Description

  The present invention mainly relates to a fuel lid structure for a vehicle.

  The fuel lid structure for a vehicle is, for example, a small open state in which the lid portion is slightly opened (half-opened) with respect to the vehicle body portion, and a fully open state in which the lid portion is fully opened with respect to the body portion and the fuel filler nozzle can be inserted into the filler port. In addition, the lid portion can be closed (see Patent Documents 1 and 2).

  For example, the lid portion is locked by a lock mechanism in the closed state, and turns to a small open state when the lock is released. This is realized by applying an urging force to the lid portion by the elastic member. In addition, the lid portion in the small open state is further rotated, for example, manually by the user to be in the fully open state. At this time, the lid portion has an action of returning to the small open state or an action of attempting to enter the fully open state. Occurs. These are also realized by the biasing force by the elastic member.

  By the way, the rotation characteristics required for the lid portion are different between the rotation region of the lid portion from the closed state to the small open state and the rotation region of the lid portion from the small open state to the fully open state. The urging force may need to be adjusted or changed for each region.

  The present invention has been made with the recognition of the above problem as an opportunity, and an object thereof is to make it possible to adjust the urging force applied to the rotation of the lid portion according to the rotation region of the lid portion.

  One aspect of the present invention relates to a fuel lid structure, and the fuel lid structure is attached to a lid portion rotatably supported via a shaft portion with respect to a vehicle body portion, and the lid portion and the body portion. The lid portion is provided with a lid-side support portion that rotatably supports one end portion of the elastic member, and the body portion includes the elastic member. A vehicle body side support portion that rotatably and slidably supports the other end portion of the lid portion is provided, and a portion of the lid portion relative to the body portion that is unidirectional from a predetermined position is a first region. When the portion on the other direction side from the predetermined position is set as the second region, the elastic member is configured such that when the lid portion rotates in the first region, the one end portion becomes the lid-side support portion. Rotate against When the other end portion rotates with respect to the vehicle body side support portion and the elastic member expands and contracts, and the lid portion rotates in the second region, the one end portion becomes the lid side support portion. The other end portion slides with respect to the vehicle body side support portion while maintaining a relative position to the vehicle body, and the elastic member expands and contracts to apply a biasing force to the rotation of the lid portion.

  According to the present invention, the urging force given to the rotation of the lid portion can be adjusted according to the rotation region of the lid portion.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Each drawing is a schematic diagram showing the structure or configuration of the embodiment, and the dimensions of each member shown in the drawings do not necessarily reflect actual ones. Moreover, in each figure, the same reference number is attached | subjected to the same member or the same component, and description is abbreviate | omitted about the overlapping content hereafter.

  FIG. 1 is a perspective view showing a vehicle body structure of a vehicle 1 according to the embodiment. The vehicle 1 includes a fuel lid structure ST on the side of the vehicle body. In the drawing, to facilitate understanding of the structure, an X axis, a Y axis, and a Z axis that are orthogonal to each other are shown (the same applies to FIGS. 2 to 6 described later). The X direction corresponds to the longitudinal direction of the vehicle body, the Y direction corresponds to the vehicle width direction, and the Z direction corresponds to the vertical direction of the vehicle body. In the present specification, expressions such as front / rear, left / right (side), and up / down indicate a relative positional relationship with respect to the vehicle body. For example, expressions such as “front” and “front” correspond to the + X direction, and expressions such as “rear” and “rear” correspond to the −X direction. Similarly, expressions such as the inside of the vehicle body (inside the vehicle) / the outside of the vehicle body (outside of the vehicle) indicate the relative positional relationship with respect to the vehicle body.

  FIG. 2 is a perspective view showing the fuel lid structure ST. The fuel lid structure ST includes a lid portion 3 and an elastic member 4. The lid portion 3 is supported so as to be rotatable with respect to the body portion 2 of the vehicle 1. The elastic member 4 is attached to the lid portion 3 and the body portion 2, and is provided between them in the present embodiment, and applies an urging force to the rotation of the lid portion 3 with respect to the body portion 2.

