It is provided below the line.
JP 2004-106584 A

  However, in the example described in Patent Document 1, the open rod arranged on the lock means side is provided below the line connecting the lock means and the hinge portion, and the open rod and the lock means are offset. It is in. For this reason, when trying to open the fuel lid by the pushing action of the open rod, even if the open rod pushes the fuel lid, until the locking means is released, the bending moment (about the line connecting the locking means and the hinge part ( (Twisting) is applied to the entire fuel lid, and thus to the locking means and the hinge portion. Therefore, when trying to open the fuel lid by the pushing action of the open rod, it is improved in order to release the locking means smoothly and ensure the sliding performance of the hinge part so that the lid can be opened smoothly. There is room for.

  This invention is made | formed in view of the said situation, The objective is to provide the lid structure which can open | release a lid smoothly.

  In order to solve the above-mentioned problem, a lid structure according to claim 1 is disposed in a lid that is pivotally attached to a vehicle body via a hinge means, and a portion of the lid that is spaced apart from the hinge means, Locking means for holding the lid closed to the vehicle body, and the lid is disposed coaxially with the locking means and protrudes from the vehicle body side to the lid side so that the lid is separated from the hinge means. And a push pin for applying a biasing force in the opening direction.

  In the first aspect of the invention, the fact that the push pin is arranged coaxially with the locking means means that an axis extending along the moving direction of the push pin and an axis extending along the locking direction of the locking means. In addition to including the case where they completely coincide with each other, it includes the case where the axis extending along the moving direction of the push pin and the axis extending along the locking direction of the locking means are slightly shifted (so-called substantially coaxial).

  In the lid structure according to the first aspect, the lid is held in a state of being closed to the vehicle body by the lock means disposed in a portion separated from the hinge means. When the push pin is protruded from the vehicle body side to the lid side from this holding state, an urging force in the opening direction by the push pin is applied to a portion separated from the hinge means of the lid, and the lid rotates in the opening direction. Here, in the lid structure according to the first aspect, the push pin is arranged coaxially with the locking means. Therefore, since the offset between the lock means and the push pin is reduced as compared with the conventional case, even when the push pin applies a biasing force to the lid in the opening direction, the entire lid, and consequently the lock means and the hinge means. The bending moment (torsion) around the line connecting the locking means and the hinge means acting is suppressed. As a result, the locking means can be released smoothly and the sliding performance of the hinge means can be ensured (that is, the locking means can be released smoothly and the sliding of the hinge means is not hindered), and the lid can be smoothly moved. It can be opened.

  According to a second aspect of the present invention, in the lid structure according to the first aspect, the lock means is a lock portion provided in the vehicle body through which the push pin passes, and a lock portion provided in the lid for locking with the lock portion. And a locked part.

  In the lid structure according to the second aspect of the present invention, the lock means is constituted by the lock portion provided on the vehicle body and the locked portion provided on the lid, and the lid is held in a closed state on the vehicle body. At this time, in the lid structure according to claim 2, as an example of a configuration in which the push pin is arranged coaxially with the lock means, the push pin passes through a lock portion provided on the vehicle body of the lock means. . According to this configuration, since the push pin passes through the lock portion, the push pin and the lock portion can be downsized in the axial direction and the radial direction, so that it is possible to reduce restrictions on the arrangement of the lid.

  According to a third aspect of the present invention, in the lid structure according to the first or second aspect, the lock means includes a lock portion provided in the vehicle body through which the push pin passes, and a lock portion provided in the lid. And a locked portion that locks, and the push pin applies an urging force in the opening direction of the lid to a central portion of the locked portion, so that the locking portion and the locked portion are It is characterized by releasing the lock.

