Description

The present invention relates to a fuel supply or charging port structure for a vehicle.

JP 1987-61824A discloses a vehicle fuel filler structure configured by connecting a rear fender panel and a wheel house with a fuel filler base.

2. Description of the Related Art In recent years, with the aim of reducing the weight of a vehicle, it has been studied to form an outer panel, which constitutes the surface of the vehicle body of the vehicle, from a resin. In such a case, the fuel supply port or charging port provided on the outer plate is also made of resin. When these ports and outer plates are made of resin, spot welding cannot be applied to iron parts, etc., and it is necessary to join the parts together using an adhesive, double-sided tape, or the like. When a fuel supply nozzle or a charging connector is connected to such a port from the outside, an external force such as a pressing force acts on the port constituent members. There is a need.

In JP1987-61824A, no consideration is given to forming the outer panel of the vehicle from resin, and no consideration is given to the strength and the like of the port structure made of resin.

<First embodiment>
FIG. 1 is a perspective view of a vehicle 100 having a charging port 10 according to the first embodiment.

A vehicle 100 shown in FIG. 1 is an electric vehicle that runs based on the charging power of a battery. An outer panel 20 forming the vehicle body surface of the vehicle 100 is made of resin in order to reduce the weight of the vehicle 100 . For example, in the vehicle 100 of the present embodiment, the front fender 2 forming the front side surface of the vehicle 100 and the rear fender (not shown) forming the rear side surface of the vehicle 100 are made of resin.

A charging port 10 used when charging a battery is provided on an outer panel 20 that constitutes the front fender 2 of the vehicle 100 .

FIG. 2 is a schematic configuration diagram of the charging port 10 with the cover member 4 opened.

As shown in FIG. 2 , charging port 10 includes charging connector 3 in a space formed by recessing a portion of outer plate 20 forming front fender 2 . The charging connector 3 is configured to be connectable to a power supply connector of a charging device placed on a charging stand or the like. The battery of the vehicle 100 is charged by connecting the charging connector 3 of the vehicle 100 and the power supply connector of the charging device.

A cover member 4 (lid) for opening and closing the port is arranged so as to be openable and closable at the opening of the front fender 2 (outer plate 20), which serves as the entrance portion of the charging port 10. As shown in FIG. A hinge member 4A for rotatably fixing the lid member 4 to the outer plate 20 is provided at the vehicle rear end of the lid member 4, and a port member 40, which will be described later, is provided at the vehicle front end of the lid member 4. An engaging portion 4B is provided which can be engaged with the locking mechanism 11 provided inside the main body portion 41 (see FIG. 3). When the cover member 4 is closed to block the charging port 10, the locking mechanism 11 and the engaging portion 4B are engaged. The engagement state between the locking mechanism 11 and the engaging portion 4B can be released by an unlocking operation using a screwdriver or the like. It shows a state where the

Next, details of the charging port 10 will be described with reference to FIGS. 3 to 5. FIG. FIG. 3 is a cross-sectional view of the charging port 10 in the vertical direction (vertical direction of the vehicle). FIG. 4 is a front view of the reinforcing plate 30 that constitutes the charging port 10. FIG. FIG. 5 is an enlarged view of the area R of FIG. 3 .

As shown in FIG. 3 , the outer plate 20 forming the front fender 2 forms a space as the charging port 10 by recessing a part of the outer plate 20 inside the vehicle body. The outer plate 20 is made of resin such as polypropylene.

The outer plate 20 includes an outer plate portion 21 , a side wall 22 extending from the outer plate portion 21 into the inside of the vehicle body, and a bottom plate 23 extending vertically from the side wall 22 . The outer plate 20 is an integrated structure made of a single plate made of resin.

The outer plate portion 21 is a member that forms part of the surface of the vehicle body such as the front fender 2 . The outer plate portion 21 has a substantially rectangular opening 21A as an entrance portion of the charging port 10 .

The side wall 22 extends from the open end of the outer plate portion 21 toward the inside of the vehicle body, that is, in the vehicle inside-outside direction (vehicle width direction). The side wall 22 is a member that defines the inner peripheral wall of the charging port 10, and is a substantially tubular wall member in which an upper side wall, a lower side wall, a front side wall, and a rear side wall are integrally formed.

