FUEL FEEDING DEVICE

PROBLEM TO BE SOLVED: To attain suppression of filter clogging in a fuel feeding device attaining introduction of external air through an air filter. SOLUTION: In the fuel feeding device 10, a body part 108 continued to a cap attachment part 106 of a retainer 100 is diameter-enlarged, a filler neck 150 is attached to the body part 108, and the cap attachment part 106 and the body part 108 are surrounded by a cover. Further, an air flow passage from an air introduction part 178 of a cover upper end edge to a filter storage area 210 in a filter storage vessel 200 of the cover lower end is made to a flow passage in which an upstream side air flow passage 190 around an outer periphery of the cap attachment part 106, a connection air passage 191 around an outer periphery of the body part 108 including a connection step part 110 and a downstream side air flow passage 192 around an outer periphery of a lower end of the body part 108 are connected to communicate with each other by rib notches 194k, 195k. The flow passage is made to a labyrinthine flow passage in which a flow of air is bent. COPYRIGHT: (C)2009,JPO&INPIT