  In the lid structure according to the third aspect of the present invention, the locking means is constituted by the lock portion provided on the vehicle body and the locked portion provided on the lid, and the lid is held in a state of being closed to the vehicle body. And a rod penetrates the lock part provided in the vehicle body among the lock means, and gives the urging | biasing force to the opening direction of a lid with respect to a to-be-locked part. Thereby, the locked state of the lock part and the locked part is released, and the lid rotates in the opening direction. At this time, in the lid structure according to claim 3, the push pin applies a biasing force in the opening direction of the lid to the center portion of the locked portion to release the lock between the locked portion and the locked portion. . Accordingly, the offset between the lock means and the push pin becomes zero, and the bias of the bending moment (torsion) about the lid connecting the lock means and the hinge means acting on the entire lid and eventually the lock means and the hinge means is eliminated. . As a result, the locking means can be released more smoothly and the slidability of the hinge means can be ensured (that is, the locking means can be released more smoothly and the sliding of the hinge means is further inhibited). The lid can be opened more smoothly.

  According to a fourth aspect of the present invention, in the lid structure according to the second or third aspect, the lock portion is configured to have a locking portion on an outer peripheral portion, and the locked portion is formed on the lid. A main body portion to be fixed, and extends radially outward from a central portion of the main body portion, and engages with the locking portion from a radially outer side of the lock portion to a portion on the extended end portion side. A clip arm configured to have a locked portion to be stopped, and the push pin bends the clip arm by pushing a proximal end portion of the clip arm toward the lid side. The locking state between the locking portion and the locked portion is released, and a biasing force in the opening direction of the lid is applied to the proximal end portion of the clip arm.

  In the lid structure according to claim 4, when the locked portion of the clip arm formed on the locked portion is locked to the locked portion of the locked portion, the locked portion and the locked portion are opposed to each other. The part and the locked part are locked, and the lid is held in the closed state on the vehicle body. When the push pin is protruded from the vehicle body side to the lid side from this holding state, the base end side portion of the clip arm is pushed to the lid side by the push pin, and the clip arm is bent. When the clip arm is bent in this manner, the locked state between the locking portion and the locked portion is released, and the push pin pushes the proximal end portion of the clip arm toward the lid side. Thus, the biasing force in the opening direction is applied, and the lid rotates in the opening direction. Thus, according to the lid structure of the fourth aspect, the locking means can be released smoothly and the lid can be smoothly rotated in the opening direction without hindering the sliding of the hinge means. Can do.

  According to a fifth aspect of the present invention, in the lid structure according to any one of the first to fourth aspects, the push pin is separated from the lid when not operating.

  The lid structure according to claim 5, wherein the push pin is separated from the lid when not operating, that is, when no urging force is acting on the lid toward the vehicle body. Therefore, for example, even when the operator applies a biasing force to the vehicle body side with respect to the lid to close the lid, the push pin does not apply a biasing force to the lid in the opening direction of the lid. No extra closing force is required when closing the lid. Further, in the case where the locking means is configured as described in claim 4, even if a biasing force further acts on the lid in a closed state on the vehicle body, the clip arm provided on the push pin and the lid The state of being separated from the base end side portion is maintained. Therefore, it is possible to prevent the locking state between the locking portion and the locked portion from being released due to the clip arm bending due to the pressing pin being pressed.

  According to a sixth aspect of the present invention, in the lid structure according to any one of the first to fifth aspects, the push pin is disposed so as to overlap with a support range of the lid by the hinge means. It is characterized by being.

  In this case, the support range by the hinge means of the lid corresponds to the support range by this one hinge part when the hinge means is configured to have one hinge part. In the case where a plurality of hinge parts are provided, the range is not limited to the support range by the plurality of hinge parts. The range between the pair of hinge portions is also included in the support range).

  By the way, when the push pin is disposed at a position outside the support range of the lid hinge means, when the push pin applies a biasing force to the lid in the opening direction of the lid, the hinge means against the hinge means. A bending moment (torsional force) is applied to bend the rotation axis. The bending moment for bending the pivot shaft of the hinge means increases as the position of the push pin moves away from the support range in the direction of the pivot axis of the hinge means. Therefore, as in the lid structure according to claim 6, if the push pin is disposed so as to overlap with the support range of the lid hinge means, the push pin biases the lid in the opening direction of the lid. The bending moment for bending the rotation shaft of the hinge means can be reduced or eliminated. Thereby, the slidability of the hinge means is further improved, and the lid can be opened more smoothly.

  As described in detail above, according to the present invention, it is possible to smoothly release the locking means and to ensure the slidability of the hinge portion, so that the lid can be smoothly opened.

