Further, the second link member 17 is closed by the urging force F by the spring 43 with the movement of the support portion center.

  Here, if the second link member 17 is not provided, the first link member 15 rotates around both the support pin 27 on the support bracket 19 side and the support pin 27 on the mounting bracket 9 side. Therefore, the fuel lid 13 may interfere with the vehicle body 1 at the time of opening and closing. However, according to the present embodiment, the opening and closing operation of the fuel lid 13 by the first link member 15 is supported by the second link member 17. Can be smoothly opened and closed.

  Below, the effect by embodiment of this invention is demonstrated.

  The link member supports a first link member 15 having one end pivotally supported by the fuel filler port side 5 and the other end pivotally supported by the fuel lid 13, and the rotation of the first link member 15. And a second link member 17 that restricts the opening / closing locus of the fuel lid 13 to a predetermined path. For this reason, compared with the case where the fuel lid 13 is connected to the vehicle body side only through the first link member 15, the fuel lid 13 opens and closes smoothly. There is no interference. Regardless of the shape (modeling) of the fuel lid 13, the fuel lid 13 having various shapes can be efficiently opened and closed. Moreover, according to this embodiment, it is not necessary to provide guide parts, such as a receiving member provided in the conventional fuel lid, and the fuel lid 13 can be configured with a simple structure.

  When the opening / closing angle of the fuel lid 13 is less than a predetermined value, the second link member 17 biases the fuel lid 13 in the closing direction, and when the opening / closing angle of the fuel lid 13 is more than a predetermined value, the fuel lid 13 is An urging means (spring 43) for urging in the opening direction is provided. Therefore, the fuel lid 13 can be reliably held in the closed state. On the other hand, when the fuel lid 13 is opened, the fuel lid 13 is automatically opened by the biasing means when the opening / closing angle exceeds a predetermined value. Become very smooth.

  Since the urging means is the spring 43 attached to the second link member 17, the above effect can be obtained with a simple structure and at a low cost.

  Since the second link member 17 is configured to contact the first link member 15 when the fuel lid 13 is fully opened, the fully open state of the fuel lid 13 can be reliably maintained.

  Since the end portion (flange portion 21) of the fuel lid 13 is configured to come into contact with the first link member 15 when the fuel lid 13 is fully opened, the end portion of the fuel lid 13 acts as a stopper, and the fuel lid 13 The fully opened state can be more reliably maintained.

  In addition, since both the first link member 15 and the second link member 17 are disposed in the fuel filler opening portion 5, the appearance on the appearance is improved. Further, the opening / closing angle at which the urging force of the spring 43 is reversed can be adjusted as appropriate by changing the geometry of the first and second link members 15 and 17.
