Fig. 12 shows a cross section taken along line XII-XII in Fig. 11.

[0012] As shown in FIG. 1, a vehicle charging device 1 of this embodiment is placed on a floor 100 of a parking space where a vehicle is parked. The vehicle charging device 1 has a housing 2. The housing 2 has a base portion 2c fixed to the floor portion 100. The base portion 2c is a base portion of the vehicle charging device 1 and is formed, for example, from a metal plate. The housing 2 has a sliding cover 2a and a rotating cover 2b. The covers 2a and 2b cover the devices housed in the internal space of the housing 2 from above.

[0013] As shown in FIG. 2, the vehicle charging device 1 has a sliding body 3 arranged inside the housing 2. As shown in FIG. 3, the sliding body 3 has a first sliding body 3A and a second sliding body 3B. The first sliding body 3A is slidably supported by the base portion 2c. The first sliding body 3A is movable in a second direction W relative to the base portion 2c. The second sliding body 3B is slidably supported by the first sliding body 3A. The second sliding body 3B is movable in a first direction L relative to the first sliding body 3A. The first direction L and the second direction W are horizontal directions. In addition, when the floor surface of the floor portion 100 is inclined, it is preferable that the first direction L and the second direction W are parallel to the floor surface of the floor portion 100.

[0014] The first direction L corresponds to the front-rear direction of the vehicle 200 to be charged. The second direction W corresponds to the width direction of the vehicle 200. The vehicle 200 is positioned at a charging position where it is charged by the vehicle charging device 1 while moving forward or backward along the first direction L. In the illustrated vehicle charging device 1, the first direction L is the longitudinal direction of the housing 2. The second direction W is the lateral direction of the housing 2 and is perpendicular to the first direction L.

[0015] 2, the vehicle charging device 1 includes a sensor 4, a connector 5, a support member 6, a connecting mechanism 7, and an arm 8. The vehicle charging device 1 further includes a first drive mechanism 10, a second drive mechanism 20, a third drive mechanism 30, and a fourth drive mechanism 40.

[0016] 5, the connector 5 is fitted into an inlet 210 disposed in the vehicle 200. The inlet 210 is disposed at the bottom of the vehicle 200. The connector 5 is fitted into the inlet 210, thereby being connected to a battery of the vehicle 200.

[0017] The sensor 4 is used to detect the position of the inlet 210. The sensor 4 may be a distance measuring sensor, a sensor that captures an image and detects an object in the image, or other position detection sensor. The sensor 4 may include a plurality of sensors with different detection methods. The sensor 4 in this embodiment is a laser sensor that detects the distance to a reflecting object by using a laser light. The sensor 4 emits a laser light in a predetermined direction and receives the laser light reflected by the object.

[0018] The sensor 4 is disposed on the second slide body 3B and moves together with the second slide body 3B. The sensor 4 illustrated in FIG. 2 has a first sensor 4A, a second sensor 4B, and a third sensor 4C. The three sensors 4A, 4B, and 4C are arranged in this order in the second direction W. The second sensor 4B emits laser light toward the upper side in the vertical direction Z. The vertical direction is a direction perpendicular to both the first direction L and the second direction W, and corresponds to the vehicle vertical direction of the vehicle 200. The first sensor 4A and the third sensor 4C emit laser light in an oblique direction inclined with respect to the vertical direction Z.

[0019] The connector 5 is a charging connector that charges the battery of the vehicle 200. The connector 5 has a terminal for charging. The vehicle charging device 1 of this embodiment is configured so that the position of the connector 5 can be moved in a first direction L, a second direction W, and an up-down direction Z.

[0020] The first driving mechanism 10 is a mechanism for moving the connector 5 in a first direction L. The first driving mechanism 10 has a first motor 11 and a gear 12. The first motor 11 is disposed on the second sliding body 3B. The gear 12 is disposed on the output shaft of the first motor 11, and meshes with a rack gear disposed on the first sliding body 3A. The first motor 11 can move the second sliding body 3B and the connector 5 in the first direction L by rotating forward and backward.