It is configured to rotate between a position open to the outside of the vehicle indicated by a chain line). The hinge portion 24 is provided with an urging member (not shown) that constantly urges the fuel lid 20 in the opening direction (arrow P1 direction). The fuel lid 20 is provided when a lock mechanism 54 described later is released. The urging force of the urging member is rotated in the opening direction.

  Further, as shown in FIG. 3, the fuel lid structure 10 of the present embodiment is provided with a lock device 26 and an opening device 28. The lock device 26 holds the fuel lid 20 in the closed state to the vehicle body so as to close the fuel supply space portion 14, and the opening device 28 rotates the fuel lid 20 to the outside of the vehicle body (in the direction of arrow P <b> 1) to move the fuel supply space portion 14. It is the structure exposed to the outside.

  The lock device 26 is provided with a lock base 30 at an inner portion in the vehicle width direction of the body panel 12 in which the oil supply space 14 is recessed. The lock base 30 is in close contact with the vehicle inner side surface of the body panel 12 and extends in the vehicle front-rear direction, and extends inward in the vehicle width direction from both ends of the fixed wall portion 32 in the vehicle front-rear direction. The side walls 34 and 36 are formed. The fixed wall portion 32 is provided with a male screw portion 42 that protrudes outward in the vehicle width direction. On the outer peripheral surface of the male screw portion 42, a screw thread 42A is formed. Further, a through hole 44 through which a push pin 64 of an opening device 28 described later is inserted is formed through the male screw portion 42 along the axial direction (vehicle width direction).

  The lock base 30 is fixed to the body panel 12 in the following manner. That is, the male screw portion 42 is inserted into the through-hole 46 formed in the body panel 12 from the inside in the vehicle width direction, and the axially screwed portion is projected from the through-hole 46 of the male screw portion 42 to the outside in the vehicle width direction. A nut (a deformed nut) 48 having a hole 48A formed therethrough is screwed from the outside in the vehicle width direction. Thereby, the lock base 30 is fixed to the body panel 12.

  The portion of the nut 48 that fixes the lock base 30 to the body panel 12 on the fuel lid 20 side has a groove-like locking portion 52 as a locking portion for locking a claw portion 62 provided on a clip arm 60 described later. Are formed along the outer circumferential direction. On the other hand, a clip 56 constituting a lock mechanism 54 as a lock means in combination with the nut 48 is provided at a portion facing the nut 48 of the fuel lid 20. That is, in this embodiment, the nut 48 constitutes a mail member as a lock portion of the lock mechanism 54, and the clip 56 constitutes a mail member as a locked portion of the lock mechanism 54.

  The clip 56 provided in the lock mechanism 54 is configured to have a disk-shaped clip main body 58 on the fuel lid 20 side. The entire clip 56 is integrally fixed to the fuel lid 20 by fixing the clip main body portion 58 to the fixing portion 22 formed on the inner surface of the fuel lid 20 in the vehicle width direction. The clip main body 58 is formed with a plurality of clip arms 60 that extend radially outward from the central portion of the clip main body 58. As will be described later, each clip arm 60 is pressed against the clip main body 58 when a proximal end portion (in this example, this portion is a central portion of the clip 56) is pushed by a push pin 64. It is configured to be elastically deformable so as to fall (see FIG. 4B). Further, a claw portion 62 as a locked portion that is locked to the groove-shaped locking portion 52 from the radially outer side of the nut 48 is formed at the extending end portion of each clip arm 60.

  The claw portion 62 protrudes from the extending end portion of the clip arm 60 toward the inside in the radial direction of the lock mechanism 54. Further, the wall surface located on the outer side in the vehicle width direction of the claw portion 62 is formed along the vehicle front-rear direction and is locked to the wall surface located on the outer side in the vehicle width direction of the groove-like locking portion 52. . Moreover, the wall surface located in the vehicle width direction inner side of the nail | claw part 62 is formed in the taper shape, and becomes a structure which deform | transforms so that the clip arm 60 may be expanded when the fuel lid 20 is closed by this. In the present embodiment, the plurality of clip arms 60 are, for example, arranged at substantially equal intervals along the circumferential direction of the clip body 58 so as to surround the push pin 64 and can be chucked to the nut 48 at three points. It is made into the composition.

