The present invention relates to a plastic fuel tank for a vehicle. In a structure in which a plastic baffle (2) is bonded by thermal fusion, a honeycomb-shaped fusion protrusion (330) is formed on the baffle fusion surface (321). Accordingly, a tank fusion unit (110) covers the honeycomb-shaped fusion protrusion (330) and is thermally fused to form surface contact with the baffle fusion surface (321). In addition, a resin filling groove (340) is formed on an edge of a baffle fusion unit (320). Accordingly, the side surface (121) of a protrusion unit (120) is filled with the resin filling groove (340) and coupled to surround a rim of the baffle fusion unit (320). An objective of the present invention is to eliminate a quality problem of the plastic fuel tank caused by defective fusion of the plastic baffle.

    본 발명은 차량용 플라스틱 연료탱크에 관한 것으로, 플라스틱 배플(2)이 열융착으로 결합되는 구조에서 배플융착면(321)에 벌집모양의 융착돌기(330)가 형성됨에 따라 탱크융착부(110)가 벌집모양의 융착돌기(330)를 커버링하면서 배플융착면(321)과 면접촉을 이루도록 열융착 결합되고, 배플융착부(320)의 테두리에 수지채움홈(340)이형성됨에 따라 돌기부(120)의 측면부(121)가 수지채움홈(340)으로 채워지면서 배플융착부(320)의 테두리를 감싸도록 결합되는 것이다.
