The support portion 33 is a portion that supports the second heat insulation box body 22 from the lower surface side in a state where the machine room unit 3 is mounted between the second heat insulation box body 22 and the mounting table 23. In particular, the support portion 33 is in contact with the front portion of the second heat insulation box 22 and supports the second heat insulation box 22. The support part 33 of this embodiment supports the 2nd heat insulation box 22 with the fixed pillar 25 interposed between the 2nd heat insulation box 22 and the mounting base 23. FIG. The fixed column 25 is a columnar member obtained by processing a metal plate, and is erected on the left front corner of the mounting table 23.

  FIG. 2 shows a state in which the machine room unit 3 is mounted on the heat insulating unit 2. Since the 2nd heat insulation box 22 protrudes in the front side from the 1st heat insulation box 21 so that space may be formed below, it has the composition which is easy to hang down under its own weight. In order to prevent the second heat insulation box 22 from hanging down, a support portion 33 is provided on the front side of the machine room unit 3. The support part 33 consists of what processed metal board | plate materials. An upper end (a contact portion to be described later) of the support portion 33 contacts the front side portion of the lower surface of the second heat insulation box 22 to support the second heat insulation box.

From the rear end of the contact portion 33C, there is provided a plate-like inclined guide portion 33D that is inclined so as to descend toward the rear side (the direction in which the machine room unit 3 moves when mounted). The inclined guide portion 33D is also formed by processing a metal plate material, and is connected to the contact portion 33C. That is, the contact portion 33C and the inclined guide portion 33D are manufactured by bending one plate-like member.

  FIG. 6 is a side view of the support portion 33. When the machine room unit 3 moves between the second heat insulation box 22 and the mounting table 23 toward the first heat insulation box 21 when attached, the inclined guide portion 33D is in a second heat insulation state that hangs down by its own weight. It contacts the lower part of the box 22 before the contact part 33C (see FIG. 6). In this state, when the machine room unit 3 is further pushed into the first heat insulation box 21 side (in the direction of the arrow 100 in FIG. 6), the lower part (corner portion 22c) of the second heat insulation box 22 is Then, it moves along the surface of the inclined guide portion 33D and moves to the upper surface of the contact portion 33C. That is, the inclined guide portion 33D has a function of guiding the second heat insulating box 22 so as to be placed on the contact portion 33C. Thus, even when the second heat insulation box 22 hangs down by its own weight, it is possible to lift the second heat insulation box 22 simply by pushing the machine room unit 3 closer to the first heat insulation box 21 side. And the machine room unit 3 can be accommodated in the predetermined space (machine room 3a) between the 2nd heat insulation box 22 and the mounting base 23. FIG. Thus, in this embodiment, it is easy to perform the installation operation of the machine room unit 3.

  After the machine room unit 3 is inserted between the second heat insulation box 22 and the mounting table 23, the machine room unit 3 is appropriately fixed to the heat insulation unit 2 side by screws or the like. For example, the inclined guide portion 33D is provided with notches 33D1 and 33D2 through which screws are passed, and the screws are passed through the notches 33D1 and 33D2 from below to above to form a plate-like shape.

  Here, an operation of replacing the condenser fan 37 (fan motor) that is a component of the refrigeration unit 31 during maintenance of the distribution vehicle 1 will be described. Although the condenser fan 37 is one of the components constituting the refrigeration cycle, the condenser fan 37 is independent of the configuration in which the refrigerant circulates. That is, it is preferable that the replacement operation of the condenser fan 37 is performed without cutting the refrigerant flow paths (the pipes 38, 39, etc.).

  In the present embodiment, the bent portions 38a and 39a that are bent in a U-shape are provided in the pipe 38 and the pipe 39 that are connected to the evaporator, among the components that constitute the refrigeration cycle. FIG. 5 is an explanatory view showing a state in which the machine room unit 3 is pulled out from the heat insulating unit 2 to the front side so that a space is formed on the back side of the machine room 3a.

When the machine room unit 3 is pulled out toward the front side of the ration wheel 1 so that (the distance L between the bottom portion 32 and the wall surface 21b) is formed, the bent portions 38a and 39a are respectively U-shaped. The plastic deformation is performed so that the interval inside the portion bent in the direction is narrowed.

  For example, the bent portion 39a is plastically deformed so that the inner distance (distance X1 in the front-rear direction shown in FIG. 5) of the U-shaped portion is reduced. Further, with respect to the other bent portion 38a, as shown in FIG. 6, when the machine room unit 3 is pulled out in the direction of the arrow 101, the distance X2 inside the portion bent in the U-shape is reduced. Plastically deformed.

  Thus, even if the pipes 38 and 39 are still connected to the evaporator side, the bent portions 38a and 39a are appropriately plastically deformed so that the pipes 38 and 39 are displaced in the front-rear direction. Is acceptable. That is, the position of the machine room unit 3 can be moved from the heat insulation unit 2 side to the front side to some extent without disconnecting the pipes 38 and 39 from the evaporator side.

  As described above, when a gap (for example, a gap having a distance L of about 10 cm) is ensured on the back side of the machine room unit 3, the operator inserts his hand into the gap from the right side of the layout vehicle 1, Exchange work can be performed. Then, the operator can perform a removal operation of the condenser fan 37, a removal operation of the removed condenser fan 37 to the outside, a replacement operation of a new condenser fan 37, and the like.

  In addition, when it is desired to completely remove the machine room unit 3 from the heat insulation unit 2 side, the fixing and connection between the machine room unit 3 and the heat insulation unit 2 side are released by appropriately cutting the pipes 38 and 39. Thereafter, the machine room unit 3 is moved in the direction opposite to that at the time of mounting.

  As described above, since the machine room unit 3 is detachable from the heat insulating unit 2 side in the allocation vehicle 1 of the present embodiment, workability at the time of maintenance or assembly can be efficiently performed.