  On the other hand, the opening device 28 is provided with a push pin 64 (push rod) for rotating the fuel lid 20 in the opening direction (arrow P1 direction). The push pin 64 is disposed coaxially with the nut 48 (and thus the lock mechanism 54) by being inserted into the through hole 44 of the male screw portion 42. In the present embodiment, the push pin 64 and the lock mechanism 54 including the nut 48 and the clip 56 are separated from the hinge portion 24 of the fuel lid 20 (as shown in FIG. 2). The rear portion of the vehicle) and on a virtual line L2 that is orthogonal to the rotation axis L1 of the hinge portion 24 and passes through the central portion of the hinge portion 24 in a side view of the vehicle.

  Further, as shown in FIG. 3, a flange-like stopper 66 extending along a direction orthogonal to the longitudinal direction of the push pin 64 is provided at the intermediate portion in the longitudinal direction of the push pin 64. As will be described later, the stopper 66 contacts the peripheral edge of the through hole 44 of the fixed wall portion 32 when the push pin 64 moves outward in the vehicle width direction as the bell crank 68 rotates. Is restricted from moving outward in the vehicle width direction. That is, in this embodiment, the push pin 64 can urge the fuel lid 20 in the opening direction by the stroke S from the stopper 66 to the fixed wall portion 32.

  Further, the opening device 28 is provided with a bell crank 68 and a lid cable 70 for moving the push pin 64 forward and backward along the vehicle width direction. The bell crank 68 is formed in a generally square shape bent at a substantially right angle. The bent portion of the bell crank 68 is rotated by a pin 72 on a support portion 38 formed on the side wall portion 34 of the lock base 30. It is fixed freely. Then, the free end side portion of one crank portion 74 of the bell crank 68 is rotatably connected to the rear end side (vehicle width direction inner side) portion of the push pin 64. At this time, in order to smoothly convert the rotational movement of the bell crank 68 into the linear movement of the push pin 64, a long hole extending in a direction orthogonal to the longitudinal direction of the push pin 64 is formed in the rear end portion of the push pin 64. 76 is formed, and a pin 78 provided at a portion on the free end side of the crank portion 74 is movably inserted into the long hole 76. Further, the bell crank 68 is always urged so as to rotate in the arrow Q1 direction of FIG. 3 so as to pull back the push pin 64 inward in the vehicle width direction by an urging member (not shown) provided on the side wall 34 of the lock base 30. Has been.

  A lid cable 70 is connected to the free end portion of the other crank portion 80 of the bell crank 68. The lid cable 70 is connected to a fuel lid opener 84 disposed in the vicinity of the driver's seat through a through hole 40 formed in the side wall portion 36 of the lock base 30 and a grommet 82 provided in the through hole 40. . The fuel lid opener 84 is configured, for example, as a lever. By pulling the lever in a predetermined direction, the lid cable 70 is pulled in the arrow R direction, and thereby the bell crank 68 is rotated in the arrow Q2 direction. It is the composition which makes it.

  Further, in a normal state where the fuel lid opener 84 is not pulled, the bell crank 68 is restricted from rotating in the direction of the arrow Q1 by a position restricting means (not shown) provided on the fuel lid opener 84 side, the side wall portion 34, or the like. Thus, it is configured to stop at the initial position shown in FIG. That is, when the fuel lid opener 84 is not pulled, the bell crank 68 is maintained in a stopped state at a predetermined rotation angle as shown in FIG. At this time, the push pin 64 is pulled inward in the vehicle width direction by the bell crank 68, and the front end portion of the push pin 64 located on the outer side in the vehicle width direction slightly protrudes from the nut 48 outward in the vehicle width direction. A predetermined clearance C is secured and separated from the proximal end portion of the clip arm 60.

  Next, the operation of the fuel lid structure 10 having the above configuration will be described with reference to FIGS. 1 to 5.