The bottom plate 23 is a wall member formed at the inner end of the side wall 22 . The bottom plate 23 is a portion forming the bottom surface of the outer plate 20 and extends from the side wall 22 toward the inner space surrounded by the side wall 22 . The bottom plate 23 is formed with an opening 23A as a through hole penetrating in the vehicle body inward and outward directions. A port member 40 is attached to the bottom plate 23 .

The port member 40 is a bottomed cylindrical member made of resin such as polypropylene. The port member 40 is composed of a box-shaped body portion 41 with an opening on the outer side of the vehicle body, and a brim-shaped flange portion 42 formed so as to expand from the tip of the body portion 41 .

The port member 40 is arranged so that the body portion 41 enters the inside of the vehicle body through the opening 23A of the bottom plate 23 in a state where the flange portion 42 is connected to the surface side end surface (outer surface) of the bottom plate 23 of the outer plate 20. . The flange portion 42 and the bottom plate 23 may be joined by an adhesive, or may be joined by mechanical engagement means using an engagement projection and an engagement receiving portion. Alternatively, both members may be connected by bolts and nuts.

An opening 41A is formed in the bottom surface of the body portion 41 of the port member 40 so as to penetrate in the vehicle body inner and outer directions. The charging connector 3 is fixed to a vehicle body structure such as a chassis located inside the vehicle body from the port member 40, and is arranged so that the connector end face faces the outside of the vehicle body. In this embodiment, the port member 40 and the charging connector 3 are not directly connected, and a rubber sealing member (not shown) is provided between the outer peripheral surface of the charging connector 3 and the opening 41A of the port member 40. ) are placed. Charging connector 3 is electrically connected to battery 5 mounted on vehicle 100 .

In the present embodiment, the charging port 10 is configured by the resin-made outer plate 20 or the like. An external force such as a pressing force acts on the bottom plate 23 and the like of the plate 20, and there is a possibility that the outer plate 20 is largely deformed in the configuration of the outer plate 20 alone. Therefore, a reinforcing plate 30 is attached to the back surface of the outer plate 20 in order to make the strength and elongation of the outer plate 20 that constitutes a part of the charging port 10 appropriate.

As shown in FIGS. 3 and 4 , the reinforcing plate 30 is a member made of resin such as polypropylene, and serves to reinforce the outer plate 20 . Like the outer plate 20, the reinforcing plate 30 is also an integrated structure made of a single plate made of resin.

The reinforcing plate 30 includes an outer plate reinforcing portion 31 that reinforces the outer plate portion 21 of the outer plate 20, a side wall reinforcing portion 32 that reinforces the side wall 22 of the outer plate 20, and a bottom plate reinforcing portion that reinforces the bottom plate 23 of the outer plate 20. 33 and.

The outer plate reinforcing portion 31 is formed as a frame member extending along the outer plate portion 21 of the outer plate 20 .

The side wall reinforcing portion 32 extends along the side wall 22 of the outer plate 20 so as to enter the inside of the vehicle body from the inner peripheral end of the outer plate reinforcing portion 31 . The sidewall reinforcing portion 32 is a substantially tubular wall member in which an upper sidewall, a lower sidewall, a front sidewall, and a rear sidewall are integrally formed.

The bottom plate reinforcing portion 33 is a bottom surface extending from the inner end of the side wall reinforcing portion 32 along the bottom plate 23 . The bottom plate reinforcing portion 33 is formed with an opening 33A as a through hole for allowing the port member 40 to pass therethrough.

As shown in FIGS. 3 and 5 , the outer plate 20 and the reinforcing plate 30 are bonded between the outer plate portion 21 and the outer plate reinforcing portion 31 and between the bottom plate 23 and the bottom plate reinforcing portion 33 . They are glued together by an agent. In this manner, the outer plate portion 21 and the outer plate reinforcing portion 31 are adhered to each other through the first adhesive layer 51 , and the bottom plate 23 and the bottom plate reinforcing portion 33 are adhered to each other by the second adhesive layer 52 .

The thickness of the first and second adhesive layers 51 and 52 (adhesive) that bonds the outer plate 20 and the reinforcing plate 30 together is an important factor in determining the strength and elongation of the outer plate 20 . For example, if the first and second adhesive layers 51 and 52 are too thin, the distance between the outer plate 20 and the reinforcing plate 30 will be too small. Although the strength of the surrounding outer plate 20 is increased, the elongation of the outer plate 20 is reduced, and if a large external force is applied, there is a risk of plastic deformation of the port constituent member. On the other hand, if the first and second adhesive layers 51 and 52 are too thick, the distance between the outer plate 20 and the reinforcing plate 30 will be too large. The extension of the plate 20 increases, and it may become difficult to connect the power supply connector to the charging connector 3 .

