FUEL SUPPLY

In a fuel supply apparatus (33), a lid (40) includes a first guide tube (48) provided extending toward inside of a fuel tank (31); a reservoir (34) is provided extending from a bottom thereof toward the side of the lid (40) and houses the fuel pump (35) as well as includes a second guide tube (41) that inscribed in the first guide tube (48) and fitted thereto in a slidable manner; and an elastic member (49) is provided that is inserted and fitted to an outer circumference of the foregoing second guide tube (41) as well as interposed between the reservoir (34) and the lid (40) to enable the reservoir (34) to travel telescopically with respect to the lid (40). As a result, it becomes possible to obtain a fuel supply apparatus capable of stably adapting to dimensional change in tank without applying any excessively large load to the fuel tank.
