Structure for connecting tubular member to fuel tank

A structure for connecting a tubular member to a fuel tank, comprising:

• a fuel tank made of resin;
• a tubular member made of resin and provided with a press fit portion on a side of one axial end thereof so as to be fixedly connected to an opening formed on the fuel tank;
• a cylindrical convex portion formed integrally with the fuel tank to define the opening;
• and
• at least one continuous annular projection integrally formed with the tubular member on the outer peripheral surface of the press-fit portion, a face of the annular projection in direction axially of one end of the tubular member being formed as to extend outwardly and inclinedly with respect to the axial direction of the tubular member from one end toward the other end thereof;
• the press-fit portion being press-fitted into the cylindrical convex portion such that the annular projection bites into an inner peripheral surface of the cylindrical convex portion in a manner providing continuous circumferential contact between the annular projection and the inner peripheral surface of the cylindrical convex portion.