  The body part 2 includes an adapter 21 and a support base 22. The adapter 21 is formed in a shape in which the outside of the vehicle is opened, for example, a cup shape or a bowl shape, and has a fuel filler opening (not shown) therein. Although details will be described later, the support base 22 is provided with a vehicle body side support portion 221, and in this embodiment, a long hole (slit hole) is provided as the vehicle body side support portion 221.

  The lid portion 3 includes a lid body 30, a shaft portion 31, and a lid side support portion 32. The lid body 30 is a panel or a plate material for sealing the inside of the adapter 21 from the outside. The lid portion 3 is rotatably supported with respect to the body portion 2 via the shaft portion 31. The lid side support portion 32 is integrated with the shaft portion 31 and will be described later in detail, but the lid side support portion 32 is provided with an insertion hole 321.

  The elastic member 4 is rotatably supported by the lid side support portion 32 at one end portion and is rotatably and slidably supported by the vehicle body side support portion 221 at the other end portion. Although details will be described later, the elastic member 4 applies a biasing force to the rotation of the lid portion 3 relative to the body portion 2 by such a configuration.

  The state in which the lid portion 3 is rotated is a state in which the lid portion 3 is closed (closed state), a state in which the lid portion 3 is slightly opened (smallly open state), and a body portion that is larger than the small open state. 2 is an open state (fully open state). By making the lid portion 3 fully open, it becomes possible to access the fuel filler opening in the adapter 21, that is, it is possible to insert the fuel filler nozzle into the fuel filler opening for refueling. While refueling is not performed, the lid portion 3 is generally maintained in a closed state, and in this state, the lid main body 30 seals the inside of the adapter 21 so as to form a substantially continuous surface with the exterior panel of the body portion 2. To do. The lid portion 3 is maintained in a closed state by being locked, and is in a small open state by an urging force from the elastic member 4 in response to the release of the lock. For example, a user who performs refueling can perform refueling after manually opening the lid portion 3 in the small open state, and return the lid portion 3 to a closed state after refueling is completed. Although details will be described later, the urging force by the elastic member 4 is also involved between the operation of switching from the small open state to the fully open state and the operation of returning from the fully open state to the closed state.

  The small open state and the fully open state are both states in which the fuel filler opening in the adapter 21 is opened. However, in this embodiment, the small open state is an open state in which the fuel filler nozzle cannot be inserted into the fuel filler opening. Is a state in which the oil supply nozzle can be inserted into the oil supply port after being opened larger than the small open state. Here, the fully open state is a state in which the body portion 2 is substantially completely opened, or a state in which the lid portion 3 is located at one end of the rotatable region or the rotation allowable region. It is not limited to this.

  FIG. 3 is a perspective view showing the structure of the lid portion 3. In the present embodiment, the lid portion 3 further includes a connection portion 33 and a lock hole 34. The connecting portion 33 is a portion (may be referred to as an arm portion or the like) that connects the shaft portion 31 and the lid main body 30, and in this embodiment is curved and extended toward the vehicle interior side. The lock hole 34 is provided on the inner side of the lid main body 30, and a lock mechanism which will be described later is inserted through the lock hole 34 to fix the lid main body 30, thereby maintaining the lid portion 3 in a closed state.

  FIG. 4 is a perspective view showing the structure inside the adapter 21 with the lid main body 30, the connecting portion 33, etc. not shown. In addition to the fuel filler opening, an opening 211 through which the connecting portion 33 of the lid portion 3 is inserted is provided in the adapter 21. When the lid portion 3 is rotated to open the fuel filler port, the connecting portion 33 is formed to pass through the opening 211 toward the vehicle outer side, and when the lid portion 3 is pivoted to close the fuel filler port, the connection portion is formed. Reference numeral 33 denotes a shape passing through the opening 211 toward the vehicle interior side.