  FIG. 4 shows a state in which the fuel lid 20 is opened in the fuel lid structure 10 according to the embodiment of the present invention. More specifically, FIG. 4A shows a diagram showing a locked state. (B) shows a state where the fuel lid 20 is pushed by the push pin 64. FIG. 5 shows a state where the fuel lid 20 is locked in the fuel lid structure 10 according to the embodiment of the present invention. More specifically, FIG. 5A shows a state in the middle of the locking. (B) shows a locked state.

  In the fuel lid structure 10 according to the present embodiment, the fuel lid 20 is held in a state of being closed to the vehicle body by a lock mechanism 54 so as to close the fuel supply space 14 as shown in FIG. That is, when the fuel lid 20 is closed to the vehicle body, the claw portions 62 of the clip arms 60 provided on the clip 56 are locked to the groove-shaped locking portions 52 from the radially outer side of the nut 48. At this time, in this embodiment, three clip arms 60 are arranged at substantially equal intervals along the circumferential direction of the clip main body portion 58 so as to surround the push pin 64, so that the clip 56 is attached to the nut 48 by a three-point chuck. It will be in the state. At this time, the locking mechanism 54 exerts a locking force (fitting force) in the tangential direction (vehicle width direction) with respect to the fuel lid 20 in the closed position.

  From this state, when the fuel lid opener 84 disposed near the driver's seat is pulled, the lid cable 70 is pulled in the direction of the arrow R, whereby the entire bell crank 68 rotates in the direction of the arrow Q2 with the bent portion as the center. . Furthermore, when the bell crank 68 rotates in the direction of the arrow Q2 in this way, the push pin 64 slides outward in the vehicle width direction, and the push pin 64 is a portion on the proximal end side of the clip arm 60 (in this example, This portion is regarded as the central portion of the clip 56) and is pushed outward in the vehicle width direction (opening direction). As a result, as shown in FIG. 4B, the clip arm 60 is elastically deformed so as to fall with respect to the clip main body portion 58, and the interval between the claw portions 62 of the plurality of clip arms 60 facing the nut 48 is The claw part 62 of the clip arm 60 is detached from the groove-like locking part 52 of the nut 48 so as to be wider than the diameter dimension of the circumferential convex part 50 formed on the tip side.

  When the claw portion 62 of the clip arm 60 is detached from the groove-like locking portion 52 of the nut 48 in this way, the urging force in the opening direction by the push pin 64 at this time and the illustration provided in the hinge portion 24 are provided. The fuel lid 20 rotates in the opening direction (arrow P1 direction) by the urging force of the urging member that is not. As a result, the fuel lid 20 is rotated to a position where the fuel lid 20 is opened to the outside of the vehicle (this position is indicated by an imaginary line (two-dot chain line)), and the oil supply space 14 is exposed to the outside.

  As shown in FIGS. 4A and 4B, for example, ice 90 adheres and freezes between the fuel lid 20 and the body panel 12, and the resistance force of the ice 90 acts on the fuel lid 20. If it is stronger than the force, even if the claw portion 62 of the clip arm 60 is detached from the groove-like locking portion 52 of the nut 48, the fuel lid 20 does not rotate in the opening direction thereafter. However, in this case, the fuel lid opener 84 may be further pulled. In this way, the push pin 64 is further slid outward in the vehicle width direction, and the assist force by the push pin 64 breaks the ice 90 between the fuel lid 20 and the body panel 12 and opens the fuel lid 20. Can be rotated in the direction. In this case, when the push pin 64 reaches a predetermined sliding amount outward in the vehicle width direction, the stopper 66 of the push pin 64 comes into contact with the peripheral edge portion of the through hole 44 of the fixed wall portion 32, thereby the push pin. 64 is restricted from moving outward in the vehicle width direction.