[0021] The second drive mechanism 20 is a mechanism for moving the connector 5 in the second direction W. The second drive mechanism 20 has a second motor 21 and a gear 22. The second motor 21 is disposed on the first sliding body 3A. The gear 22 is disposed on the output shaft of the second motor 21. The gear 22 meshes with a rack gear disposed on the base portion 2c of the housing 2 via a reduction gear. The second motor 21 can move the first sliding body 3A and the second sliding body 3B in the second direction W by rotating forward and reverse.

[0022] The third drive mechanism 30 is a mechanism for moving the connector 5 in the up-down direction Z. The connector 5 is connected to the second slide body 3B via an arm 8, a support member 6, and a connecting mechanism 7. The arm 8 is a plate-shaped member and has a first end 81 and a second end 82. The first end 81 is connected to the support member 6. The second end 82 is rotatably supported by the second slide body 3B. In other words, the arm 8 is rotatable around the second end 82 as a rotation center. The arm 8 moves the support member 6 up and down by rotating.

[0023] The vehicle charging device 1 of this embodiment has a first arm 8A and a second arm 8B. The first arm 8A and the second arm 8B extend in a first direction L and face each other in a second direction W. Second ends 82 of the two arms 8A and 8B are connected to each other via a shaft. Therefore, the two arms 8A and 8B rotate in conjunction with each other.

[0024] The support member 6 is connected to a first end 81 of the first arm 8A and a first end 81 of the second arm 8B. The support member 6 is a plate-shaped member and extends in the second direction W. The support member 6 is journaled by the first end 81 of the arm 8 so as to be rotatable relative to the arm 8.

[0025] The connecting mechanism 7 connects the connector 5 and the support member 6, and is configured to allow a change in the posture of the connector 5. As shown in FIG. 4, the connecting mechanism 7 has a universal joint 71 and a spring 72. The universal joint 71 and the spring 72 are disposed between the support member 6 and the connector 5, and extend in a first direction L. One ends of the universal joint 71 and the spring 72 are connected to the support member 6, and the other ends of the universal joint 71 and the spring 72 are connected to the connector 5.

[0026] A bearing may be disposed between the universal joint 71 and the connector 5. In this case, the bearing allows the connector 5 to rotate about the central axis in the first direction L. When a bearing is provided, the connector 5 is rotatable relative to the universal joint 71.

[0027] The universal joint 71 of this embodiment allows the connector 5 to change in posture in two rotational directions. More specifically, the universal joint 71 allows the connector 5 to rotate about a central axis Wx in the second direction W. The universal joint 71 further allows the connector 5 to rotate about a central axis Zx in the up-down direction Z. The universal joint 71 is, for example, a cross joint.

[0028] The spring 72 includes a first spring 72A and a second spring 72B. The first spring 72A and the second spring 72B are disposed on both sides in the second direction W with the universal joint 71 therebetween. The first spring 72A and the second spring 72B apply a spring force to the connector 5 to return the connector 5 to a neutral position in the rotational direction.

[0029] The third driving mechanism 30 moves the connector 5 in the up-down direction Z by rotating the arm 8. As shown in FIG. 2, the third driving mechanism 30 has a third motor 31, a first gear 32, and a second gear 33. The third motor 31 is disposed on the second slide body 3B. The first gear 32 is disposed on the output shaft of the third motor 31. The second gear 33 is connected to a shaft connecting the two arms 8A, 8B, and meshes with the first gear 32. The third motor 31 rotates forward and backward to rotate the arm 8.