Therefore, in the present embodiment, the reinforcement plate 30 is provided with a protrusion 34 as a gap adjusting member that defines the gap between the outer plate 20 and the reinforcement plate 30 for the purpose of making the adhesive thickness moderate. there is More specifically, on the surface of the outer plate reinforcing portion 31 of the reinforcing plate 30, a protrusion 34 is provided that abuts against the back surface of the outer plate portion 21 to define the interval between the outer plate 20 and the reinforcing plate 30 to be substantially constant. formed. On the other hand, the outer plate 20 has a flat surface shape at the portion facing the projection 34 of the reinforcing plate 30 and does not have a portion that engages or fits with the projection 34 .

As shown in FIG. 4, a plurality of protrusions 34 are formed on the surface of the outer plate reinforcing portion 31, and four protrusions 34 are formed in this embodiment. These four protrusions 34 are arranged side by side along the periphery of the opening 33A of the reinforcing plate 30, and are arranged at positions corresponding to the four corners of the rectangular opening 33A. The arrangement of these protrusions 34 is not limited to the arrangement shown in FIG. 4, and may be set at any position. Moreover, the protrusion 34 may be configured as a single linear protrusion surrounding the opening 33A.

The protrusion 34 may be formed at a position closer to the tip of the outer plate reinforcing portion 31 as long as it is on the outer plate reinforcing portion 31, or may be formed at a position closer to the side wall reinforcing portion 32 than the tip. As shown in FIG. 5, when the projection 34 is formed at a position closer to the side wall reinforcing portion 32, the projection 34 is arranged at a position closer to the member center of the reinforcing plate 30 itself. It becomes the structure which is easy to maintain a space|interval with the outer plate 20. As shown in FIG.

Furthermore, as shown in FIG. 5, the protrusion 34 is formed as a protrusion whose vertical cross section is curved in an arc shape. Further, the outer plate 20 around the charging port 10 is formed so as to be gently curved in the vertical direction, as indicated by the _one -dot chain line r1. In this way, the projection 34 of the gently curving outer plate 20 that abuts on the back surface of the outer plate portion 21 is configured such that the curvature of the projection 34 is larger than the curvature of the outer plate 20 (outer plate portion 21). ing. According to the mountain-shaped projection 34 having such a curved surface, the projection 34 can be brought into smooth contact with the back surface of the outer plate portion 21, and the appearance of the surface of the outer plate 20 at the contact portion is not adversely affected. do not have. Further, the projection 34 is likely to be in line contact with the outer plate 20 , and the configuration is such that the spacing between the reinforcing plate 30 and the outer plate 20 is easily maintained.

In the present embodiment, by interposing the projection 34 as a gap adjusting member between the outer plate 20 and the reinforcing plate 30, a predetermined gap can be maintained between the outer plate 20 and the reinforcing plate 30, The thickness of the adhesive (bonding layer) that fixes the reinforcing plate 30 to the outer plate 20 can be set to an appropriate thickness. The space between the side wall 22 of the outer plate 20 and the side wall reinforcing portion 32 of the reinforcing plate 30 is the space between the outer plate portion 21 and the outer plate reinforcing portion 31 and the space between the bottom plate 23 and the bottom plate reinforcing portion 33. are in communication with the space between them, respectively. Therefore, even if a large amount of adhesive is applied between the outer plate 20 and the reinforcing plate 30 , excess adhesive flows into the space between the side wall 22 and the side wall reinforcing portion 32 . Thus, the space between the side wall 22 and the side wall reinforcing portion 32 functions as an adhesive storage chamber for collecting excess adhesive.

In this embodiment, the outer plate 20 and the reinforcing plate 30 are adhered by the first and second adhesive layers 51 and 52 as described above. If the coefficient of linear expansion and the coefficient of linear expansion of the reinforcing plate 30 are significantly different, a difference in thermal expansion occurs between the parts depending on the temperature of the outside air, and the strain increases at the bonding points of the outer plate 20 and the like, resulting in abnormal appearance. There is a risk of

Therefore, as shown in Table 1 below, comparative examples in which the material of the outer plate 20 and the material of the reinforcing plate 30 are different, and Examples 1 to 5 were examined for their appearance. The comparative example is an example in which the material of the outer plate is polypropylene and the material of the reinforcing plate is steel. On the other hand, in the materials of the outer plate 20 and the reinforcing plate 30 of Examples 1 to 5, PP means polypropylene, and GF30 and TD35 described in parentheses mean fillers added to polypropylene. . GF30 means 30% weight percent glass fiber relative to polypropylene and TD35 means 35% weight percent talc relative to polypropylene.

