The present invention relates to a plastic fuel tank for a vehicle, wherein a honeycomb-shaped fusion protrusion (330) is formed on a baffle fusion surface (321) in a structure in which a plastic baffle (2) is heat-fused to be coupled. Accordingly, a tank fusion unit (110) is heat-fused and coupled to come in contact with the surface of the baffle fusion surface (321) while covering the honeycomb-shaped fusion protrusion (330). Moreover, a resin filling groove (340) is formed on the edge of the baffle fusion unit (320), and thus a side surface unit (121) of a protrusion unit (120) is coupled to cover the edge of the baffle fusion unit (320) while the side surface unit is filled with the resin filling groove (340).
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)이 형성됨에 따라 돌기부(120)의 측면부(121)가 수지채움홈(340)으로 채워지면서 배플융착부(320)의 테두리를 감싸도록 결합되는 것이다.