[0030] The fourth drive mechanism 40 is configured to change the angle θ of the connector 5. The angle θ is an inclination angle of the connector 5 with respect to the first direction L. The fourth drive mechanism 40 has a fourth motor 41, a first sprocket 42, and a pair of second sprockets 43. The fourth motor 41 is disposed on the second slide body 3B. The first sprocket 42 is disposed on the output shaft of the fourth motor 41. The second sprocket 43 is disposed coaxially with the shaft connecting the arms 8A and 8B, and rotates relative to the shaft. An endless chain is wound around the first sprocket 42 and the second sprocket 43. A third sprocket 44 is disposed on the support member 6. An endless chain is wound around the second sprocket 43 and the third sprocket 44. The fourth motor 41 rotates forward and backward to rotate the support member 6 relative to the arms 8A and 8B. The rotation of the support member 6 changes the angle θ of the connector 5.

[0031] 6, the vehicle charging equipment 1 has a first wiring structure 60A, a second wiring structure 60B, and a third wiring structure 60C. The wiring structures 60A, 60B, and 60C are structures for wiring electric wires that supply power, signals, and the like to each device of the vehicle charging equipment 1.

[0032] The first wiring structure 60A is arranged between the base portion 2c and the first sliding body 3A. As shown in Fig. 6 and Fig. 7, the first wiring structure 60A has a first exterior member 61, a second exterior member 62, a first electric wire 63, and a second electric wire 64.

[0033] The first exterior member 61 and the second exterior member 62 are flexible tubular members. The first exterior member 61 and the second exterior member 62 are molded, for example, from an insulating synthetic resin. The first exterior member 61 and the second exterior member 62 are formed by connecting a plurality of tubular portions 65 as shown in FIG. 8, for example. The tubular portions 65 are tubular members into which electric wires 63, 64 can be inserted. The cross-sectional shape of the tubular portions 65 is, for example, rectangular. Two adjacent tubular portions 65 are connected by an axis 65a so as to be rotatable relative to each other.

[0034] 6 and 7, the first exterior member 61 has a first end 61a and a second end 61b. The second exterior member 62 has a first end 62a and a second end 62b. The first ends 61a, 62a are fixed to the base portion 2c. The second ends 61b, 62b are fixed to the first sliding body 3A. The second ends 61b, 62b move in the second direction W following the first sliding body 3A.

[0035] The first wiring structure 60A is arranged to have a curved portion 66. The curved portion 66 is curved in a convex U-shape toward the second direction W. The second exterior member 62 is arranged side by side with the first exterior member 61 so as to be located radially inward relative to the first exterior member 61 at the curved portion 66. In other words, the second exterior member 62 is arranged in a region surrounded by the first exterior member 61. At the curved portion 66, a first curved portion 61c is formed in the first exterior member 61, and a second curved portion 62c is formed in the second exterior member 62. The second curved portion 62c is located radially inward relative to the first curved portion 61c. The first ends 61a, 62a and the second ends 61b, 62b open toward the same side in the second direction W.

[0036] As shown in Fig. 9, the first exterior member 61 is configured to have an inner diameter R at the first curved portion 61c. The movable range of the tubular portion 65 of the first exterior member 61 is restricted to achieve the inner diameter R at the first curved portion 61c. The second exterior member 62 is configured to have an inner diameter r at the second curved portion 62c. The movable range of the tubular portion 65 of the second exterior member 62 is restricted to achieve the inner diameter r at the second curved portion 62c. The inner diameter R of the first curved portion 61c is larger than the inner diameter r of the second curved portion 62c.

[0037] The second end portions 61b, 62b of the first exterior member 61 and the second exterior member 62 are connected to the first sliding body 3A. That is, the second end portions 61b, 62b slide in the second direction W with respect to the base portion 2c together with the first sliding body 3A. The movement of the second end portions 61b, 62b changes the position of the curved portion 66 in the first wiring structure 60A. More specifically, when the second end portions 61b, 62b move toward the first side W1 in the second direction W, the position of the curved portion 66 moves to a position closer to the second end portions 61b, 62b. On the other hand, when the second end portions 61b, 62b move toward the second side W2 in the second direction W, the position of the curved portion 66 moves to a position closer to the first end portions 61a, 62a.

