1. A fuel tank comprising an internal component and a tank main body, wherein,
the internal component includes a columnar torso portion and two sets of a head portion, a neck portion and a shoulder portion, the neck portion connecting the shoulder portion and the head portion in each set thereof, the internal component being fixed on the tank main body via said two sets of the head portion, the neck portion and the shoulder portion, wherein
one set, of the two sets, of the head portion, the neck portion and the shoulder portion is formed at each end of the torso portion, and the shoulder portion is formed larger than the head portion and the neck portion, especially in a plan view and in a longitudinal direction of the head portion, an outer diameter of the head portion is larger than an outer diameter of the neck portion and smaller than an outer diameter of the shoulder portion,
one set, of the two sets, of the head portion and the neck portion is embedded in each of opposing internal surfaces of the tank main body, and
each of the head portions has a rotation-stopping shape, wherein
in thea plan view of the head portion, the rotation-stopping shape is formed with a difference in diameter between an outer diameter of the head portion in thea longitudinal direction and another outer diameter thereof in a direction orthogonal to the longitudinal direction,
the difference in diameter restricts rotation of the internal component relative to the tank main body along a circumferential direction of each of the head portions.
