The tip of 22 is bent in a ring shape. As shown in FIGS. 2 and 3, a lid mounting shaft 17 is inserted into the ring shape and penetrates the mounting leg first holding piece 14 and the mounting leg second holding piece 15. Thus, the lid inner member 10 is rotatably attached to the arm member 20.

  An arm member locking piece 23 is formed from the end of the arm member main body 26 between the arm member first holding arm 21 and the arm member second holding arm 22. The arm member locking piece 23 is formed to be bent near the center. When the fuel filler lid 1 is opened, the side surface at the tip of the mounting leg clip holding portion 16 of the lid inner member 10 attached to the fuel filler lid 1 comes into contact with the arm member locking piece 23, so that the fuel filler lid 1 is It can be stopped at the opening angle.

Next, the locking clip 30 will be described with reference to FIGS. 6 and 7. In the present embodiment, the locking clip 30 is made of sheet metal, but can also be made of hard synthetic resin.
As shown in FIGS. 6 and 7, the locking clip 30 includes a clip body 31 and a clip holding leg 32 attached to the attachment leg clip holding portion 16 of the lid inner member 10 at one end of the clip body 31. Has been.

  The clip holding leg 32 is formed with a clip holding leg convex portion 34 having a tip portion curved. A clip holding push plate 33 is formed so as to face the clip holding leg 32 from the clip main body 31. Then, the clip holding leg 32 is inserted into the clip insertion hole 18 formed in the mounting leg portion 11 of the lid inner member 10. At that time, the clip holding leg convex portion 34 is fitted into the clip locking hole 19 formed on the base side of the clip insertion hole 18.

  Therefore, when the retaining clip 30 is attached to the attachment leg clip holding part 16 of the lid inner member 10, the clip holding leg 32 and the clip holding push plate 33 hold the attachment leg part clip holding part 16 therebetween, and the clip. The retaining clip 30 is not displaced by the holding leg convex portion 34 and the clip retaining hole 19, and the retaining clip 30 can be firmly attached.

  A clip locking piece 35 is formed at the other end of the clip body 31. The clip locking piece tip 36 at the tip of the clip locking piece 35 is formed so as to be slidably curved with respect to the tip of the arm member locking piece 23. The tip of the arm member locking piece 23 slightly protrudes from the trajectory through which the clip locking piece tip 36 passes.

  For this reason, when the fuel filler cap 1 is opened, the tip end portion of the arm member locking piece 23 passes over the tip end portion 36 of the clip member and is locked in the clip groove portion 38 to be described later. The clip groove 38 engages the piece 23. Further, even when the arm member locking piece 23 is detached from the clip groove portion 38, the clip locking piece distal end portion 36 bends and the clip locking piece distal end portion 36 gets over the distal end of the arm member locking piece 23 to be surely removed. be able to.

  When the locking clip 30 is attached to the mounting leg clip holding portion 16 of the lid inner member 10, the clip is clipped between the clip locking piece tip portion 36 and the tip of the mounting leg clip holding portion 16 of the lid inner member 10. A groove 38 is formed. When the fuel filler cap 1 is opened, the clip groove 38 engages the arm member locking piece 23 of the arm member 20. Therefore, when the fuel filler lid 1 is opened, the clip groove 38 can stop the rotation of the fuel filler lid 1 due to its own weight, and the fuel filler lid 1 is not closed during fueling, so that the lubrication workability can be improved.

  The locking clip 30 is formed with a clip spring portion 37 that comes into contact with the arm member 20 when the fuel filler cap 1 is closed. For this reason, when the lock of the lid lock hole 13 of the lid inner member 10 attached to the fuel filler lid 1 is released and the lock of the lid lock hole 13 is released, the elasticity of the clip spring portion 37 causes the oil filler lid 1 to be released. Can be slightly lifted from the vehicle body 3. Then, it becomes easy to pick the end of the fuel filler cap 1 by hand, and the fuel filler cap 1 can be opened further by hand.

