilized, so as to also increase the capacity of the anti-dust filter. COPYRIGHT: (C)2005,JPO&NCIPI
