Resin-made fuel tank

A resin-made fuel tank comprising:

• a resin-made fuel tank body comprising split bodies;
• and a barrier sheet layer provided on an inner surface of the fuel tank body and provided for reducing permeation of fuel from the fuel tank body,
• wherein the split bodies comprise a first half body that is one split body and a second half body that is an other split body,
• wherein the barrier sheet layer comprises a first barrier sheet layer that is provided on the first half body and a second barrier sheet layer that is provided on the second half body,
• the first half body includes a first bonding surface of a first bonding portion that is formed at a peripheral portion of the first half body and the second half body includes a second bonding surface of a second bonding portion that is formed at a peripheral portion of the second half body, the first bonding surface is a surface facing the second half body and the second bonding surface is a surface facing the first half body, the first bonding surface and the second bonding surface are mated to each other,
• wherein an edge of the first barrier sheet layer is disposed in a vicinity of the first bonding surface, a first bent portion which bends toward an outside of the fuel tank body is provided at the edge of the first barrier sheet layer,
• wherein an edge of the second barrier sheet layer is disposed in a vicinity of the second bonding surface, a second bent portion which bends toward the outside of the fuel tank body is provided at the edge of the second barrier sheet layer,
• the first bent portion is positioned in the first half body at a position spaced apart from the first bonding surface,
• the second bent portion is positioned in the second half body at a position spaced apart from the second bonding surface, and the first bent portion and the second bent portion are spaced apart from each other,
• a protruding portion that is resin is formed at a bonding portion of the first bonding surface and the second bonding surface, and
• the first bent portion and the second bent portion are spaced apart from the protruding portion in an upward direction and in a downward direction, respectively.
