The lever 89 supports the current collector 86 from below so that the current collector 86 does not rotate further downward after contacting the lever 89. A base end portion 89 a of the lever 89 is rotatably supported by the slider 84. On the other hand, a lever biasing spring 891 that is a tension spring is bridged between the tip 89b of the lever 89 and the slider 84. In the above configuration, when not connected, the current collector 86 is supported by the lever 89 from below so that the current collector 86 does not rotate downward due to its own weight, and the contact surface 861 is in an orientation suitable for connection. Is held. On the other hand, at the time of connection, when the contact 73 comes into contact with the contact surface 861 of the current collector 86 and a downward force is applied to the current collector 86, the current collector 86 rotates downward against the biasing force of the lever biasing spring 891. Can move.

  The end of the support shaft 881 that is not connected to the current collector 86 is inserted into a spring case 883 attached to the slider 84. In the spring case 883, a lever urging spring 884 is provided between the other end of the support shaft 881 and the back of the spring case 883. The support shaft 881 can move from the spring case 883 in the advancing and retracting direction, and is urged by the lever urging spring 884 in the advancing direction from the spring case 883. In this manner, the current collector 86 is held so as to be individually movable in the forward / backward direction with respect to the current collector holder 85. In this embodiment, the individual current collectors 86 are configured to move individually in the direction of advancement / retraction to / from the current collection holder 85, but a plurality of current collectors 86 advance / retreat to the current collection holder 85 integrally. It can also be configured to move in the direction. In the present embodiment, the contact surfaces 861 of the plurality of current collectors 86 can be individually tilted, but the contact surfaces 861 of the plurality of current collectors 86 can also be configured to tilt integrally.

  The two guides 87 and 87 are arranged substantially in parallel so as to sandwich the current collector holder 85 and the plurality of current collectors 86 held by the current collector holder 85 from both sides in the second direction Y. In other words, the two guides 87 and 87 are disposed on both sides of the current collecting holder 85 in the second direction Y. The guide 87 is a plate-like member whose base is cantilevered by the slider 84, and protrudes from the slider 84 in the first direction X to the charging pallet 20 side than the plurality of current collectors 86. In particular, as shown in detail in FIG. 9, the guides 74 and 74, which are the guide portions 92a of the guide mechanism 92, are the guided portions 92b in the positions in the second direction Y of the two guides 87 and 87 on the slider 84. It is determined so as to be able to enter the first direction X while being in contact between the guides 87 and 87. Then, the distal ends of the guides 87 and 87 are such that the distance between the two guides 87 and 87 in the second direction Y gradually increases toward the distal ends, that is, the tip ends of the guides 87 and 87 become wider. The part is inclined in the second direction Y. Due to the shape of the guides 87 and 87 provided on the shelf side contact assembly 61 side, the two guides 74 and 74 as the guide portion 92a are received between the two guides 87 and 87 as the guided portion 92b. In addition, the force in the first direction X applied from the guide 74 of the guide portion 92a to the guide 87 of the guided portion 92b can be converted into a force in the second direction Y.

  The shelf-side contact assembly 61 is capable of displacing the first moving mechanism 101 that can displace the position and posture in the first direction X and the vertical direction with respect to the parking shelf 11 and the position in the second direction Y with respect to the parking shelf 11. The second moving mechanism 102 is attached to the parking shelf 11 side. In the above description, the attitude of the shelf-side contact assembly 61 refers to the direction of the current collector 86 that is the contact of the shelf-side contact assembly 61, and specifically refers to the direction of the contact surface 861 of the current collector 86. Next, the first moving mechanism 101 and the second moving mechanism 102 will be described.

[First moving mechanism 101]
The first moving mechanism 101 includes a base 81 fixed to a beam or the like of the parking tower 2, two parallel arms 82 and 82 supported by the base 81, and two bridges bridged between the arms 82 and 82. It comprises parallel slide shafts 83 and 83, arm urging mechanisms 91 and 91, and the like. 11 is a cross-sectional view taken along the line XI-XI in FIG. 7 for explaining the first moving mechanism.

