  As shown in FIG. 7, the right side reinforcing member 40A and the left side reinforcing member 40B are arranged inside the opening 27, but are not cured between the right side reinforcing member 40A and the left side reinforcing member 40B. There is enough space for the insulation to flow.

  In the heat insulation unit 2, the machine room 3a that houses the machine room unit 3 includes the upper surface of the mounting table 23 (the upper surface 23A1 of the front cover 23A), the lower surface of the second heat insulation box 22 (the bottom surface 22A1 of the second outer box 22A), and The first heat insulating box 21 is constituted by the first standing wall 21A1. In addition to the machine room unit 3, other machines may be accommodated in the machine room 3a. About 3/4 of the upper surface of the mounting table 23 is a part where the machine room unit 3 is arranged, and the remaining part includes other machinery, the second heat insulating box 22 and the mounting table 23. A fixed column 29 or the like that supports the second heat insulating box 22 is installed.

  The machine room unit 3 includes a refrigeration unit 31 constituting a refrigeration cycle for cooling the refrigerator compartment 22a, a plate-like bottom portion 32 to which the refrigeration unit 31 is attached, and a support portion 33 standing on the bottom portion 32. Yes. The refrigeration cycle is a known cooling system that includes a compressor, a condenser, a capillary tube, an evaporator, an expansion valve, and the like, and uses the heat of vaporization of the refrigerant circulating through them. The machine room unit 3 includes components other than the evaporator among a group of components (compressor and the like) constituting the refrigeration cycle. In this specification, a component group of the refrigeration cycle provided in the machine room unit 3 is referred to as a refrigeration unit 31.

  The bottom 32 is a plate-like member having a rectangular shape in plan view, and is composed of a metal plate or the like. Each component constituting the refrigeration unit 31 is attached to the upper surface of the bottom 32 by welding, screwing, or the like. A support portion 33 is attached to the front portion of the bottom portion 32. The support part 33 supports the second heat insulating box 22 from below when the machine room unit 3 is mounted on the heat insulating unit 2. The machine room unit 3 is inserted between the second heat insulating box 22 and the mounting table 23 from the front side of the heat insulating unit 2. FIG. 2 shows a state in which the machine room unit 3 is mounted on the heat insulating unit 2. In addition, after the machine room unit 3 is accommodated between the second heat insulation box 22 and the mounting table 23, the pipes 22 </ b> B <b> 1 where the pipes on the refrigeration unit 31 side are exposed from the bottom surface of the second heat insulation box 22. , 22B2 are connected by welding or the like.

  Here, a method for filling the space inside the heat insulating unit 2 (the first space S1, the second space S2, and the flat space S3) with a heat insulating material will be described. First, the heat insulating unit 2 is arranged in an upside down state, and an uncured foamed resin (for example, from the injection hole 28 provided on the bottom surface of the heat insulating unit 2 with respect to the heat insulating unit 2 in that state, for example. Rigid urethane foam) is supplied into the heat insulation unit 2. Since the heat insulating unit 2 has various holes used for screwing or the like, there is no need to positively provide a gas venting hole, but in some cases a gas venting hole is provided. May be. The uncured foamed resin is foamed inside the heat insulating unit 2, while the upper wall space S <b> 13 and the peripheral wall space S <b> 11 in the first heat insulating box 21 on the lower side and the second heat insulating box 22 in the second heat insulating box 22. The space is filled. Finally, the bottom wall space S12 in the first heat insulating box 21 on the upper side and the flat space S3 in the mounting table 23 are filled. As described above, the bottom wall space S12 and the flat space S3 are connected to each other through the opening 27. The reinforcing member 40 is provided with a plurality of circulation portions 43 and the like. Therefore, the foamed resin can reach every corner of the mounting table 23 and the bottom wall of the first heat insulating box 21.

  Thereafter, when the uncured foamed resin is cured inside the heat insulating unit 2, the heat insulating material C filling the first space S1, the second space S2, and the flat space S3 is obtained. In the present specification, the heat insulating material C filled in the first space S1 is represented as a first heat insulating material 21C, and the heat insulating material C filled in the second space S2 is represented as a second heat insulating material 22C. The heat insulating material filled in the space S3 is represented as a mounting table heat insulating material 23C (see FIG. 6). The first heat insulating material 21 </ b> C is continuous with the mounting table heat insulating material 23 </ b> C through the opening 27. That is, the first heat insulating material 21C and the mounting table heat insulating material 23C are connected to each other and integrated. Further, the first heat insulating material 21 </ b> C is continuous with each other through the standing wall opening 26. That is, the first heat insulating material 21C and the second heat insulating material 22C are also connected to each other and integrated. Therefore, the first heat insulating material 21C, the second heat insulating material 22C, and the mounting table heat insulating material 23C are connected to each other and integrated. The injection hole 28 provided in the common bottom panel 24 is appropriately closed after the heat insulating material C is filled.