In the case of the comparative example shown in Table 1, it was confirmed that defects in appearance occurred due to the difference in coefficient of linear expansion between the outer plate and the reinforcing plate. However, in Examples 1 to 5 in which both the outer plate 20 and the reinforcing plate 30 are made of resin, the difference in the coefficient of linear expansion between the outer plate 20 and the reinforcing plate 30 is within the general temperature range of the outside air to which the vehicle 100 is exposed. Almost no appearance defects caused by As a result of the knowledge and various experiments based on these Examples 1 to 5, from the viewpoint of suppressing the appearance defect caused by the difference in the linear expansion coefficient, the linear expansion coefficient of the outer plate 20 and the linear expansion coefficient of the reinforcing plate 30 is preferably 40×10 ⁻⁶ /° C. or less.

In addition, regarding Examples 1 to 5, the strength of the port structure member when the reinforcing plate 30 is attached to the outer plate 20 is also examined. It was confirmed that the strength of the port structure member was basically secured by attaching the resin reinforcing plate 30 to the resin outer plate 20 . However, as shown in Examples 1, 3, and 4, when the reinforcing plate 30 was made of reinforcing fiber such as glass fiber or resin such as polypropylene containing talc, the strength was particularly good. As a result of findings from Examples 1 to 5 and various experiments, the reinforcing plate 30 is preferably made of resin containing reinforcing fibers (glass fibers, carbon fibers, etc.) or talc.

According to the port structure according to the first embodiment described above, the following effects can be obtained.

The charging port structure according to this embodiment includes a resin-made outer plate 20 , a port member 40 , a charging connector 3 , and a resin-made reinforcing plate 30 . The outer plate 20 includes an outer plate portion 21 forming part of the surface of the vehicle body, a side wall 22 extending from the outer plate portion 21 toward the inside of the vehicle body, and extending from the side wall 22 toward an inner space surrounded by the side wall. and a bottom plate 23 having an opening 23A. The port member 40 is connected to the surface side of the bottom plate 23 and enters the inside of the vehicle body through the opening 23A. The charging connector 3 is arranged to face the outside of the vehicle body through an opening 41A formed in the port member 40 . The reinforcing plate 30 includes an outer plate reinforcing portion 31 extending along the outer plate portion 21, a side wall reinforcing portion 32 extending from the outer plate reinforcing portion 31 along the side wall 22, and a bottom plate extending from the side wall reinforcing portion 32. a bottom plate reinforcing portion 33 extending along 23 and having an opening 33A through which the port member 40 passes. A protrusion 34 is formed on the outer plate reinforcing portion 31 to define the interval between the outer plate 20 and the reinforcing plate 30 by coming into contact with the back surface of the outer plate 20 . The outer plate portion 21 and the outer plate reinforcing portion 31, and the bottom plate 23 and the bottom plate reinforcing portion 33 are bonded with an adhesive.

In this embodiment, the protrusions 34 of the reinforcing plate 30 can define a predetermined gap between the outer plate 20 and the reinforcing plate 30, and the adhesive layer 51 between the outer plate portion 21 and the outer plate reinforcing portion 31 Also, the thickness of the adhesive layer 52 between the bottom plate 23 and the bottom plate reinforcing portion 33 can be set to a desired thickness. Thereby, it is possible to set the strength and elongation of the outer plate 20 and the port member 40 within an appropriate range against the external force acting when connecting the power supply connector. In addition, since the port member 40 is connected to the surface side of the bottom plate 23 and enters the inside of the vehicle body through the opening 23A, the port member 40 can be easily assembled to the outer plate 20. Assemblability can be improved.

Further, according to the port structure of this embodiment, the cover member 4 for opening and closing the port is arranged on the outer plate 20 . Therefore, it is also possible to set the strength and elongation of the outer plate 20 and the port member 40 within appropriate ranges against the external force generated when the lid member 4 is closed.

Further, the protrusion 34 formed on the outer plate reinforcing portion 31 of the reinforcing plate 30 is formed at a position closer to the side wall reinforcing portion 32 in the outer plate reinforcing portion 31 . As a result, the projection 34 is arranged at a position closer to the center of the member of the reinforcing plate 30 itself, so that the distance between the reinforcing plate 30 and the outer plate 20 is easily maintained at a predetermined distance.