[0038] 10, the first exterior member 61 and the second exterior member 62 in the embodiment each have a rectangular cross-sectional shape. At least one first electric wire 63 is inserted into the first exterior member 61. The inner diameter R of the first exterior member 61 is determined according to the outer diameter D1 of the first electric wire 63. When multiple first electric wires 63 are inserted into the first exterior member 61, the inner diameter R is determined according to the outer diameter D1 of the first electric wire 63 having the largest diameter.

[0039] At least one second electric wire 64 is inserted into the second exterior member 62. The inner diameter r of the second exterior member 62 is determined according to the outer diameter D2 of the second electric wire 64. When a plurality of second electric wires 64 are inserted into the second exterior member 62, the inner diameter r is determined according to the outer diameter D2 of the second electric wire 64 having the maximum diameter. The outer diameter D2 of the second electric wire 64 is smaller than the outer diameter D1 of the first electric wire 63. That is, the first electric wire 63 having a relatively large outer diameter D1 is inserted into the first exterior member 61, and the second electric wire 64 having a relatively small outer diameter D2 is inserted into the second exterior member 62. Here, the outer diameter D2 of the second electric wire 64 being smaller than the outer diameter D1 of the first electric wire 63 means, for example, that the outer diameter D2 of the second electric wire 64 having the maximum diameter is smaller than the outer diameter D1 of the first electric wire 63 having the maximum diameter.

[0040] The cross-sectional shape of the second exterior member 62 is a rectangle in which a width Wd1 in a direction along the axis Ax of the curved portion 66 is greater than a width Wd2 in a radial direction. In other words, the cross-sectional shape of the second exterior member 62 is a rectangle with the vertical direction Z as the longitudinal direction. This cross-sectional shape ensures both the necessary inner radius r of the second exterior member 62 and a sufficient cross-sectional area.

[0041] The cross-sectional shape of the first exterior member 61 is a rectangle in which a width Wd3 in a direction along the axis Ax of the curved portion 66 is greater than a width Wd4 in a radial direction. In other words, the cross-sectional shape of the first exterior member 61 is a rectangle with the vertical direction Z as the longitudinal direction. This cross-sectional shape ensures both the necessary inner diameter R of the first exterior member 61 and a sufficient cross-sectional area.

[0042] In the first wiring structure 60A of the present embodiment, the flattening ratio F2 of the second exterior member 62 is larger than the flattening ratio F1 of the first exterior member 61. The flattening ratios F1 and F2 are calculated by the following formulas (1) and (2). F1 = (Wd3 - Wd4) / Wd3 (1) F2 = (Wd1 - Wd2) / Wd1 (2)

[0043] As described above, the degree of flattening of the second exterior member 62 is greater than the degree of flattening of the first exterior member 61. In other words, the second exterior member 62 has a cross-sectional shape that is elongated compared to the first exterior member 61. Since the small-diameter second electric wire 64 is inserted into the second exterior member 62, it is possible to reduce the radial width Wd2. The flattening ratio F2 of the second exterior member 62 is determined based on the inner diameter R to be secured in the first exterior member 61, the inner diameter r to be secured in the second exterior member 62, and the cross-sectional area required for the second exterior member 62.

[0044] According to the first wiring structure 60A of the present embodiment, the second wiring structure 60B is disposed by utilizing the space inside the first wiring structure 60A. This makes it possible to minimize the area for wiring the first electric wire 63 and the second electric wire 64 inside the housing 2.

[0045] 6, the second wiring structure 60B and the third wiring structure 60C are disposed at the end of the first sliding body 3A in the second direction W. The first electric wire 63 and the second electric wire 64 are connected to the device of the second sliding body 3B via the second wiring structure 60B or the third wiring structure 60C.