  As shown in FIGS. 7, 8, and 11, the base 81 is mounted on the substrate 812 fixed to the beam of the parking tower 2, the two support portions 811 and 811 fixed on the substrate 812, and the substrate 812. The spring receiving portion 813 is provided upright. A base end portion of the arm 82 is rotatably supported on each support portion 811 by an arm rotation shaft 821 in the second direction Y. Thereby, the arms 82 and 82 can rotate in the first direction X. Two slide shafts 83, 83 are stretched in parallel on the distal end side of the two parallel arms 82, 82. By the slide shafts 83, 83, the two arms 82, 82 are coupled so as to rotate in the first direction X in synchronization. The slide shafts 83 and 83 are inserted through bearing portions 842 and 842 of the slider 84 to which the shelf side contact assembly 61 is fixed. As described above, the arms 82, 82 supporting the shelf-side contact assembly 61 rotate in the first direction X around the arm rotation shafts 821, 821, so that the shelf-side contact assembly 61 is in the first position relative to the parking shelf 11. The position and posture in the direction X and the vertical direction can be changed.

  The tip end sides of the arms 82 and 82 are urged toward the pallet in the first direction X by the arm urging mechanisms 91 and 91 (direction toward the charging pallet 20 side). As shown in particular detail in FIG. 11, each arm urging mechanism 91 includes an arm urging spring 911, a headed bolt 912, an urging force adjusting nut 914, washers 917, 918, and the like. Through the head bolt 912, a washer 917, an arm biasing spring 911, a washer 918, a spring receiving portion 813 of the base 81, a spring shaft support portion 913 of the arm 82, and a biasing force adjusting nut 914 are passed in this order. The tip end portion of the headed bolt 912 is supported by the spring shaft support portion 913 of the arm 82 so as to be rotatable in the first direction X. The compression of the arm biasing spring 911 can be changed by tightening or loosening the biasing force adjusting nut 914 that is screwed onto the tip of the head bolt 912, whereby the arm 82 by the arm biasing spring 911 is changed. The urging force can be adjusted. In the arm urging mechanism 91 configured as described above, when the distal end side of the arm 82 rotates in the first direction X in the direction opposite to the pallet (the direction toward the opposite side of the charging pallet 20), the head of the headed bolt 912 and the spring support The arm biasing spring 911 contracts with the portion 813, and the arm 82 is biased toward the pallet by the elastic recovery force of the contracted arm biasing spring 911. The arm biasing spring 911 is assembled so as to be contracted when not connected (a state where the contact 73 and the current collector 86 are not in contact). In this way, the distal end side of the arm 82 is always urged toward the pallet in the first direction X.

  The pivot position when the arm 82 is not connected includes the biasing force of the arm biasing spring 911, the arm position adjusting bolt 915 screwed to the spring receiving portion 813 of the base 81, and a stopper provided on the arm 82. 822. When not connected, the tip of the arm position adjusting bolt 915 is in contact with the stopper 822. In this way, the stopper 822 contacts the arm position adjusting bolt 915, so that the tip end side of the arm 82 is restricted from rotating further in the first direction X toward the pallet, and the rotation when the arm 82 is not connected. The moving position is determined.

[Second moving mechanism 102]
The second moving mechanism 102 includes two slide shafts 83 and 83, a slider 84 that can slide along the slide shafts 83 and 83, two slider biasing springs 93 and 93, and the like.

  The axial direction of the slide shafts 83 and 83 is substantially parallel to the second direction Y. The slide shafts 83 are inserted through a slider 84 to which the shelf side contact assembly 61 is fixed. The slider 84 includes a substrate 841 and two bearing portions 842 and 842 fixed to the substrate 841. A current collecting holder 85 and guides 87 and 87 of the shelf side contact assembly 61 are attached to the substrate 841 of the slider 84. Further, the two bearing portions 842 and 842 of the slider 84 are disposed on both sides in the second direction Y with respect to the current collector holder 85, and two slide shafts 83 and 83 are inserted into each bearing portion 842. ing.

  The two slider urging springs 93 and 93 are inserted through one slide shaft 83. One slider biasing spring 93 is positioned between one arm 82 and the bearing portion 842 of the slider 84, and the other slider biasing spring 93 is positioned between the other arm 82 and the bearing portion 842 of the slider 84. doing.

  In the second moving mechanism 102 configured as described above, the slider 84 can move in the second direction Y along the slide shafts 83, 83, and the shelf-side contact assembly 61 moves relative to the parking shelf 11 by such movement of the slider 84. The position in the second direction Y can be displaced. Then, the slider 84 moved along the slide shafts 83 and 83 by the slider biasing springs 93 and 93 is a reference position on the slide shafts 83 and 83 (in this embodiment, the second of the slide shaft 83 is the second). It is urged to return to the approximate center of the direction Y). In this way, the slider 84 is held at a reference position in the second direction Y when not connected.