Next, a method for opening and closing the fuel filler cap 1 will be described with reference to FIGS.
FIG. 8 shows a state where the fuel filler cap 1 is closed. First, the lock of the fuel filler cap 1 is released. That is, the lock pin inserted into the lid lock hole 13 of the lid lock piece 12 formed on the lid inner member 10 attached to the fuel filler lid 1 is removed from the lid lock hole 13 to release the lock.

  Then, as shown in FIG. 9, since the clip spring portion 37 of the locking clip 30 is in contact with the inner surface of the arm member 20, the mounting leg portion 11 is attached to the lid mounting shaft by the elastic force of the clip spring portion 37. The end of the fuel filler lid 1 on the side where the lid lock piece 12 is provided, that is, the end opposite to the lid mounting shaft 17 of the fuel filler lid 1 may slightly lift from the vehicle body 3. it can.

Therefore, it becomes easy to pick the end of the fuel filler cap 1 by hand, and the fuel filler cap 1 can be further opened by hand as shown in FIG.
When the fuel filler lid 1 is opened widely, the fuel filler lid 1 and the lid inner member 10 rotate together around the lid mounting shaft 17 of the lid inner member 10 attached to the back surface of the fuel filler lid 1.
FIGS. 11 and 12 are views of the arm member 20 and the mounting leg portion 11 of the lid inner member 10 in a state where the fuel filler cap 1 is completely opened. Further, FIG. 13 is an enlarged view of a circled portion in FIG.

  Then, as shown in FIGS. 12 and 13, the arm member locking piece 23 comes into contact with the clip locking piece tip 36 of the locking clip 30 attached to the lid inner member 10. When the fuel filler cap 1 is further rotated, as shown in FIG. 14, the tip end of the clip locking piece tip portion 36 slides on the tip end of the arm member locking piece 23. Furthermore, since the tip of the arm member locking piece 23 slightly protrudes from the trajectory through which the clip locking piece tip 36 passes, the tip of the arm member locking piece 23 deflects the clip locking piece tip 36. As shown in FIG. 15 (bends downward in FIG. 14), the clip groove 38 is engaged. The clip groove portion 38 is a groove formed between the distal end portion of the clip locking piece 36 and the attachment leg portion clip holding portion 16.

  Since the locking clip 30 is formed of sheet metal, the clip locking piece tip 36 is elastically bent, and the arm member locking piece 23 can be reliably locked by the clip groove 38. Further, even when the arm member locking piece 23 is detached from the clip groove portion 38, the tip of the arm member locking piece 23 can be bent over the clip locking piece tip portion 36 and can be reliably removed.

  FIG. 16 shows a change in the rotation torque of the fuel filler cap 1 at this time. Line X in FIG. 16 is a change in rotation torque when the fuel filler cap 1 is closed by its own weight, and line Y is a change in rotation torque of the fuel filler cap 1 of the present invention. 16 indicates the torque when the arm member locking piece 23 of the arm member 20 gets over the clip locking piece tip 36 and is locked to the clip groove 38 when the fuel filler cap 1 is opened. Shows changes. Thus, the torque of the portion indicated by Z is larger than the torque of rotation when the fuel filler cap 1 is closed by its own weight, and the fuel filler cap 1 can be prevented from closing by its own weight.

  In this way, when the fuel filler cap 1 is opened, the arm member locking piece 23 is locked in the clip groove 38 between the mounting leg clip holding portion 16 of the lid inner member 10 and the clip locking piece tip 36, The fuel filler cap 1 is held with a predetermined torque. For this reason, when the oil filler lid 1 is opened, the clip groove portion 38 can stop the oil filler lid 1 from rotating due to its own weight, and the oil filler lid 1 is not closed during refueling, so that the lubrication workability can be improved. .

  When the fuel filler cap 1 is opened, when the arm member locking piece 23 of the arm member 20 is locked to the clip groove 38, the side surface of the mounting leg clip holding portion 16 is the side surface of the tip of the arm member locking piece 23. Abut. For this reason, it is possible to prevent the fuel filler lid 1 from being opened excessively further and to prevent the fuel filler lid 1 from contacting the vehicle body or the like.

  Further, when the fuel filler cap 1 is closed, the locking clip 30 is formed of a sheet metal and has elasticity.