Furthermore, a plurality of protrusions 34 are provided along the periphery of the opening 33A of the bottom plate reinforcing portion 33 . By arranging a plurality of protrusions 34 side by side around the opening 33A in this way, it is possible to attach the reinforcing plate 30 to the back surface of the outer plate 20 in parallel without rattling.

Furthermore, the protrusion 34 is formed as a protrusion with a curved cross section in the longitudinal direction. More specifically, the outer plate 20 is also formed to gently curve in the vertical direction of the vehicle, and the curvature of the projection 34 is configured to be larger than the curvature of the outer plate 20 . According to the projection 34 having such a curved surface, the projection 34 can be brought into smooth contact with the rear surface of the outer plate portion 21 without adversely affecting the appearance of the surface of the outer plate 20 at the contact portion. Furthermore, the protrusions 34 are likely to be in line contact with the outer plate 20, so that the distance between the reinforcing plate 30 and the outer plate 20 is easily maintained at a predetermined distance.

Furthermore, the space between the side wall 22 of the outer plate 20 and the side wall reinforcing portion 32 of the reinforcing plate 30 is the space between the outer plate portion 21 and the outer plate reinforcing portion 31 and the space between the bottom plate 23 and the bottom plate reinforcing portion 33. are in communication with the space between them, respectively. Therefore, even if a large amount of adhesive is applied between the outer plate 20 and the reinforcing plate 30 , excess adhesive flows into the space between the side wall 22 and the side wall reinforcing portion 32 . Therefore, such surplus adhesive is prevented from overflowing to the vehicle body surface side. Further, the outer plate 20 and the reinforcing plate 30 are bonded not only by the first and second adhesive layers 51 and 52, but also by the adhesive leaked between the outer plate portion 21 and the outer plate reinforcing portion 31. Therefore, the bonding strength between both members can be increased.

Furthermore, the outer plate 20 has a flat surface shape at a portion facing the projection 34 of the reinforcing plate 30, and does not have a portion that engages or fits with the projection 34. As shown in FIG. If an engaging portion or a fitting portion is formed in a portion of the resin-made outer plate 20 that abuts on the projection 34, a sink mark may occur on the surface of the outer plate due to molding shrinkage or the like at the engaging portion or the fitting portion during molding of the outer plate. may occur and the appearance properties may deteriorate. In the outer plate 20 of the present embodiment, since the contact portion with the protrusion 34 is a flat surface, the appearance of the outer plate 20 described above does not deteriorate.

<Second embodiment>
The charging port 10 according to the second embodiment will be described with reference to FIGS. 6 and 7. FIG. FIG. 6 is a longitudinal partial cross-sectional view of the charging port 10 according to the second embodiment. FIG. 7 is a front view of the reinforcing plate 30 that constitutes the charging port 10. FIG.

In the first embodiment, the projections 34 are formed only on the outer plate reinforcing portion 31 of the reinforcing plate 30 as the interval adjusting member. In addition, projections 35 are also formed on the bottom plate reinforcing portion 33 of the reinforcing plate 30 .

As shown in FIG. 6, in this embodiment, two types of projections 34 and 35 are provided for one reinforcing plate 30, and these projections 34 and 35 come into contact with the back surface of the outer plate 20, thereby A predetermined gap is maintained between the plate 20 and the reinforcing plate 30 .

As shown in FIG. 7 , the protrusions 35 formed on the bottom plate reinforcing portion 33 also have the same shape as the protrusions 34 of the outer plate reinforcing portion 31 . That is, the protrusion height of the protrusion 35 is the same as the protrusion height of the protrusion 34 . A plurality of projections 35 are formed on the surface of the bottom plate reinforcing portion 33, and four projections 35 are formed in this embodiment. These four projections 35 are arranged side by side along the periphery of the opening 33A of the reinforcing plate 30, and are arranged at positions substantially corresponding to the centers of the long and short sides of the rectangular opening 33A. More specifically, the protrusions 34 of the outer plate reinforcing portion 31 and the protrusions 35 of the bottom plate reinforcing portion 33 are arranged with their positions shifted in the circumferential direction of the opening 33A of the bottom plate reinforcing portion 33 .