  Here, in the power supply system 60 configured as described above, the plurality of current collectors 86 of the shelf-side contact assembly 61 and the plurality of contacts of the pallet-side contact assembly 62 during the operation of moving the charging pallet to a predetermined parking position of the parking shelf. A mechanism in which the current collector 73 is aligned and the current collector 86 and the contact 73 are electrically connected will be described.

  The wheel 24 of the charging pallet 20 is transferred to the shelf rail 17 of the parking shelf 11, and the charging pallet 20 moves to the parking shelf 11 in the first direction X along the shelf rail 17 to the predetermined parking position. On the other hand, when the charging pallet 20 is displaced in the second direction Y, as shown in FIGS. 3 and 9, a pair of guided portions 92b of the guide mechanism 92 provided on the shelf-side contact assembly 61 side. A pair of guides 74 and 74 which are guide portions 92 a of the guide mechanism 92 provided on the pallet side contact assembly 62 side come into contact with each other, and the guides 74 and 74 enter between the guides 87 and 87. Further, when the charging pallet 20 continues to traverse in the first direction X, the force of the guided portion 92b is caused by the force in the first direction X applied from the guides 74, 74 of the guiding portion 92a to the guides 87, 87 of the guided portion 92b. The guides 87 and 87 are pressed in the second direction Y. Due to the engagement between the guides 87 and 87 and the guides 74 and 74, the slider 84 on which the shelf-side contact assembly 61 and the guides 87 and 87 are fixed moves in the second direction Y along the slide shafts 83 and 83. Thus, the current collector 86 of the shelf-side contact assembly 61 and the contact 73 of the pallet-side contact assembly 62 are appropriately positioned in the second direction Y so that each contact 73 and the current collector 86 corresponding thereto correspond to each other. The

  In the state where the shelf side contact assembly 61 and the pallet side contact assembly 62 are positioned in the second direction Y as described above, the charging pallet 20 continues to traverse in the first direction X and reaches a predetermined parking position. In this process, as shown in FIG. 4, each contact 73 and the corresponding current collector 86 come into contact with each other, and eventually, the plurality of contacts 73 of the pallet-side contact assembly 62 cause a plurality of contacts on the shelf-side contact assembly 61. The current collector 86 is pressed. By this pressing force, the arms 82 and 82 supporting the shelf side contact assembly 61 are rotated in the first direction X in the direction opposite to the pallet. After the contact 73 and the current collector 86 come into contact with each other during the operation of moving the charging pallet 20 to the predetermined parking position of the parking rack 11, the arms 82 and 82 are rotated in the first direction X in the direction opposite to the pallet. Therefore, the arms 82 and 82 are biased by the arm biasing mechanisms 91 and 91 in such a direction as to press the current collector 86 against the contact 73. In this manner, the contact 73 and the current collector 86 that have been in contact with each other during the operation of moving the charging pallet 20 to the predetermined parking position of the parking rack 11 are kept in pressure contact. Further, during the movement of the charging pallet 20 to the predetermined parking position of the parking rack 11, the current collector 86 tilts following the inclination of the contact 73 according to the pressing force received from the contact 73 that is in contact. Or move in the forward / backward direction with respect to the contact holder 72. As described above, when the charging pallet 20 reaches a predetermined parking position, the current collector 86 and the contact 73 are in contact with each other with an appropriate contact pressure without causing a single contact, resulting in poor contact. Electrically connected without any problems.

  When the current collector 86 of the shelf-side contact assembly 61 and the contact 73 of the pallet-side contact assembly 62 are electrically connected as described above, the power supply system 60 can charge the electric vehicle EV. FIG. 12 is a connection diagram of the charging pallet and the charging power supply device. As shown in the figure, among the five current collectors 86 provided in the shelf side contact assembly 61, the current collector 86 at the center position is connected to the neutral line, and the other four current collectors 86 are Two of them are connected to the R-phase voltage line, and the other two current collectors 86 are connected to the T-phase voltage line. The R-phase voltage line and the T-phase voltage line are connected to the switch 43 of each parking shelf 11 provided in the charging power supply device 42. The switch 43 is connected to an AC power source 44. At the connection portion between the current collector 86 and the contact 73, the R phase and the T phase are branched into two paths. As a result, the value of the current flowing through each contact 73 is reduced, and the temperature rise at the connecting portion between the current collector 86 and the contact 73 is suppressed.