  As described above, in the allocation vehicle 1 of the present embodiment, the heat insulating material C (the heat insulating material for mounting table 23C) made of foamed resin is provided not only on the bottom side of the first heat insulating box 21 but also inside the mounting table 23. Filled. Since the heat insulating material C is made of foamed resin, it has not only heat insulating performance but also a function of absorbing vibration. Therefore, the vibration from the wheel 4 (the mounting table side wheel 4b, the first heat insulating box side wheel 4a) is difficult to be transmitted to the main body portion 9 side of the distribution vehicle 1.

  Further, in the allocation vehicle 1 of the present embodiment, the bottom surface of the main body 9 (the bottom surface of the heat insulating unit 2) is configured by a common bottom panel 24. Therefore, it becomes the structure which is easy to arrange | equalize the height position (ground pressure) of the wheel 4 (the mounting base side wheel 4b, the 1st heat insulation box side wheel 4a) attached to them. Moreover, in the case of the present embodiment, the wheels 4 (mounting table side wheels 4b, first heat insulating box side wheels 4a) are fixed to the reinforcing member 40 disposed on the upper surface together with the bottom common panel 24. Since the common bottom panel 24 is reinforced by the reinforcing member 40, it is easy to keep the level. By attaching the wheel 4 to such a common bottom panel 24 and the reinforcing member 40, in particular, the height position (ground pressure) of each wheel 4 (mounting table side wheel 4b, first heat insulating box side wheel 4a) is set. Easy to align.

  FIG. 10 is a perspective view of the heat insulating unit 2 in which the upper surface portion of the mounting table 23 is enlarged. When filling the foamed resin into the heat insulating unit 2 as described above, the mounting table 23 can be said to be the place where the foamed resin is most difficult to spread. The mounting table 23 is provided with a reinforcing member 40 that is smaller in thickness than the walls of the first heat insulating box 21 and the second heat insulating box 22 and that easily disturbs the flow of the foamed resin. In particular, it can be said that the peripheral portion of the mounting table 23 (particularly, a portion far from the portion where the injection hole 28 is provided) is a portion where the foamed resin is difficult to spread.

  The ease (flowability) of the foamed resin varies depending on the environment (particularly temperature) in which the foaming resin is filled. For example, if the filling operation is performed in summer when the temperature is high, the foamed resin tends to flow. Conversely, if filling operation is performed in the winter where the temperature is low, the foaming resin is difficult to flow. Since the work of filling the heat insulating unit 2 with the foamed resin has a part that depends on the experience of the worker, the worker may want to check the state of filling of the foamed resin (heat insulating material C) in the heat insulating unit.

  Therefore, in the present embodiment, the front side cover 23A that constitutes the front side of the mounting table 23 is provided so that the operator can easily confirm whether or not the foamed resin (the heat insulating material C) has spread to every corner of the mounting table 23. A transparent window 60 is provided. The window 60 is formed by attaching a transparent plate material (a transparent glass plate, a transparent plastic plate, etc.) to a hole formed so as to penetrate the front cover 23A in the vertical direction. Since the hole of the window 60 is closed with a transparent plate material, the foamed resin does not leak from the hole. By using such a window portion 60, the operator can easily grasp the filling state of the mounting table heat insulating material 23C in the flat space S3.

  One window portion 60 of the present embodiment is provided at each of the front end portions of the mounting table 23 where foamed resin is most difficult to spread. The portions where the window portions 60 are disposed are far away from the injection hole 28 and are outside the rising portion 42 of the reinforcing member 40. In the case of this embodiment, among the side edges along the front-rear direction on the left and right sides of the mounting table 23, the window part 60 is also provided at a substantially intermediate portion in the front-rear direction. As described above, by providing the plurality of window portions 60 in the front-rear direction of the mounting table 23, the filling state of the mounting table heat insulating material 23C in the flat space S3 can be easily grasped.

  FIG. 11 is a perspective view of a heat insulating unit 2X according to another embodiment. This heat insulating unit 2X is obtained by forming more window portions 60X on the front cover 23XA of the mounting table 23X. In addition, the structure of the heat insulation unit 2X is the same as the heat insulation unit 2 mentioned above except having formed many window parts 60X. As shown in FIG. 11, a plurality of window portions 60 </ b> X are formed in a row at the side edge portions along the front-rear direction on the left and right of the front cover 23 </ b> XA of the mounting table 23 </ b> X. Thus, by providing many window parts 60X, the filling condition of the mounting table heat insulating material in the flat space can be grasped more easily.