[0046] The second wiring structure 60B has a third exterior member 91 and an electric wire 92. The third exterior member 91 is a flexible tubular member. The third exterior member 91 is formed by connecting a plurality of tubular portions 65, for example. The electric wire 92 inserted into the third exterior member 91 is, for example, the first electric wire 63. The first electric wire 63 includes, for example, an electric wire for power supply connected to a terminal of the connector 5.

[0047] The second wiring structure 60B is arranged to have a curved portion 93. The curved portion 93 is curved in a convex U-shape toward the first direction L. The third exterior member 91 has a first end 91a and a second end 91b. The first end 91a is connected to the first sliding body 3A. The second end 91b is connected to the second sliding body 3B. Therefore, when the second sliding body 3B moves relative to the first sliding body 3A along the first direction L, the second wiring structure 60B follows the second sliding body 3B while changing the position of the curved portion 93. When the electric wire 92 is the first electric wire 63, the third exterior member 91 is configured so that the curved portion 93 has an inner diameter R.

[0048] The third wiring structure 60C has a fourth exterior member 94 and an electric wire 95. The fourth exterior member 94 is a flexible tubular member. The fourth exterior member 94 is formed by connecting a plurality of tubular portions 65, for example. The electric wire 95 inserted into the fourth exterior member 94 is, for example, the second electric wire 64. The second electric wire 64 includes, for example, a communication line or a small-diameter power supply line.

[0049] The third wiring structure 60C is arranged to have a curved portion 96. The curved portion 96 is curved in a convex U-shape toward the first direction L. The fourth exterior member 94 has a first end portion 94a and a second end portion 94b. The first end portion 94a is connected to the first sliding body 3A. The second end portion 94b is connected to the second sliding body 3B. Therefore, when the second sliding body 3B moves relative to the first sliding body 3A along the first direction L, the third wiring structure 60C follows the second sliding body 3B while changing the position of the curved portion 96. When the electric wire 95 is the second electric wire 64, the fourth exterior member 94 is configured so that the curved portion 96 has an inner radius r.

[0050] In the vehicle charging device 1 of this embodiment, the second wiring structure 60B and the third wiring structure 60C are arranged at different ends in the second direction W. This allows efficient arrangement of electric wires. For example, electric wires can be routed to the motors 11, 31, 41 and the connector 5 from both sides in the second direction W.

[0051] In this embodiment, the first electric wire 63 is inserted into the third exterior member 91, and the second electric wire 64 is inserted into the fourth exterior member 94. This minimizes the arrangement space for the fourth exterior member 94. As a comparative example, a part of the first electric wire 63 is inserted into the third exterior member 91, and another part of the first electric wire 63 is inserted into the fourth exterior member 94. In this case, it is necessary for the curved portion 96 of the fourth exterior member 94 to have an inner diameter R. In contrast, when the electric wire 95 inserted into the fourth exterior member 94 is the second electric wire 64, it is sufficient for the curved portion 96 to have the inner diameter r.

[0052] The vehicle charging device 1 of this embodiment has a load-bearing structure described below because it is placed in a parking space for the vehicle 200. The load-bearing structure of this embodiment can reduce the frictional resistance when the first sliding body 3A and the second sliding body 3B move, while ensuring resistance to the load of the vehicle 200.

[0053] As shown in FIG. 11, the load-bearing structure 300 has a first support column 310, a second support column 320, a third support column 330, a first buffer member 340, and a second buffer member 350. The first support column 310, the second support column 320, and the third support column 330 are columns that support a load Ld in the vertical direction Z, and are, for example, metal members. The first buffer member 340 and the second buffer member 350 are members that are disposed in the gap between two members. The first buffer member 340 and the second buffer member 350 have a rigidity that can support the load Ld. The first buffer member 340 and the second buffer member 350 are preferably members that have a small coefficient of friction. The first buffer member 340 and the second buffer member 350 are formed of, for example, synthetic resin or metal.

