When formed, a gap corresponding to the thickness of the second support wall 48B can be secured between the side edge of the tray T placed on the tray receiver 36 and the left and right inner walls of the storage chamber 13. Therefore, even if a heating structure such as a heater is arranged in the inner wall on the side of the warming chamber 15, the tray T is reliably prevented from coming into contact with the inner wall and the tray T is softened by the heating structure. And deformation can be eliminated. Further, since the tray T can be smoothly inserted and removed while being guided by the continuous second support wall 48B, the second support wall 48B can function as a guide member for the tray T. The structure can be simplified as compared with the case where a separate guide member is provided, and the width direction of the storage chamber 13 can be greatly used because a space for providing the guide member is not necessary. Further, when the support wall 48 is attached to and detached from the unit support 58, the first support wall 48A can be inserted and connected while sliding on the step portion 60 of the first support 58A, or can be separated. The attaching / detaching operation can be easily performed.

  If the positioning structure is configured by the step portion 60 of the first support tool 58A and the notch portion 64 formed in the front and rear of the first support wall 48A, the notch portion 64 is supported only by dropping into the step portion 60 and engaging. The wall 48 can be positioned forward and backward, and the partition unit U can be properly supported in the forward and backward positioning state. Further, since the positioning is performed using the step portion 60 of the first support tool 58A, the positioning structure can be formed only by forming the notch 64 in the first support wall 48A. Therefore, the connecting and fixing structure of the partition unit U with respect to the inner wall of the storage chamber 13 can be simplified, and the manufacturing cost of the trolley can be reduced.

Next, the support wall 48 is inserted into the rear unit support 58 in the same manner as described above, and the support wall 48 is supported by the step portion 60 of the first support 58A. Finally, the partition unit U can be supported and fixed in the storage chamber 13 by dropping and engaging the four notches 64 in the front and rear, right and left with the stepped portion 60 of the first support 58A. By sequentially fixing the partition units U from the upper side or the lower side and fixing all the partition units U, the interior of the storage room 13 is divided into a cold storage room 14 and a warm room 15.

  FIG. 10 shows another embodiment of the method for attaching the unit support 58. There, slits 66 are formed in the vertical column 7A and the middle column 29 of the housing frame 7, and the support pieces 60 of the first support member 58A and the second support member 58B are inserted into the slit 66 so that the fastening seat 59 is the vertical column. The rivet 62 was fastened and fixed while being positioned on the inner surface side of 7A or the middle pillar 29. As described above, when the first support tool 58A and the second support tool 58 are fixed with the support piece 60 inserted into the slit 66, the first support tool 58A and the second support tool 58B rotate around the rivet 62. Since it can be regulated by the slit 66, the posture of the first support tool 58A and the second support tool 58B is not changed, and can be securely fixed to the vertical column 7A or the middle column 29. Since others are the same as the previous embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted.

  As described above, in the tray support 58 of the layout vehicle according to the present embodiment, the support walls 48 of the left and right tray receivers 36 are inserted and connected to both the first and second supports 58A and 58B. The partition unit U can be connected and fixed to the inner wall of the storage chamber 13, and the support wall 48 of the tray receiver 36 in the connected state is clamped so as not to be laterally movable by either the first support tool 58A or the second support tool 58B. Then, the positioning structure is used for positioning in the front-rear direction. According to such a tray support 58, the front and rear direction (insertion direction) and the left and right direction (difference) of the tray receiver 36 can be achieved by a one-touch operation of simply inserting the support walls 48 of the left and right tray receivers 36 into the unit support 58. It is possible to reliably connect the inner wall of the storage chamber 13 with the unit support member 58 in a state where there is no room to move the partition unit U by preventing the movement in the direction perpendicular to the insertion direction. Accordingly, the partition unit U can be accurately positioned and fixed with respect to the inner wall of the storage chamber 13, and the partition unit U can always be supported at an appropriate position.

  A lower end and an upper end of the first support wall 48A and the second support wall 48B extending from the tip of the tray receiving body 46 are respectively connected to the first support 58A and the second support 58B, and the vertical column of the housing frame 7. 7A and the middle pillar 29 were sandwiched. As described above, when the upper and lower end portions of the support wall 48 are clamped and fixed using the left and right inner walls of the storage chamber 13 which is the reference for arranging the partition unit U, the partition unit U with respect to the inner wall of the storage chamber 13 is fixed. Positioning and fixing can be performed more accurately, and the partition unit U can always be supported in a stable state at an appropriate position. Further, since the support wall 48 is sandwiched by both the first support tool 58A and the second support tool 58B, it is possible to more reliably prevent the support wall 48 from moving in the left-right direction.

  The opposing distance W (see FIG. 5) between the upper and lower tray receiving bodies 46 of the arrangement vehicle is sufficient to prevent the tray receiving body 46 from coming into contact with the tableware in addition to the height of the tableware placed on the tray T. It is set including a margin. As in this embodiment, by preventing the partition unit U from floating and always supporting the partition unit U at an appropriate position, the margin clearance can be reduced, and the overall height of the trolley can be kept low. Can do.