  As described above, in the fuel lid structure 10 according to the present embodiment, when the push pin 64 is protruded from the vehicle body side to the fuel lid 20 side from the state where the fuel lid 20 is held closed by the vehicle body, the clip arm 60 is bent. As a result, the locking state between the nut 48 and the clip 56 is released, and further, the urging force in the opening direction by the push pin 64 is applied, and the fuel lid 20 rotates in the opening direction. Here, in the fuel lid structure 10 of the present embodiment, the push pin 64 is arranged coaxially with the lock mechanism 54 as shown in FIG. 2 as described above. Accordingly, since the offset between the lock mechanism 54 and the push pin 64 is reduced as compared with the prior art, even when the push pin 64 applies a biasing force to the fuel lid 20 in the opening direction, the fuel lid 20 as a whole, and thus the lock mechanism. The bending moment M (torsion) about the line L2 connecting the hinge mechanism 24 and the locking mechanism 54 acting on the hinge portion 24 and the hinge portion 24 is suppressed. As a result, it is possible to smoothly release the lock mechanism 54 and ensure the slidability of the hinge portion 24 (that is, the release of the lock mechanism 54 is smooth and the sliding of the hinge portion 24 is not easily inhibited). It becomes possible to open the fuel lid 20 smoothly.

  In particular, in the fuel lid structure 10 according to the present embodiment, as described above, the push pin 64 applies a biasing force in the opening direction of the fuel lid 20 to the central portion of the clip 56 (that is, the base end side portion of each clip arm). The lock is applied and the lock mechanism 54 is unlocked. Accordingly, the offset between the lock mechanism 54 and the push pin 64 becomes zero, and the line L2 connecting the lock mechanism 54 and the hinge part 24 acting on the entire fuel lid 20 and eventually the lock mechanism 54 and the hinge part 24 is centered. The bending moment M (torsion) is not biased. As a result, the lock mechanism 54 can be released more smoothly and the slidability of the hinge portion 24 can be ensured (that is, the lock mechanism 54 can be released more smoothly and the hinge portion 24 can slide). The fuel lid 20 can be opened more smoothly.

  Further, in the fuel lid structure 10 according to the present embodiment, after the clip arm 60 is bent by the push pin 64 to release the locking state between the claw portion 62 and the groove-like locking portion 52, the assist force of the push pin 64 is applied. The fuel lid 20 can be further given. Therefore, as shown in FIGS. 4A and 4B, even when ice 90 adheres between the fuel lid 20 and the body panel 12 and freezes, the fuel lid is assisted by the assist force of the push pin 64. The ice 90 between 20 and the body panel 12 can be broken, and the fuel lid 20 can be smoothly rotated in the opening direction.

  Further, in the fuel lid structure 10 according to the present embodiment, as shown in FIG. 2, the push pin 64 is orthogonal to the rotation axis L <b> 1 of the hinge portion 24 in a side view of the fuel lid 20 (in this case, a side view of the vehicle). It is arranged on an imaginary line L <b> 2 that passes through the central part of the hinge part 24. Therefore, when the push pin 64 applies an urging force to the fuel lid 20 in the opening direction of the fuel lid 20, it is possible to suppress a bending moment M to bend the rotating shaft L1 of the hinge portion 24 (in the imaginary line L2). The bending moment M decreases as the urging force application point of the push pin 64 approaches. Thereby, since the slidability of the hinge part 24 becomes better, the opening of the fuel lid 20 becomes smoother.

  Further, in the fuel lid structure 10 according to the present embodiment, as shown in FIG. 3, the push pin 64 is configured to penetrate the nut 48 provided on the vehicle body side of the lock mechanism 54. According to this configuration, when the push pin 64 penetrates the nut 48, the push pin 64 and the nut 48 can be downsized in the axial direction and the radial direction. Thereby, it becomes possible to reduce the restrictions with respect to arrangement | positioning of the fuel lid 20, and the freedom degree of the design around the fuel lid 20 improves.

  On the other hand, when the operator rotates the fuel lid 20 toward the vehicle body side (in the direction of arrow P2) from the position where the fuel lid 20 is opened to the outside of the vehicle, the fuel lid 20 is held closed to the vehicle body so as to close the fuel supply space 14. be able to. That is, when the operator rotates the fuel lid 20 from the position where the fuel lid 20 is opened to the outside of the vehicle toward the vehicle body (in the direction of the arrow P2), the clip arm 60 is positioned when the fuel lid 20 is in a position to close the fuel supply space 14. The tapered wall surface formed in the claw 62 contacts the edge of the circumferential convex portion 50 on the tip end side of the nut 48, and the clip arm 60 is expanded as shown in FIG. From this state, when the fuel lid 20 is further pushed in from the outside to the inside in the vehicle width direction (arrow P2 direction), the claw portion 62 of the clip arm 60 gets over the circumferential convex portion 50 of the nut 48. As a result, as shown in FIG. 5B, the clip arm 60 is returned to the original position by the elastic force of the clip arm 60 with respect to the clip main body 58, and the claw portion 62 of the clip arm 60 has a groove shape of the nut 48. The clip 56 and the nut 48 are locked by being locked by the locking portion 52.

