ABSTRACT:
A fuel feed apparatus includes a lid member, a sub-tank, first and second supporting members, a biasing structure, a supporting portion, and a guide portion. The first and second supporting members are arranged in substantially radially end portions of the cylindrical portion to be substantially radially opposed to each other. The lid member is capable of axially moving relative to the sub-tank via the first and second supporting members. The biasing structure is arranged on the outer periphery of the first supporting member, and is received in the guide portion to bias the lid member and the sub-tank to be apart from each other. The first supporting member defines a groove portion that circumferentially divides an inner wall thereof into at least two planes. The first supporting member is capable of axially reciprocating through the supporting portion.