  The relay cable 31 is led from the pallet side contact assembly 62 provided on the charging pallet 20 to the cable storage box 30. In the cable storage box 30, the connector 35 of the charging cable 34 is connected to the connector 32 provided at the tip of the relay cable 31. And the charge adapter 36 provided in the front-end | tip of this charge cable 34 is connected to the charge port 51 (refer FIG. 2) of the electric vehicle EV. The electricity sent to the charging port 51 in this way is sent to the battery 53 via the A / D circuit 52 and charged to the battery 53. The charging status of the battery 53 is managed by an electronic control unit 54 (ECU).

  The charging pallet 20 is provided with two pallet side contact assemblies 62, and one pallet side contact assembly 62 is connected to the other pallet side contact assembly 62 by a connection cable 45. A cable storage box 30 is provided at a position adjacent to each pallet side contact assembly 62, and the relay cable 31 in one of the cable storage boxes 30 is used according to the position of the charging port 51 of the electric vehicle EV. Can be charged. In the present embodiment, two cable storage boxes 30 are diagonally arranged on the charging pallet 20, but four cable storage boxes 30 are provided on the front and rear, left and right of the charging pallet 20, or two are charged. The pallet 20 may be provided on one side of the pallet 20 or one may be provided at an appropriate position on the charging pallet 20.

  In the elevator type parking apparatus 1 described above, the charging pallet 20 is stored in the parking shelf 11 corresponding to charging, and the plurality of contacts 73 of the pallet side contact assembly 62 on the charging pallet 20 side and the parking shelf 11 are stored. It is possible to perform reliable positioning and electrical connection with the plurality of current collectors 86 of the side shelf side contact assembly 61. Then, at the final stage where the charging pallet 20 is transferred to the parking rack 11 and traverses in the first direction X to the predetermined parking position, a displacement (error) of the parking rack 11 relative to the predetermined parking position occurs in the charging pallet 20. Even if it is, the plurality of current collectors 86 may integrally change the position in the first direction X and the second direction Y with respect to the parking shelf 11 as the shelf side contact assembly 61, or the current collector 86 may be the current collector holder. The position error of the charging pallet 20 is absorbed by the individual movement in the direction of advancing and retreating with respect to 85, or the contact surface 861 of the current collector 86 being individually tilted, and the pallet side contact assembly 62 and the shelf The side contact assembly 61 is properly positioned.

  For example, when the charging pallet 20 is shifted in the first direction X with respect to a predetermined parking position of the parking shelf 11, the pallet side is moved during the operation of moving the charging pallet 20 to the predetermined parking position of the parking shelf 11. When the shelf-side contact assembly 61 is pressed against the contact assembly 62 and the arms 82 and 82 are rotated, the position of the collector 86 of the shelf-side contact assembly 61 in the first direction X with respect to the parking shelf 11 is changed. Thus, the displacement in the first direction X with respect to the predetermined parking position of the parking shelf 11 of the charging pallet 20 is absorbed. In this way, the plurality of current collectors 86 of the shelf side contact assembly 61 and the plurality of contacts 73 of the pallet side contact assembly 62 can be appropriately positioned in the first direction X. Even when the charging pallet 20 is displaced in the vertical direction with respect to the predetermined parking position of the parking shelf 11, the rotation of the arms 82 and 82 in the same manner as described above causes the shelf side contact assembly 61 to move relative to the parking shelf 11. By changing the position and posture in the vertical direction, the plurality of current collectors 86 of the shelf side contact assembly 61 and the plurality of contacts 73 of the pallet side contact assembly 62 can be appropriately positioned in the vertical direction. In this case, in addition, since there is an allowable range in the longitudinal direction (substantially up and down direction) of the contact area between the contact 73 and the current collector 86, the contact 73 and the current collector 86 can be appropriately contacted at an appropriate position. .

  Further, for example, when the charging pallet 20 is shifted in the second direction Y with respect to the predetermined parking position of the parking shelf 11, during the operation of moving the charging pallet 20 to the predetermined parking position of the parking shelf 11, The guides 87 and 87 on the shelf side contact assembly 61 side are guided by the guides 74 and 74 on the pallet side contact assembly 62 side, and the slider 84 moves integrally with the shelf side contact assembly 61 in the second direction Y. . Thereby, the position of the collector 86 of the shelf side contact assembly 61 in the second direction Y with respect to the parking shelf 11 is changed, and the positional deviation in the second direction Y with respect to the predetermined parking position of the parking shelf 11 of the charging pallet 20 is changed. Absorbed. In this manner, the plurality of current collectors 86 of the shelf side contact assembly 61 and the plurality of contacts 73 of the pallet side contact assembly 62 can be appropriately positioned in the second direction Y.

