FUEL SUPPLY DEVICE FOR ENGINE

WIPO Patent Application WO/2012/144483

A1

A fuel supply device for an engine, wherein a base member (15) which comprises, as one body, a base part (15a) that extends vertically on the side of a throttle body (5), and a housing cylinder part (15b) that has, on one end side, an end wall (15c) continuous with the lower section of the base part (15a) and is formed in a bottomed cylinder shape is integrally coupled to a body (7), a pump housing case (14) that forms a fuel storage chamber (26) is configured from the housing cylinder part (15b) and a bottomed cylinder-shaped housing cover joined to the housing cylinder part (15b) via a seal member and is disposed below the body (7), and a vapor discharge path (48) for discharging vapor generated in the fuel storage chamber (26) is formed in the base part (15a) so as to lead to the upper section in the fuel storage chamber (26) and extend vertically. Consequently, the device is made more compact, and vapor can be more easily discharged from the fuel storage chamber while the assembling performance of each component is improved, and strength and toughness against a load generated by vibration or the like are improved.
