Next, a procedure for supplying fuel will be briefly described.
In the vehicle 12 shown in FIG. 2, when fuel is supplied, the lock is released when the driver's door lock (not shown) is opened after the vehicle stops at the gas station. The fuel lid 15 has not opened yet. Subsequently, when the fuel lid 15 is pushed by hand, it is pushed by the push lifter 33, and the fuel lid 15 automatically opens and comes out, so that it is further opened by hand (see FIG. 1). When closing the fuel lid 15, the opened fuel lid 15 is closed against the push lifter 33. Next, when the door lock of the driver's seat is closed, the lock pin 31 is fitted into the striker portion 26 and the fuel lid 15 is locked.

Next, the operation of the fuel filler cap structure for a vehicle according to the present invention will be described.
In the fuel filler cap structure 11 shown in FIG. 1, when the urging means 27 is locked to the engagement protrusion 63 disposed on the vehicle body 13 side together with the striker portion 26 disposed on the fuel lid 15 that is opened and closed, the urging means 27 is Since the urging force is applied to the engaging protrusion 63, the fuel lid 15 is not opened, and the closed state can be maintained. As a result, it is not necessary to use a member for obtaining an urging force on the hinge 22 that supports the fuel lid 15 so as to be freely opened and closed, for example, an S-shaped spring, and it is not necessary to form a space for arranging the S-shaped spring. . Therefore, the fuel adapter 16 can be reduced in size and the production cost can be reduced.

  Further, when the urging means 27 is locked to the engaging protrusion 63 disposed on the vehicle body 13 side together with the striker portion 26 disposed on the fuel lid 15 to be opened and closed, the urging means 27 applies an urging force to the engaging protrusion 63. Therefore, when the door lock is unlocked, the fuel lid 15 can be urged in the closing direction by the urging force of the urging means 27, and the opening of the fuel lid 15 unintended by the occupant can be suppressed.

FIG. 7 is a view for explaining a mechanism for closing the fuel lid of the fuel filler cap structure of the present invention. 1 to 6 will be used together for explanation.
In the fuel filler cap structure 11 shown in FIG. 1, when the fuel lid 15 is closed, the urging means 27 comes into contact with the engagement protrusion 63 on the vehicle body 13 side as shown by a solid line. When the fuel lid 15 is further closed, the extending portion 75 and the sandwiching portion 76 of the biasing means 27 are elastically deformed and start to open as indicated by the arrow b1. When the clamping portion 76 passes through the engagement protrusion 63, the pressing is performed so as to be sandwiched by the elastic force (biasing force) (in the direction of the arrow b2), so that the fuel lid is caused by the component force of the elastic force and the force that is continuously pressed by the hand. No. 15 continues to rotate in the closing direction (the direction of arrow a2). On the other hand, when the pushed push lifter 33 reaches the retracted state (see FIG. 4), the compression coil spring 53 of the push lifter 33 does not extend, so even if the hand is released from the fuel lid 15 at the fuel lid closed position E, the fuel lid 15 Is closed.

  When the fuel lid 15 is closed (fuel lid closed position E), the biasing means 27 applies a biasing force to the engaging protrusion 63 by the holding portion 76 and the extending portion 75, so that the fuel lid 15 is closed. Then, the biasing means 27 does not automatically close the fuel lid 15. Therefore, it is possible to prevent an object from being caught between the fuel lid 15 and the fuel adapter 16.

Further, the urging means 27 closes the fuel lid 15 by the urging force applied to the engaging protrusion 63 by the clamping portion 76 and the extending portion 75 when the fuel lid 15 is closed (fuel lid closed position E). Pulling in the direction, the back of the fuel lid 15 is pressed against the push lifter 33. As a result, even if a lateral G (in the direction of arrow b3) occurs when the vehicle 12 is bent to the right when the lock of the fuel lid 15 is released due to the unlocking of the door lock, the fuel lid 15 Will not open.
Further, even when water is sprayed on the fuel lid 15 at the time of car washing at the time of unlocking, the fuel lid 15 does not open.

  The urging means 27 is applied to the push lifter 33 by the urging force applied to the engaging protrusion 63 by the clamping portion 76 and the extending portion 75 when the fuel lid 15 is closed (fuel lid closed position E). The back is pressed. As a result, fine movement in the opening / closing direction of the fuel lid 15 can be prevented, and vibration (rattle) of the fuel lid 15 can be prevented.

  Since the urging force is set to be smaller than the opening force of the push lifter 33, the urging means 27 is clamped from the engaging protrusion 63 against the urging force by the opening force when the push lifter 33 extends to the protruding state. The part 76 can be opened and pulled out as shown by the arrow b1, and the fuel lid 15 can be automatically opened.

  In the fuel adapter 16, it is not necessary to form a concave storage portion for storing a hinge or a spring in the first wall portion 41 at one end of the side wall portion 35. Therefore, the fuel adapter 16 can be reduced in size and the production cost can be reduced.

  Since the urging means 27 mainly includes a fixing portion 74, an extending portion 75, and a clamping portion 76, the structure of the urging means 27 is simplified.

  In the fuel lid locking mechanism 23, when the opening of the clamping part 76 becomes large, the extension part 75 comes into contact with the opening stopper part 68, so that the urging force can be maintained.

  In the fuel lid locking mechanism 23, the urging attachment portion 57 is formed on the striker portion 26, and the first claw portion 81 and the second claw portion 82 are formed on the urging means 27. The urging means 27 can be fixed before fastening only by hooking the 1 claw portion 81 and the second claw portion 82, and the urging means 27 is easily assembled.

  Further, when the biasing means 27 is attached to the striker portion 26, the opening stopper portion 68 is prevented from rotating. Therefore, even if a force in the rotation direction by screwing using the male screw member 71 is applied, the biasing means 27 The rotation can be prevented, and the urging means 27 can be easily assembled to the striker portion 26.

  Note that the fuel refueling port lid structure for a vehicle according to the present invention is employed in the fuel lid that covers the fuel refueling port in the embodiment, but can also be employed in a lid or cover that closes an opening other than the fuel refueling port so that it can be opened and closed.