  FIG. 5 is a perspective view showing the structure of the elastic member 4. The elastic member 4 includes an elastic force generator 40, an end (one end) 41, and an end (other end) 42. The elastic force generator 40 generates an elastic force so that the distance between the end portions 41 and 42 is a natural length. In the present embodiment, the elastic member 4 is a torsion spring in which the elastic force generator 40 is configured in a coil shape. Therefore, referring to FIG. 5, the elastic force generator 40 generates an elastic force in the circumferential direction with the Z direction as the rotation axis at the center in the XY plane.

  The end portion 41 is an arm portion extending substantially in one direction from the elastic force generating portion 40 and includes a shaft portion 411 and a locking portion 412. The shaft portion 411 is a portion bent in the Z direction in the figure, and the details will be described later, but the shaft portion 411 passes through the insertion hole 321 (see FIGS. 2 to 4) of the lid-side support portion 32. Thus, the end portion 41 is fixed to the lid side support portion 32 so as to be rotatable. The locking portion 412 is a portion bent in the Z direction at a position farther from the shaft portion 411 from the elastic force generating portion 40, and will be locked to the lid-side support portion 32 as will be described in detail later. Thereby, the rotation range with respect to the lid side support part 32 of the said edge part 41 is controlled.

  The end portion 42 is an arm portion extending in a direction different from the end portion 41 from the elastic force generating portion 40 and includes a shaft portion 421. The shaft portion 421 is a portion bent in the Z direction in the figure, and will be described in detail later, but the shaft portion 421 is fitted in a long hole (see FIGS. 2 and 4) as the vehicle body side support portion 221. Thus, the end portion 42 is supported so as to be rotatable and slidable with respect to the vehicle body side support portion 221 (that is, relative to the support base 22).

  With such a configuration, the elastic member 4 can apply a biasing force to the rotation of the lid portion 3. The elastic force generation unit 40 may be configured to generate an elastic force that makes the distance between the end portions 41 and 42 a natural length, and is not limited to the shape of this example. For example, as another embodiment, the elastic force generator 40 may be a bar-like or plate-like member bent in a zigzag manner.

  FIG. 6A shows a state when the fuel lid structure ST is viewed in the Z direction in the closed state in which the lid portion 3 is closed. FIG. 6B is a cross-sectional view of the fuel lid structure ST on the XY plane at a position shifted from the elastic member 4 in the Z direction and passing through the shaft portion 31 and the connection portion 33. As can be seen from FIG. 6A, the end portion 41 is fixed to the lid-side support portion 32 so that the shaft portion 411 passes through the insertion hole 321. The locking portion 412 is in contact with and locked with the lid side support portion 32 (the locking portion 412 may be referred to as a contact portion or the like). Further, as can be seen from FIG. 6B, the lid main body 30 can be fixed by the lock mechanism using the lock hole 34, whereby the lid portion 3 is maintained in the closed state.

  As described above, when the lock by the lock mechanism is released, the lid portion 3 in the closed state receives a biasing force from the elastic member 4 and is in a small open state. Thereafter, the user can manually and under the urging force of the elastic member 4, the lid portion 3 in the small open state can be fully opened or closed. The mechanism at the time of opening and closing the lid portion 3 in such a fuel lid structure ST will be described in detail below with reference to FIGS.

  FIG. 7 shows a simplified model for explaining the mechanism of the opening / closing mechanism of the fuel lid structure ST. In this simple model, the shaft portion 31 and the lid-side support portion 32 have the same structure as described above (see FIG. 3), while the lid body 30 and the connection portion 33 for the lid main body 30 are easy to understand. 32 is shown as a rod-shaped member integral with the member 32. Further, the vehicle body side support portion 221 which is a long hole is shown in a form directly provided on the body portion 2 for the sake of simplification of the drawing.