  Further, when the fuel lid 20 is rotated from the position opened to the outside of the vehicle to the vehicle body side in this way, the fuel lid opener 84 is not pulled, so that the bell crank 68 is provided on the side wall portion 34 of the lock base 30. By being constantly urged in the direction of the arrow Q1 by the urging member that is not to be operated, the state is stopped at a predetermined rotation angle as shown in FIGS. 5 (a) and 5 (b). Further, along with this, the push pin 64 is pulled back inward in the vehicle width direction so as to be separated from the fuel lid 20. Therefore, as described above, even when the operator applies a biasing force to the fuel lid 20 toward the vehicle body to close the fuel lid 20, the push pin 64 biases the fuel lid 20 in the opening direction of the fuel lid 20. Is not granted. As a result, an extra closing force is not required when the fuel lid 20 is closed, and the operability when the fuel lid 20 is closed is improved.

  Further, in the fuel lid structure 10 according to the present embodiment, the fuel lid 20 is further pushed inward in the vehicle width direction from the outside from the state where the fuel lid 20 shown in FIG. Even so, the push pin 64 and the proximal end portion of the clip arm 60 are configured such that a predetermined clearance C is secured and the separated state is maintained. Therefore, when the fuel lid 20 is further pushed in from the outside toward the inside in the vehicle width direction, it is possible to prevent the clip arm 60 from being bent and the nut 48 and the clip 56 from being locked by being pushed by the push pin 64. Further, as shown in FIG. 5B, even when the nut 48 and the clip 56 are locked, a predetermined clearance C is secured between the push pin 64 and the proximal end portion of the clip arm 60. Since the separated state is maintained, it is possible to prevent the fuel lid 20 from being unexpectedly opened due to an external force acting on the fuel lid 20.

  Next, a modification of this embodiment will be described.

  In the above-described embodiment, the example in which the lid structure of the present invention is applied to the fuel lid structure 10 of the vehicle has been described, but it goes without saying that the lid structure may be applied to other lid opening / closing structures.

  In the above embodiment, as shown in FIG. 3, the lock mechanism 54 is configured by the nut 48 and the clip 56, and the nut 48 and the clip 56 are configured to be fitted. Is not limited to the configuration to be fitted. In addition, the lock mechanism 54 may be, for example, an electromagnetic lock type in which an electromagnet is provided on the vehicle body side and a metal member that is attracted to the electromagnet is provided on the lid side.

  In the above embodiment, as shown in FIG. 3, the nut 48 is provided on the vehicle body side and the clip 56 is provided on the fuel lid 20 side. However, the nut 48 is provided on the fuel lid 20 side, and the clip 56 is provided on the vehicle body side. May be.

  Moreover, in the said embodiment, as FIG. 2 showed, although the push pin 64 was arrange | positioned coaxially with the lock mechanism 54, you may make it as follows. In other words, for example, the bending moment M (torsion) around the line L2 connecting the locking mechanism 54 and the hinge portion 24 acting on the entire fuel lid 20 and the locking mechanism 54 and the hinge portion 24 is allowed. Thus, the push pin 64 may be disposed substantially coaxially with the lock mechanism 54 by shifting the position of the push pin 64 from the center of the lock mechanism 54.

  Further, in the above embodiment, as shown in FIG. 2, the virtual lid 20 is orthogonal to the rotation axis L <b> 1 of the hinge portion 24 in the side view (in this case, the vehicle side view) of the fuel lid 20 and passes through the center portion of the hinge portion 24. Although the push pin 64 is arranged on the line L2, for example, the push pin 64 is hinged from the virtual line L2 within the range where the push pin 64 overlaps with the support range A by the hinge part 24 of the fuel lid 20. It may be arranged so as to be shifted in the direction of 24 rotation axes L1.