[0054] The first support 310 is disposed between the base portion 2c and the cover 2d of the housing 2. The cover 2d is a member that covers the base portion 2c from above. The cover 2d is disposed above the first sliding body 3A and the second sliding body 3B, and covers the first sliding body 3A and the second sliding body 3B. The first support 310 is fixed to, for example, at least one of the cover 2d or the base portion 2c. The base portion 2c supports the first support 310 and the cover 2d from below against the load Ld.

[0055] The second support 320 is disposed between the cover 2d and the first sliding body 3A. The second support 320 is fixed to, for example, either the cover 2d or the first sliding body 3A. The first buffer member 340 is a plate-shaped member and is interposed between the base portion 2c and the first sliding body 3A. The first buffer member 340 is disposed at a position facing the second support 320 with the first sliding body 3A therebetween. In other words, the base portion 2c supports the first buffer member 340 and the first sliding body 3A from below against the load Ld. The first sliding body 3A supports the second support 320 and the cover 2d from below against the load Ld.

[0056] The third support 330 is disposed between the cover 2d and the second slide body 3B. The third support 330 is fixed to, for example, either the cover 2d or the second slide body 3B. The second buffer member 350 is a plate-shaped member and is interposed between the first slide body 3A and the second slide body 3B. The second buffer member 350 is disposed at a position facing the third support 330 with the second slide body 3B therebetween. The first buffer member 340 is disposed at a position facing the second buffer member 350 with the first slide body 3A therebetween. The first slide body 3A supports the second buffer member 350, the second slide body 3B, the third support 330, and the cover 2d from below against the load Ld.

[0057] In this way, the load-bearing structure 300 supports the load Ld at multiple points by the multiple support columns 310, 320, 330 and the multiple buffer members 340, 350. In other words, the load-bearing structure 300 distributes the transmission path of the load Ld between the cover 2d and the base portion 2c. This improves the load-bearing performance of the vehicle charging device 1.

[0058] 12, a plurality of second support columns 320 are arranged along the second direction W. The second support columns 320 may be arranged at both ends of the first slider 3A in the second direction W. The second support column 320 may further be arranged in the center of the second direction W.

[0059] The first buffer member 340 is disposed on, for example, the base portion 2c and held by the base portion 2c. The base portion 2c may have a recess for holding the first buffer member 340. When the first buffer member 340 is held by the base portion 2c, the first buffer member 340 extends in the movable range of the second support column 320 in the second direction W. The illustrated first buffer member 340 is disposed so as to always face the second support column 320 when the second support column 320 moves in the second direction W together with the first slide body 3A. Thus, the load-bearing structure 300 of this embodiment can stably support the load Ld acting on the second support column 320.

[0060] The first buffer member 340 may be disposed on the lower surface of the first sliding body 3A and fixed to the first sliding body 3A. In this case, the load-bearing structure 300 may be configured such that both the first buffer member 340 and the second support column 320 move together with the first sliding body 3A.

[0061] The second buffer member 350 may be disposed on the lower surface of the second slide body 3B and fixed to the second slide body 3B. In this case, the load-bearing structure 300 may be configured such that both the second buffer member 350 and the third support column 330 move together with the second slide body 3B.

[0062] The second buffer member 350 may be disposed on the first slide body 3A and held by the first slide body 3A. The first slide body 3A may have a recess for holding the second buffer member 350. When the second buffer member 350 is held by the first slide body 3A, the second buffer member 350 may extend in the movable range of the third support column 330 in the first direction L, as shown in FIG. 13. The second buffer member 350 shown in FIG. 13 is disposed so as to always face the third support column 330 when the third support column 330 moves in the first direction L together with the second slide body 3B. Therefore, the load-bearing structure 300 in FIG. 13 can stably support the load acting on the third support column 330. Note that a plurality of first buffer members 340 may be disposed for the second buffer member 350. For example, as shown in FIG. 13, the first buffer members 340 may be disposed at both ends of the second buffer member 350 in the first direction L.