  As described above, when the shelf-side contact assembly 61 is rotationally displaced so as to absorb the positional deviation in the vertical direction and the first direction X with respect to the predetermined parking position of the parking shelf 11 of the charging pallet 20, The posture (orientation) of the current collecting holder 85 changes with the change in the position in the one direction X and the vertical direction. In contrast, in the present embodiment, the contact surface 861 of the current collector 86 can be tilted by the holding mechanism 88 of the current collector 86, and the current collector 86 is directed toward the contact 73 by the holding mechanism 88 and the first moving mechanism 101. The contact point 861 of the contact 73 and the current collector 86 is changed to a surface by changing the posture of the current collector 86 (the direction of the contact surface 861) even if the posture of the current collector holder 85 is changed. It is possible to maintain the state of being hit by. In this manner, after the charging pallet 20 is moved to the predetermined parking position of the parking shelf 11 and moved, the contact 73 and the contact surface 861 of the current collector 86 are maintained in a state where the surfaces are in pressure contact with each other. . Further, even if individual differences or wear occur in the specific contact 73 or the current collector 86, the current collector 86 or the specific current collector 86 in contact with the specific contact 73 moves up and down by the pressing force received from the contact 73. By tilting or moving in the direction of advancement / retraction to the current collector holder 85, they can make good contact. Therefore, all the corresponding contacts 73 and the current collector 86 are stably and electrically connected without causing contact failure such as contact with each other or separation due to vibration or the like.

  Moreover, in the elevator type parking apparatus 1 demonstrated above, the pallet side contact assembly 62 is comprised comparatively compactly. In particular, the size of the pallet side contact assembly 62 in the second direction Y is determined by the plurality of contacts 73 and the two guides 74 and 74. An engaging groove 28 of the engaging roller 27 is provided at the side end 21 of the charging pallet 20 where the pallet side contact assembly 62 is disposed. In order to sufficiently secure the size of the engagement groove 28, it is preferable that the pallet side contact assembly 62 is configured compactly as in the present embodiment. Further, as in this embodiment, the pallet-side contact assembly 62 can be disposed at the side end 21 of the charging pallet 20, so that the arrangement space of the charging pallet 20 itself is made the same as that of the standard pallet 90. be able to. For example, when the pallet-side contact assembly 62 is disposed on the lower surface of the charging pallet 20, the pallet-side contact assembly 62 protrudes into the passenger compartment immediately below the parking shelf 11 that stores the charging pallet 20, so that the shelf pitch is increased. The disadvantage of having to do so arises.

  Furthermore, in the elevator type parking apparatus 1 described above, the first moving mechanism 101 is provided for the movement of the shelf-side contact assembly 61 in the first direction X, and the shelf-side contact assembly 61 is moved in the second direction Y. A second moving mechanism 102 is provided for the movement of the second movement mechanism. In this way, the moving mechanism is separated for each operation direction. Therefore, it is easy to individually optimize the urging force, the moving range, and the like with the first moving mechanism 101 and the second moving mechanism 102, and each moving mechanism can be operated reliably.

  In the above embodiment, the first moving mechanism 101 and the second moving mechanism 102 are provided on the shelf-side contact assembly 61 side, and the position and posture of the shelf-side contact assembly 61 with respect to the parking shelf 11 are changed. However, other embodiments can be employed. For example, the first moving mechanism 101 and the second moving mechanism 102 are provided on the pallet side contact assembly 62 side, and the position and posture of the pallet side contact assembly 62 with respect to the charging pallet 20 can be changed. Further, for example, the first moving mechanism 101 can be provided on one of the shelf side contact assembly 61 side and the pallet side contact assembly 62 side, and the second moving mechanism 102 can be provided on the other side. In these examples, one of the shelf side contact assembly 61 and the pallet side contact assembly 62 provided with the second moving mechanism 102 is provided with the guided portion 92b of the guide mechanism 92, and the other provided with the guide portion of the guide mechanism 92. 92a is provided.