The arrangement of these protrusions 34 and 35 is not limited to the arrangement shown in FIG. 7, and may be set at any position. Moreover, the protrusions 34 and 35 may be configured as a single linear protrusion surrounding the opening 33A.

The protrusion 35 may be formed at a position closer to the opening 33A of the outer plate reinforcing portion 31 as long as it is on the bottom plate reinforcing portion 33, or may be formed at a position closer to the side wall reinforcing portion 32 than the opening 33A. . As shown in FIG. 6, when the projection 35 is formed at a position closer to the opening 33A, the projection 35 is arranged at a position closer to the center of the member of the reinforcing plate 30 itself. 20 is easily maintained.

Also in the port structure of this embodiment, the same combination of materials for the outer plate 20 and the reinforcing plate 30 as in Examples 1 to 5 in Table 1 can be employed.

According to the port structure according to the second embodiment described above, the following effects can be obtained.

In the port structure according to the present embodiment, a projection 34 is formed on the outer plate reinforcing portion 31 of the reinforcing plate 30 and a projection 35 is formed on the bottom plate reinforcing portion 33 of the reinforcing plate 30 . These protrusions 34 and 35 allow the reinforcing plate 30 to be attached to the rear surface of the outer plate 20 without rattling, and the distance between the outer plate 20 and the reinforcing plate 30 can be maintained at a more constant distance. As a result, the thickness of the adhesive layer 51 between the outer plate portion 21 and the outer plate reinforcing portion 31 and the thickness of the adhesive layer 52 between the bottom plate 23 and the bottom plate reinforcing portion 33 can be made more constant. Also, the strength and elongation of the port member 40 can be set with higher accuracy.

A plurality of protrusions 35 of the bottom plate reinforcing portion 33 are provided along the periphery of the opening 33A of the bottom plate reinforcing portion 33, similarly to the protrusions 34 of the outer plate reinforcing portion 31. As shown in FIG. By arranging the plurality of protrusions 34 and 35 side by side around the opening 33A in this way, it is possible to attach the reinforcing plate 30 to the back surface of the outer plate 20 in parallel without rattling.

Further, the protrusion 34 of the outer plate reinforcing portion 31 and the protrusion 35 of the bottom plate reinforcing portion 33 are arranged with their positions shifted in the circumferential direction of the opening 33A of the bottom plate reinforcing portion 33 . According to such a configuration, even if the projection heights of the projections 34 and 35 vary somewhat, rattling is unlikely to occur when attached to the back surface of the outer plate 20, and the gap between the outer plate 20 and the reinforcing plate 30 is reduced. The desired spacing can be maintained as much as possible.

Although the embodiments of the present invention have been described above, the above embodiments merely show a part of application examples of the present invention, and the technical scope of the present invention is not limited to the specific configurations of the above embodiments. do not have.

For example, as shown in FIG. 8, on the back surface (inner surface) of the reinforcing plate 30 in the first embodiment, there are provided extending along the respective back surfaces of the outer plate reinforcing portion 31, the side wall reinforcing portion 32, and the bottom plate reinforcing portion 33. Provided ribs 36 may be formed. A plurality of ribs 36 may be formed along the periphery of the opening 33</b>A of the bottom plate reinforcing portion 33 . Such ribs 36 are employed as necessary to increase the strength and elongation of charging port 10 . The rib 36 can be used not only in the charging port 10 of the first embodiment, but also in the charging port 10 of the second embodiment.

Further, as shown in FIG. 8 , in the reinforcing plate 30 , one or more through holes 32A may be formed in the side wall reinforcing portion 32 for the purpose of reducing the weight of the reinforcing plate 30 . The through hole 32A can be used not only in the charging port 10 of the first embodiment, but also in the charging port 10 of the second embodiment.

Although one charging connector 3 is arranged in the charging port 10 in the above-described first and second embodiments, the number of charging connectors arranged is not limited to one. For example, the charging port 10 may have two connectors, a normal charging connector capable of charging from a household power source and a quick charging connector capable of charging from a quick charger.

Further, in the first and second embodiments, the port is a charging port for the electric vehicle 100, but the port may be a fuel supply port for a vehicle that uses gasoline, light oil, or the like as fuel. When the port is a fuel supply port, the fuel supply portion is positioned inside the port through the opening 41A of the port member 40, and the fuel supply port of the fuel supply portion is arranged to face the outside of the vehicle body.

Furthermore, the charging port 10 or the fuel supply port may be formed at any position of the vehicle as required, instead of being formed in the front fender of the vehicle.