[0063] As described above, the vehicle charging device 1 of this embodiment has the base portion 2c, the sliding body 3, and the first wiring structure 60A. The base portion 2c is fixed to the floor portion 100. The sliding body 3 has a connector 5 that fits with the inlet 210 arranged in the vehicle 200 arranged thereon, and is slidably supported by the base portion 2c. The first wiring structure 60A is arranged between the base portion 2c and the first sliding body 3A. The first wiring structure 60A has a curved portion 66 curved in a U-shape, and follows the movement of the first sliding body 3A while changing the position of the curved portion 66. The first wiring structure 60A of this embodiment follows the movement of the first sliding body 3A while changing the position of the U-shaped curved portion 66, thereby reducing the space for the wiring structure. For example, it is possible to minimize the space required to absorb the excess length.

[0064] The first wiring structure 60A of the present embodiment has a first exterior member 61, a first electric wire 63, a second exterior member 62, and a second electric wire 64. The first electric wire 63 is inserted into the first exterior member 61, and the second electric wire 64 is inserted into the second wiring structure 60B. The outer diameter D2 of the second electric wire 64 is smaller than the outer diameter D1 of the first electric wire 63. The second exterior member 62 is arranged side by side with the first exterior member 61 so as to be located radially inward relative to the first exterior member 61 at the curved portion 66. In the vehicle charging device 1 of the present embodiment, the second exterior member 62 is arranged radially inward relative to the first exterior member 61 by utilizing the difference between the inner diameter R that the first exterior member 61 should have and the inner diameter r that the second exterior member 62 should have. This makes it possible to reduce the space required for wiring the electric wires 63 and 64.

[0065] The cross-sectional shape of the second exterior member 62 in this embodiment is a rectangle in which a width Wd1 along the axial direction of the curved portion 66 is wider than a width Wd2 in the radial direction. In the curved portion 66, the outside of the second exterior member 62 is restricted by the inner diameter R of the first exterior member 61. Furthermore, the second exterior member 62 is restricted by an inner diameter r in the curved portion 66. The second exterior member 62 in this embodiment has a vertically elongated rectangular cross-sectional shape as described above, and thereby meets the radial dimensional standard.

[0066] The cross-sectional shape of the first exterior member 61 in this embodiment is a rectangle in which a width Wd3 along the axial direction of the curved portion 66 is greater than a width Wd4 in the radial direction. The flattening ratio F2 of the second exterior member 62 is greater than the flattening ratio F1 of the first exterior member 61. The above-mentioned relationship in flattening ratio is realized by inserting the second electric wire 64, which has a relatively small diameter, into the second exterior member 62. The vehicle charging device 1 in this embodiment can reduce the space required for routing the electric wires 63, 64.

[0067] The vehicle charging device 1 of this embodiment has a cover 2d that covers the base portion 2c, and a load-bearing structure 300. The load-bearing structure 300 is disposed between the base portion 2c and the cover 2d. The sliding body 3 has a first sliding body 3A and a second sliding body 3B. The first sliding body 3A is supported by the base portion 2c, and slides in a second direction W relative to the base portion 2c. The second sliding body 3B is supported by the first sliding body 3A, and slides in a first direction L relative to the first sliding body 3A.

[0068] The load-bearing structure 300 has a second support column 320, a third support column 330, a first buffer member 340, and a second buffer member 350. The second support column 320 is disposed between the cover 2d and the first sliding body 3A. The third support column 330 is disposed between the cover 2d and the second sliding body 3B. The first buffer member 340 is a buffer member interposed between the first sliding body 3A and the base portion 2c. The second buffer member 350 is a buffer member interposed between the second sliding body 3B and the first sliding body 3A. The load-bearing structure 300 can appropriately support the load Ld received by the cover 2d by the multiple support columns.

[0069] In the vehicle charging device 1, the number, arrangement, and angle of the sensors 4 are not limited to the illustrated number, arrangement, and angle. For example, the vehicle charging device 1 can obtain the position of a protrusion (not shown) and the yaw angle α, roll angle γ, and pitch angle β of the inlet 210 by at least one sensor 4.

