PROBLEM TO BE SOLVED: To provide a method for producing a resin fuel tank which does not require a complicated mechanism, and of which the wall thickness is inhibited from locally changing.SOLUTION: An elastic liner 56 is mounted to a tip of a rod 54 configured to move forward and backward with respect to a recess 46. First, the rod 54 is moved back from the recess 46, thereby bringing the elastic liner 56 into intimate contact with the recess 46. Size enlargement of a sheet body 100 including a molten resin in such a state allows the sheet body 100 to be arranged on the elastic liner 56 brought into intimate contact with the recess 46. In addition, air is supplied between the elastic liner 56 and the recess 46, thereby allowing expansion and deformation of the peripheral edge side of the elastic liner 56 to occur, bringing the sheet body 100 into intimate contact with the outer periphery portion of the undersurface of a mounting seat body 26, and sealing the outer periphery portion. Subsequently, the rod 54 is moved forward into the recess 46, thereby supplying the molten resin (sheet body 100) to an undercut shape portion 28 formed to protrude into the under surface of the mounting seat body 26 and forming a swaging portion 38.SELECTED DRAWING: Figure 7

    【課題】複雑な機構を要することなく、しかも燃料タンクの肉厚の局部的な変化を抑制した樹脂燃料タンクの製造方法を提供する。【解決手段】凹部46に対して進退自在に構成されたロッド54の先端に弾性体入子56が取り付けられている。先ず、ロッド54を凹部46から後退させることにより、弾性体入子56が凹部46に密着され、この状態で溶融樹脂からなるシート体100を賦形することにより、シート体100が凹部46に密着された弾性体入子56上に配置される。さらに、弾性体入子56と凹部46との間に空気を供給することによって、弾性体入子56の周端部側が膨張変形して取付座本体26の下面の外周部にシート体100を密着させ、シールする。続いて、ロッド54を凹部46内に前進させることによって、取付座本体26の下面に突出形成されたアンダーカット形状部28に溶融樹脂(シート体100)が供給され、カシメ部38が形成される。【選択図】図7