  Moreover, in the said embodiment, although demonstrated as an example the elevator parking apparatus 1 of a lower 90 degree entrance system as a mechanical parking apparatus, as long as it is a system which stores the charging pallet 20 in a fixed position for a fixed time, what kind A mechanical parking device of a system may be used, and for example, it can be applied to various mechanical parking devices such as a plane reciprocating type, a vertical / horizontal puzzle moving type, and a multistage type. Moreover, in the elevator type parking apparatus 1 of the said embodiment, although the example which mixedly mounted the charging pallet 20 for electric vehicles EV and the general standard pallet 90 without a charging accessory was shown, all are mounted with electric vehicles EV. The charging pallet 20 may be used.

  Further, in the above embodiment, the shelf side contact assembly 61 is diagonally arranged on the elevator parking device 1 and the pallet side contact assembly 62 is diagonally arranged on the charging pallet 20. -It is applicable to various combination arrangements depending on whether the parking rack 11 used for charging is one side or both sides, etc. For example, one set of the shelf side contact assembly 61 may be provided for each parking shelf 11 corresponding to charging. Moreover, the pallet side contact assembly 62 may be one place on one side as long as the charging pallet 20 is always stored in the same direction.

  In the above embodiment, the guides 87 and 87 on the shelf side contact assembly 61 side protrude toward the pallet in the first direction X from the current collector 86, and the guides 74 and 74 on the pallet side contact assembly 62 side are the contacts 73. When the charging pallet 20 is moved to a predetermined parking position on the parking rack 11, the guide 87 and the guide 74 are moved more than the contact 73 and the current collector 86. Touch first. However, it is only necessary that the guide 87 and the guide 74 come in contact before the contact 73 and the current collector 86, and the guides 87 and 74 are not necessarily protruded in the first direction X from the contact 73 or the current collector 86. It is not limited. When the contact 73 and the current collector 86 are not connected, the distance in the first direction X between the guides 74 and 74 on the pallet side contact assembly 62 side and the guides 87 and 87 on the shelf side contact assembly 61 side is If the distance of the contact 73 is shorter than the distance in the first direction X, the guide 87 and the guide 74 come into contact before the contact 73 and the current collector 86. For example, even if the current collector 86 protrudes toward the charging pallet 20 from the guides 87 and 87 in the shelf side contact assembly 61, the guide 74 on the pallet side contact assembly 62 side and the guide on the shelf side contact assembly 61 side. The guide 74 of the pallet side contact assembly 62 protrudes more toward the shelf side contact assembly 61 so that the separation distance of the first direction X of 87 becomes shorter than the separation distance of the current collector 86 and the contact 73. That's fine. The reverse is also true, even if the contact 73 in the pallet side contact assembly 62 protrudes from the guides 74 and 74 toward the shelf side contact assembly 61, the guide 74 on the pallet side contact assembly 62 side and the shelf side. The guide 87 on the shelf side contact assembly 61 side is moved to the pallet side contact assembly 62 so that the distance in the first direction X of the guide 87 on the contact assembly 61 side is shorter than the distance between the current collector 86 and the contact 73. It only needs to protrude larger toward the.

  Further, in the above embodiment, the guides 87 and 87 on the shelf side contact assembly 61 side are arranged so as to sandwich the guides 74 and 74 on the pallet side contact assembly 62 side from both sides in the second direction Y. However, the reverse is also possible.

  In the above embodiment, the guides 87, 87 on the shelf side contact assembly 61 side are arranged on both sides in the second direction Y of the plurality of current collectors 86, and the guides 74, 74 on the pallet side contact assembly 62 side are Although arrange | positioned at the both sides of the 2nd direction Y of the some contact 73, arrangement | positioning of the guides 87 and 74 is not limited to this. For example, the guides 87 on the shelf side contact assembly 61 side are arranged side by side in the second direction Y above or below the plurality of current collectors 86, and the guides on the pallet side contact assembly 62 side are corresponding to this. 74 and 74 may be arranged side by side in the second direction Y above or below the plurality of contacts 73.

  Further, the gaps in the second direction Y of the ends of the guides 87 on the shelf side contact assembly 61 side facing the pallet side contact assembly 62 are widened in the second direction Y, and the guides on the pallet side contact assembly 62 side are widened. The intervals in the second direction Y of the end portions (guide surfaces 741, 741) facing the shelf-side contact assembly 61 of 74, 74 are tapered, but the shape is not limited to this.