  The first support tool 58A and the second support tool 58B are fastened and fixed to the left and right inner walls of the storage chamber 13 with the holding portions 61 facing each other vertically. Since the facing interval between the step portions 60 is set to be slightly larger than the vertical width of the support wall 48, the support wall 48 is positioned between the step portions 60 of the first support tool 58A and the second support tool 58B. By inserting in a combined state, the upper and lower and left and right sides of the support wall 48 are smoothly guided while being guided by the upper and lower step portions 60 and 60, the respective holding portions 61, and the vertical columns 7A and the middle columns 29 of the housing frame 7. Can be plugged in. Further, since the first support tool 58A and the second support tool 58B are composed of the same crank-shaped member including the fastening seat 59, the stepped portion 60, and the clamping portion 61, the number of parts of the unit support tool 58 is reduced. Thus, it is possible to reduce the manufacturing cost of the distribution vehicle. When assembling the unit support 58, it is not necessary to identify the first support 58A and the second support 58B. Therefore, the assembly work is saved and the first support 58A and the second support 58B are turned upside down. It is possible to eliminate assembly mistakes for fastening and fixing.

  The dimension in the front-rear direction of the tray receiving body 46 is set slightly smaller than that of the storage chamber 13, and the first support wall 48 </ b> A and the second support wall 48 </ b> B are continuously formed along the left and right side edges of the tray receiving body 46. Since it is formed, a gap corresponding to the thickness of the second support wall 48B can be ensured between the side edge of the tray T placed on the tray receiver 36 and the left and right inner walls of the storage chamber 13. Therefore, even when the panel heater 33 is disposed inside the left panel 10 and the right panel 11, it is possible to reliably prevent the tray T from coming into contact with the inner wall of the front and the tray T due to the heat of the panel heater 33. Softening and deformation can be eliminated. Further, since the tray T can be smoothly inserted and removed while being guided by the continuous second support wall 48B, the second support wall 48B can function as a guide member for the tray T. The structure can be simplified as compared with the case where a separate guide member is provided, and the width direction of the storage chamber 13 can be greatly used because a space for providing the guide member is not necessary. Further, when the support wall 48 is attached to and detached from the unit support 58, the first support wall 48A can be inserted and connected while sliding on the step portion 60 of the first support 58A, or can be separated. The attaching / detaching operation can be easily performed.

  Since the positioning structure is configured by the step portion 60 of the first support tool 58A and the notch portion 64 formed in the front and rear of the first support wall 48A, the notch portion 64 is simply dropped into the step portion 60 and engaged. It is possible to properly support the partition wall U in a state where the support wall 48 is positioned forward and backward and the partition unit U is positioned forward and backward. Further, since the positioning is performed using the step portion 60 of the first support tool 58A, the positioning structure can be formed only by forming the notch 64 in the first support wall 48A. Therefore, the connecting and fixing structure of the partition unit U with respect to the inner wall of the storage chamber 13 can be simplified, and the manufacturing cost of the trolley can be reduced.

  FIG. 9 shows a modification of the unit support 58. In FIG. 9, the vertical dimension of the fastening seat 59 of the previous embodiment is increased, and the step portion 60 is formed in the middle portion of the fastening seat 59. The facing distance between the fastening seat 59 and the clamping part 61 is set to be substantially the same as the thickness dimension of the first and second support walls 48A and 48B. In a state where the support wall 48 is connected to the unit support 58, the notch portion 64 of the support wall 48 falls into the stepped portion 60 and engages, and the lower end surface of the first support wall 48A of each notch portion 64 portion is the first. The first and second support walls 48A and 48B are clamped between the fastening seats 59 and the clamping portions 61 of the first and second support tools 58A and 58B. Since the other points are the same as in the previous embodiment, the same reference numerals are assigned to the same members, and the description thereof is omitted. As described above, when the first and second support walls 48A and 48B are sandwiched between the fastening seat 59 and the sandwiching portion 61, the support wall 48 is supported and fixed in a state of facing the left and right inner wall surfaces of the storage chamber 13 through the gap. it can. Accordingly, the tray T is moved away from the wall surfaces of the left panel 10 and the right panel 11 by the amount of the previous gap, and the heat of the panel heater 33 is further prevented from being transmitted to the tray T, and the tray T is softened and deformed. Can be solved more effectively. Further, when the partition unit U is attached and detached, the support wall 48 does not come into contact with the far-infrared radiation paint applied to the left and right panels 10 and 11, and the paint can be prevented from peeling off.

In the above embodiment, the partition body 35 and the pair of tray receivers 36 are connected by the connection projection 52 and the slide groove 53. However, the abutment wall 47 is fastened and fixed to the base frame 38 with screws or rivets. 35 and a pair of tray receivers 36 can be connected . The dimensions of the left-right direction (width direction) of the coercive cold chamber 14 is made smaller than that of the heat insulating chamber 15, may be reversed relationship or may be the same. If the left and right dimensions of the cold room 14 and the warm room 15 are the same, the tray receivers 36A and 36B can be made of the same member. The positioning structure may be an uneven engagement structure or a claw engagement structure provided on the support wall 48 and the inner wall surface of the storage chamber 13 or the unit support 58. The unit support 58 is provided by fastening and fixing the first support 58A and the second support 58B with the rivet 62, but the vertical column 7A and the middle column 29 are cut and raised by a press to support the unit. The tool 58 can be formed integrally with the vertical column 7A and the middle column 29.