[0070] Incidentally, in the housing 2, the cover 2b described above covers the base portion 2c on the vehicle entry starting point side of the vehicle charging device 1 (i.e., the vehicle entry starting point side which is the entry starting point of the vehicle 200 entering along the first direction L). As shown in Fig. 14, the housing 2 includes a pair of side covers 2e fixed to the base portion 2c at the vehicle entry starting point side with a gap between them in the second direction W. The cover 2b is disposed in a state of being sandwiched between the pair of side covers 2e.

[0071] In the vehicle charging device 1, the second sliding body 3B is disposed in the space between the base portion 2c, the cover 2b, and the pair of side covers 2e. The second sliding body 3B slides in the first direction L between a storage position where it is stored between the pair of side covers 2e and a pull-out position where it is pulled out from between the pair of side covers 2e. The cover 2b covers the second sliding body 3B together with the base portion 2c at the storage position. The illustrated second sliding body 3B is disposed at the storage position in the space between the base portion 2c, the cover 2b, and the pair of side covers 2e, with the vehicle entry starting point side being pulled out from the storage position to the pull-out position. The illustrated cover 2b covers the vehicle entry starting point side of the second sliding body 3B at the storage position. The pair of side covers 2e also cover the vehicle entry starting point side of the second sliding body 3B in a sandwiched state at the storage position.

[0072] 14, the second sliding body 3B has a tip cover 3b at the tip on the vehicle entry starting point side. The tip cover 3b is provided with a cover main body 3b1 that covers the tip on the vehicle entry starting point side of the second sliding body 3B, and a pair of protruding parts 3b2 that protrude in the second direction W from both ends of the cover main body 3b1 in the second direction W and that cover from the outside the ends 2e1 on the vehicle entry starting point side of the pair of side covers 2e at the stored position.

[0073] The cover main body 3b1 covers the tip end of the second sliding body 3B on the vehicle entry starting point side from the first direction L and the third direction Z at the storage position. The protruding portion 3b2 covers the end 2e1 of the side cover 2e from the first direction L and from above at the storage position, and the end 2e1 of the side cover 2e receives the external load input to the cover main body 3b1 at the storage position. For example, in the vehicle charging device 1, when the vehicle 200 enters forward or backward from the vehicle entry starting point side, the wheel Ty may come into contact with the tip cover 3b from the vehicle entry starting point side due to the positional deviation of the vehicle 200, and then the wheel Ty may try to run up onto the cover 2b. Therefore, in this vehicle charging device 1, it is necessary to not only reduce the space for the wiring structure as described above, but also to have a load-bearing function that resists the external load from the wheel Ty when the wheel Ty comes into contact with or runs up, thereby improving durability. In this vehicle charging device 1, when the wheel Ty comes into contact with the front end cover 3b (e.g., the cover main body 3b1) in the storage position, the external load from the wheel is transmitted from the pair of protrusions 3b2 to the ends 2e1 of the pair of side covers 2e. In this vehicle charging device 1, the pair of side covers 2e are fixed to the base portion 2c, so that the external load from the wheel can be received by the ends 2e1 of the pair of side covers 2e. Therefore, the durability of this vehicle charging device 1 can be improved.

[0074] Here, in this vehicle charging device 1, by providing the above load-bearing structure (hereinafter referred to as the "first load-bearing structure") 300 between the base portion 2c and the cover 2b, the load-bearing function when the wheel Ty comes into contact with the end cover 3b in the storage position can be ensured by the two-point load-bearing structure (second load-bearing structure) 400 formed by the protrusion 3b2 of the end cover 3b, the end portion 2e1 of the side cover 2e, and the base portion 2c, and the load-bearing function when the wheel Ty goes over the end cover 3b and onto the cover 2b can be ensured by the first load-bearing structure 300.
