1. A fuel cap device for closing an inlet of a rearwardly located automobile fuel tank, comprising:

  • a substantially cylindrical closer for closing said inlet, and an operating portion formed on an upper part of said closer, wherein;

    said operating portion comprises a projection passing through a center of the upper part of said closer and bridging in a radial direction;

    said operation portion being rotatable to thereby engage said projection with said closer, and said closer with said inlet when said closer is inserted into said inlet;

    said operating portion being positioned when said operating portion is rotated until said closer is in a fully engaged state with said inlet such that said operating portion transmits to said closer a torque in an engaging direction of rotation when an external rear impact force acts on said operating portion;

    a longitudinal orientation of said operating portion is at an angle more than 90° and

    180°

    when the closer is in the fully engaged state with said inlet; and

    a relative orientation of said operating portion and said closer in a non-torqued state after said closer closes said inlet remains a predetermined angle.