  In the drawing, the lid portion 3 at the position P0 corresponds to the closed state, the lid portion 3 at the position P1 corresponds to the small open state, and the lid portion 3 at the position P3 corresponds to the fully open state. To do. The position illustrated by the position P2 corresponds to an intermediate position between the small open state and the fully open state, and will be described later in detail, but is a position where the biasing force is balanced. In the present specification, these positions P0, P1, P2, and P3 may be expressed as a closing position P0, a small opening position P1, an intermediate position P2, and a full opening position P3, respectively.

  In the drawing, the rotation region of the lid portion 3 from the position P1 to the position P3 among the rotatable regions of the lid portion 3 is indicated as a region R1, and the lid portion from the position P1 to the position P0 The rotation region is indicated as region R2.

  The lid portion 3 is locked by the lock mechanism 9 at the closed position P0, so that the lid portion 3 can be maintained in the closed state. In the closed state, the distance between the end portions 41 and 42 is smaller than the natural length, that is, the elastic force generating unit 40 generates an elastic force that acts so that the end portions 41 and 42 are separated from each other. is doing. When the lock by the lock mechanism 9 is released, the lid portion 3 receives the urging force of the elastic member 4 and rotates in the region R2, and stops at the small opening position P1. The unlocking is performed, for example, when a passenger such as a driver operates a predetermined lever in the vehicle. The user can manually rotate the lid portion 3 at the small open position P1 in the region R1 and move it to the fully open position P3 via the intermediate position P2. Alternatively, the user can manually rotate the lid portion 3 at the small opening position P1 in the region R2 and move it to the closing position P0.

  FIG. 8 shows a simplified model of the lid portion 3 in the small open state (position P1). In the small open state, the elastic member 4 is locked with the locking portion 412 coming into contact with the lid-side support portion 32 and the shaft portion 421 is one end of the vehicle body-side support portion 221 (distant from the end portion 41). The side end).

  In the small open state, the distance between the end portions 41 and 42 is smaller than the natural length, that is, the elastic force generating unit 40 generates an elastic force that acts to separate the end portions 41 and 42 from each other. It has occurred. Here, in the small open state, the shaft portion 421 is in contact with the one end portion of the vehicle body side support portion 221 at the end portion 42, while the locking portion 412 is in contact with the lid side support portion 32 at the end portion 41. The rotation of the end portion 41 with respect to the lid side support portion 32 is limited. Therefore, the distance between the end portions 41 and 42 is fixed without being further increased regardless of the elastic force generated by the elastic force generating unit 40.

  Although details will be described later, as shown in the drawing, the shaft passes through the rotation shaft of the shaft portion 411 and the rotation shaft of the shaft portion 421 and is orthogonal to the rotation shaft of the shaft portion 411 (or the shaft portion 421). A straight line to be made is assumed to be a virtual line L1. Further, as shown in the drawing, a virtual line L2 is defined as a straight line passing through the rotation axis of the shaft portion 421 and the rotation shaft of the shaft portion 31 and orthogonal to the rotation axis of the shaft portion 421. Further, as shown in the figure, a straight line passing through the rotation axis of the shaft portion 421, orthogonal to the virtual line L2, and orthogonal to the rotation axis of the shaft portion 421 is defined as a virtual line L3. At this time, the elastic force generation part 40 is on the opposite side of the axis part 31 with respect to the virtual line L1 from the viewpoint of the axis part 31 in the axial direction (that is, in a plane orthogonal to the axial direction of the axis part 31). Arranged to be located.

  Further, although details will be described later, the vehicle body side support portion 221 that is a long hole is positioned on the same side as the elastic force generation portion 40 with respect to the virtual line L2 at the viewpoint in the axial direction of the shaft portion 31 and is virtual. It is provided so as to be located on the same side as the shaft portion 31 with respect to the line L3. In relation to the region R221 formed by the imaginary lines L2 and L3 shown in the drawing, the long holes as the vehicle body side support portions 221 are provided so that most or substantially all are located in the region R221. It only has to be done. From another viewpoint, the long hole only needs to extend from the rotation shaft of the shaft portion 421 in the small open state toward the region R221.

