It is made into the box shape which has the turned rotation member 52 and the upper part opened. As will be described later, when the rotating member 52 is in a substantially horizontal state, the battery 46 can be placed on the rotating member 52. The main body member 51, the rotating member 52, and the hinge member 53 (excluding the shaft member 58) are formed of, for example, resin.

  Although not shown in the drawings, fixing portions for screwing the bracket 47 to the bracket 47 are appropriately formed on the outer surfaces of the side surface portions 51 b and 51 b of the battery tray device 50.

  Further, locking portions 51d and 51d for locking the fixing bracket 60 are formed on the upper portions of the center portions in the front-rear direction of the left and right side surface portions 51b and 51b, respectively.

  In addition, projecting pieces 51e, 51e, 51a, 51e formed on the upper part of the front end of the left and right side parts 51b, 51b and the upper part of the left and right ends of the turning member 52 so as to face each other when the turning member 52 is in the standing state 52e and 52e are provided, respectively, and iron pieces 54 and 54 are provided on the surface of the projecting piece portions 51e and 51e on the main body member 51 side on the side facing the projecting piece portions 52a and 52a of the rotating member 52. The magnet pieces 55, 55 are fixed to the surfaces of the protruding piece portions 52e, 52e on the rotating member 52 side which are fixed and face the protruding piece portions 51e, 51e of the main body member 51. When the rotating member 52 is set in the standing state, the rotating pieces 52 are held in the standing state by adsorbing the magnet pieces 55 and 55 and the iron pieces 54 and 54.

  As shown in FIG. 4, the hinge member 53 includes a first member 56 that is fixed to the lower surface of the mounting surface portion 51 a of the main body member 51, a second member 57 that is fixed to the rotating member 52, and a shaft support portion thereof. And a shaft member 58 inserted through the portions 56a and 57a. In this case, each of the first member 56 and the second member 57 has a substantially triangular shape when viewed in the axial direction, and when the rotating member 52 is rotated to the horizontal state, the one side portions 56b and 57b are in contact with each other. This prevents the turning member 52 from turning below the horizontal state, and when the battery 46 is temporarily placed on the turning member 52 as will be described later, the battery 46 The weight of can be supported. The first member 56 and the second member 57 may be fixed to the main body member 51 and the rotating member 52 with an adhesive or a screw.

  First, as shown in FIGS. 5 and 6, the rotating member 52 of the battery tray device 50 is placed in a horizontal state, and an enlarged placement area Y is formed adjacent to the front of the main placement area X. The rotating member 52 may be in a horizontal state in advance before this process.

  Next, as shown in FIG. 6, the battery 46 prepared on the work bench 73 provided in the mounting work area is held by the holding portion 84. The battery 46 is automatically supplied onto the work table 73.

  Next, as shown by an arrow α in FIG. 7, the arm 83 is rotated while being bent, so that the battery 46 is placed in both the loading regions X and Y of the battery tray device 50 as shown by a dashed line in FIG. 5. Is moved upward on the enlarged mounting area Y side. At this time, a gap S of a predetermined amount or more is provided in the front-rear direction between the rear end of the battery 46 and the front end P of the front window glass 17. Then, the battery 46 is moved downward as shown by an arrow β in FIGS. 5 and 7, and the battery 46 is placed on the mounting areas X and Y in an enlarged manner as shown by solid lines in FIGS. 8 and 5. Place it close to the region Y side. Then, after the gripping by the gripping part 84 is released, the arm 83 is moved upward so that, for example, the lower end of the gripping part 84 is positioned higher than the roof of the automobile 1.

  Next, as shown by an arrow γ, the battery 46 is slid in a substantially horizontal direction toward the main placement area X and placed on the main placement area X.

  Next, as shown by an arrow δ in FIGS. 9 and 5, the rotating member 52 is rotated to the upright state. Further, the battery 46 is fixed to the battery tray device 50 by the fixing bracket 60.