  FIG. 9 shows a simplified model of the lid portion 3 at the intermediate position P2 (a state between the small open state and the full open state). Here, a state when the user manually moves the lid portion 3 from the small opening position P1 to the intermediate position P2 is shown. When the lid portion 3 is in the intermediate position P2, the rotation shaft of the shaft portion 411 is located on a straight line passing through the rotation shaft of the shaft portion 31 and the rotation shaft of the shaft portion 421.

  While the lid portion 3 moves from the small opening position P1 to the intermediate position P2, the shaft portion 421 rotates at one end portion (see FIG. 8) of the vehicle body side support portion 221, and the locking portion 412 moves from the lid side support portion 32. By separating, the lid portion 3 rotates in the region R <b> 1 according to the rotation axis of the shaft portion 31. Accordingly, in the elastic member 4, the end portion 41 rotates with respect to the lid side support portion 32 according to the rotation axis of the shaft portion 411, and the end portion 42 follows the rotation axis of the shaft portion 421. It rotates with respect to the support part 221. At this time, since the distance between the end portions 41 and 42 is smaller than that in the small open state, the elastic force generating unit 40 exerts a large elastic force in the direction in which the end portions 41 and 42 are separated from each other. Will occur in the form. Therefore, when the lid portion 3 is located between the small opening position P1 and the intermediate position P2, the elastic member 4 applies an urging force to the lid portion 3 so that the lid portion 3 moves toward the small opening position P1. That is, when the user releases his / her hand from the lid portion 3 while moving from the small opening position P1 to the intermediate position P2, the lid portion 3 returns to the small opening position P1 by the urging force from the elastic member 4.

  FIG. 10 shows a simplified model of the lid portion 3 in the fully opened state (position P3). Here, a state when the user manually moves the lid portion 3 from the intermediate position P2 to the fully open position P3 is shown.

  The elastic member 4 is elastic in the direction in which the end portions 41 and 42 are separated from each other as in the above-described movement from the small open position P1 to the intermediate position P2 between the intermediate position P2 and the fully open position P3 (see FIG. 9). Generating power. Therefore, while the lid portion 3 moves from the intermediate position P2 to the fully open position P3, the elastic member 4 applies an urging force to the lid portion 3 so that the lid portion 3 moves toward the fully open position P3. That is, when the user releases his / her hand from the lid portion 3 while moving from the intermediate position P2 to the fully open position P3, the lid portion 3 moves to the fully open position P3 by the urging force from the elastic member 4.

  In the simple model referred to here, the lid side support portion 32 is in contact with the elastic force generating portion 40, so that the rotation of the lid portion 3 according to the rotation axis of the shaft portion 411 is limited, and the lid portion 3 is in a fully open state. However, the present invention is not limited to the above embodiment. For example, in the embodiment described with reference to FIGS. 2 to 6, when the body portion 2 and / or the lid portion 3 opens the lid portion 3 to the fully open position, the body portion 2 and the lid portion 3 are stoppers not shown. You may comprise so that rotation of the lid part 3 may be restrict | limited by contacting a part. Thereby, the lid part 3 can be made into a fully open state appropriately.

  This will be described in more detail as follows. As described above, in the state where the lid portion 3 is at the intermediate position P2, the rotation shaft of the shaft portion 411 is located on a straight line passing through the rotation shaft of the shaft portion 31 and the rotation shaft of the shaft portion 421 (see FIG. 9). Therefore, when the lid portion 3 moves from the position P2 to the position P1 side, the urging force of the lid portion 3 is generated so that the lid portion 3 moves toward the small opening position P1. On the other hand, when the lid portion 3 moves from the position P2 to the position P3 side, the urging force of the lid portion 3 is generated so that the lid portion 3 moves toward the fully open position P3 (see FIG. 10). From this point of view, the intermediate position P2 includes an urging force of the elastic member 4 that moves the lid portion 3 toward the small opening position P1 and an urging force of the elastic member 4 that moves the lid portion 3 toward the fully open position P3. It is a stable and balanced position.

  FIG. 11 shows a simplified model of the lid portion 3 in the closed state (position P0). Here, a state when the user manually moves the lid portion 3 from the small opening position P1 to the closing position P0 is shown.

  As described above (see FIG. 8), in the small open state (position P <b> 1), the elastic member 4 has the end portion 42 so that the shaft portion 421 contacts the one end portion of the vehicle body side support portion 221 and the end portion 41 has the locking portion. 412 is engaged with the lid-side support portion 32 to restrict the rotation of the end portion 41 relative to the lid-side support portion 32. When the lid portion 3 moves from the small open state toward the position P0, the rotation of the end portion 41 is limited, that is, the relative position of the end portion 41 with respect to the lid-side support portion 32 is maintained. The lid portion 3 rotates in the region R2. At this time, in the lid portion 3, the shaft portion 31 serves as a fulcrum, the lid body 30 serves as a power point, and the insertion hole 321 serves as an action point, so that the lid portion 3 rotates. Accordingly, in the elastic member 4, the locking portion 412 serves as a fulcrum, the shaft portion 411 passing through the insertion hole 321 serves as a power point, and the elastic force generation portion 40 serves as an action point, so that the elastic member 4 is the body. It becomes the form which moves to the vehicle outside with respect to the part 2. FIG. As a result, the end portion 42 moves to the vehicle outer side with respect to the body portion 2 as the shaft portion 421 slides in a long hole as the vehicle body side support portion 221.

  Since the elastic member 4 generates an elastic force so that the distance between the end portions 41 and 42 increases while the lid portion 3 moves from the small opening position P1 to the closing position P0, the elastic member 4 A biasing force is applied to the lid portion 3 so that the portion 3 moves toward the small opening position P1. That is, when the user releases his / her hand from the lid portion 3 while moving from the small opening position P1 to the closing position P0, the lid portion 3 returns to the small opening position P1 by the urging force from the elastic member 4. In the present embodiment, when the lid portion 3 reaches the closing position P0, the lock mechanism 9 (see FIG. 7) is locked, and the lid portion 3 is maintained in the closed state.

  When the lid portion 3 rotates in the region R2, the locking portion 412 has a straight line connecting the shaft portion 411 and the shaft portion 31 and a straight line connecting the locking portion 412 and the shaft portion 31 orthogonal to each other. For example, it may be provided so as to intersect at an angle of about 80 to 100 °. Accordingly, the locking portion 412 appropriately regulates the rotation of the end portion 41 with respect to the lid side support portion 32, and the end portion 42 can be appropriately slid by the vehicle body side support portion 221, so that the region R 2 of the lid portion 3 Can be appropriately realized. Further, when the lid portion 3 rotates in the region R1, the locking portion 412 is in a position where it is difficult to interfere with other members.

  Further, when the lid portion 3 rotates in the region R <b> 2, a considerable load is applied to the lid-side support portion 32 at a portion that contacts the locking portion 412. Therefore, it is preferable that the lid-side support portion 32 is formed so that the portion in contact with the locking portion 412 is thicker than the peripheral portion. Thereby, the part which touches can be made high intensity | strength, and the lid side support part 32 can be endured with the said load.

  7 to 11, in the present embodiment, in the end portion 41, the extending direction of the portion from the shaft portion 411 to the locking portion 412 is the portion from the elastic force generating portion 40 to the shaft portion 411. It is inclined with respect to the extending direction. However, these may be parallel to each other, and their inclination angle may be set based on the shape of the lid-side support portion 32.

  As described above, according to the present embodiment, when the lid portion 3 rotates in the region R <b> 1, the end portion 42 rotates with respect to the lid side support portion 32 and the end portion 42 with respect to the vehicle body side support portion 221. As the elastic member 4 expands and contracts by rotating, an urging force is applied to the rotation of the lid portion 3. On the other hand, when the lid portion 3 rotates in the region R2, the end portion 42 maintains a relative position with respect to the lid-side support portion 32, and the end portion 42 slides with respect to the vehicle body-side support portion 221, thereby elastic member. As 4 expands and contracts, a biasing force is applied to the rotation of the lid portion 3.