  As described above, according to the present embodiment, the battery tray device 50 is provided adjacent to the main placement area X where the battery 46 is placed, and the main placement area X, and the battery 46 as a whole. Is configured to be capable of forming an enlarged placement region Y that allows the battery 46 to be temporarily placed in a state of being located outward in plan view from a lower region of the member 22 (vehicle body constituting member) constituting the cowl 20. Therefore, after forming the enlarged placement area Y, the battery 46 is lowered from above the placement area Y side of the placement areas X and Y to enlarge the placement of both placement areas X and Y. The cowl upper panel 22 (vehicle body constituting member) constituting the cowl 20 is moved by moving the temporarily mounted battery 46 to the main mounting area X in a substantially horizontal direction. The battery 46 is disposed in the main mounting area X below Can. When placing the battery 46 on the battery tray device 50, it is possible to use the palletizer 80 (assembly device) that is placed by lowering the battery 46 from above. In addition, since the rotation member 52 (part) that forms the enlarged placement area Y can be stored after the battery 46 is placed on the main placement area X, the enlarged placement area Y can be stored. It is possible to place other articles such as the air cleaner 45 in the remaining space.

  In recent years, the front window glass 17 may be greatly inclined due to the design of the automobile. In this case, as described above, the front end position of the front window glass 17 moves forward. The front end must also be extended forward. In other words, when the battery 46 is disposed in the rear portion of the engine room 3 such as in the vicinity of the dash panel 11, if the front window glass 17 is largely inclined, the battery 46 is likely to be positioned below the cowl 20. In such a case, by using the battery tray device 50 according to the present embodiment, the battery 46 can be placed while using an assembly device such as the palletizer 80.

  Next, a modified example of the battery tray device 50 will be described. That is, as shown in FIG. 10, on the upper surface of the mounting surface portion 51a of the main body member 51 and the rear surface 52f of the rotating member 52 (the surface that becomes the upper surface in the horizontal state), the protrusions 51g, 51g, 52g and 52g may be provided respectively. By doing so, the sliding resistance when the battery 46 is slid in the substantially horizontal direction is reduced, and the battery 46 is slid and moved in the substantially horizontal direction in a state where the battery 46 is mounted on the mounting surface portion 51a and the rotating member 52.

The engaging protrusion 51h has an upward protruding portion 51k at the tip, and the rotating member 52 is held in an upright state by engaging the protruding portion 51k with the upper edge of the engaging hole 52h. In addition, when opening the rotation member 52 (it is set as a horizontal state), the engagement with the protrusion part 51k and the engagement hole 52h is cancelled | released by pushing down the front-end part of the engagement protrusion part 51h below. According to this structure, no iron piece or magnet piece is required, and the cost of the battery tray device can be reduced.

  Next, the second example will be described. As shown in FIG. 12, a hook-shaped portion engageable with the protruding piece portion 52a on the rotating member 52 side is provided at the tip of the protruding piece portion 51e on the main body member 51 side. 51m is provided, and when the hook-shaped portion 51m is engaged with the protruding piece 52a on the rotating member 52 side, the rotating member 52 is held in an upright state. In addition, when opening the rotation member 52 (it is set as a horizontal state), engagement is cancelled | released by opening the front-end | tip part (front-end part) of the hook-shaped part 51m to right and left as shown by arrow (sigma). According to this structure, as in the first example, an iron piece and a magnet piece are not required, and the cost of the battery tray device can be reduced.

  Next, a third example will be described. In this example, as shown in FIG. 13, neither the main body member 51 nor the rotating member 52 is provided with a protruding piece portion, and the side surface portion of the main body member 51. At the front end of 51b, a hook-shaped portion 51n that can be engaged with the side portion of the rotating member 52 is provided. Then, when the hook-shaped portion 51n is engaged with the side portion of the rotating member 52, the rotating member 52 is held in an upright state. In addition, when opening the rotation member 52 (it is set as a horizontal state), engagement is cancelled | released by opening the front-end | tip part (front-end part) of the hook-shaped part 51n to right and left like 2nd example. According to this structure, as in the first example, not only an iron piece and a magnet piece are unnecessary, but there is no need to provide a protruding piece portion, and in addition to the cost reduction of the battery tray device, the structure can be simplified.