  The biasing force by the elastic member 4 when the lid portion 3 rotates in the region R1 can be adjusted (or changed) by the spring constant of the elastic force generating portion 40. For example, when the elastic member 4 is a torsion spring, the urging force by the elastic member 4 can be adjusted based on the number of windings, winding pitch, wire diameter, winding diameter, material, and the like.

  On the other hand, the urging force in the region R <b> 2 can be adjusted by the vehicle body side support portion 221 that allows the end portion 42 to slide in addition to the elastic modulus of the elastic member 4. In the present embodiment, the adjustment of the urging force by the vehicle body side support portion 221 can be realized by changing the extending direction of the long hole as the vehicle body side support portion 221. The long hole is located on the same side as the elastic force generation unit 40 with respect to the virtual line L2 and is located on the same side as the shaft part 31 with respect to the virtual line L3 from the viewpoint in the axial direction of the shaft part 31. That is, it may be provided so as to be substantially located in the region R221 (see FIG. 8). For example, in the example of the present embodiment, the urging force is increased when the extending direction of the long hole is brought close to the virtual line L2, and is attached when the extending direction of the long hole is brought close to the virtual line L3. The power becomes smaller.

  FIG. 12 shows another simple model of the fuel lid structure ST as an example. In this example, the vehicle body side support portion 221 is provided on a support base 22 ′ configured to be rotatable with respect to the body portion 2. The support base 22 ′ can be fixed with the vehicle body side support portion 221 in a desired direction. The support base 22 'may be fixed so that the direction of the long hole as the vehicle body side support portion 221 is in the region R221 (see FIG. 8). When the support 22 'is rotated in the direction of the arrow a1, the urging force in the region R2 is increased, and when the support base 22' is rotated in the direction of the arrow a2, the urging force is decreased. In this example, for example, by adjusting the direction of the vehicle body side support portion 221 and fixing the support base 22 ′ at the time of manufacturing the fuel lid structure ST, it is possible to realize a desired rotation characteristic of the lid portion 3.

  Therefore, according to the present embodiment, with a relatively simple configuration, a part of the pivotable region of the lid portion 3 (region R1 in the present embodiment) and another part (region R2 in the present embodiment). The urging force applied to the rotation of the lid portion 3 can be individually adjusted. In addition, although the said long hole was made into the substantially straight groove | channel here, this long hole may be a curved groove | channel and the urging | biasing force by the elastic member 4 can further be adjusted also with the shape of a long hole.

  Moreover, in this embodiment, the elastic force generation part 40 is arranged so that it may be located in the opposite side to the axial part 31 with respect to the virtual line L1 in the viewpoint in the axial direction of the axial part 31 (refer FIG. 8). . Thereby, even when the lid portion 3 rotates in any of the regions R1 and R2, the elastic force generating portion 40 is less likely to interfere with the body portion 2 (for example, the adapter 21 (see FIG. 6 and the like)). It can be appropriately pivotable. This also contributes to an improvement in the degree of freedom in designing the fuel lid structure ST and / or the body part 2.

  Further, in the present embodiment, the elastic member 4 is in a contracted state from the natural length when the lid portion 3 rotates in any of the regions R1 and R2. In general, in the structure in which the elastic member 4 is contracted from the natural length and in the extended state, for example, the structure in which the elastic member 4 is in the natural length is used in the small open state, the body portion 2 of the lid portion 3 is used. There is a possibility that the position (or the degree of opening) with respect to will fluctuate. On the other hand, in the present embodiment, the state in which the elastic member 4 is in the natural length is not applied to any of the small open state, the full open state, and the closed state, and thus the variation in the position of the lid portion 3 can be suppressed. .
