  Since the central cam 42 has the structure as described above, the central cam 42 moves not only in the vertical direction but also in the Y-axis direction as shown in the upper part of FIG. It becomes possible.

A first central cam magnet 47, which is a magnet, is attached to the lower portion of the central cam 42.
A second central cam magnet 48, which is a magnet similar to the first central cam magnet 47, is attached to a predetermined portion of the partition box 61. The second central cam magnet 48 is disposed below the first central cam magnet 47 so as to give a repulsive force to the first central cam magnet 47. Thereby, the central cam 42 is urged so as to protrude upward.

  In the central cam 42, a pair of second curved portions 49 having a curved shape is formed at a portion protruding from the upper surface of the second partition member 64. The second curved portion 49 has a shape corresponding to the outer surface of the side wall portion 40-2 of the flat tray 40. By projecting the central cam 42 from the upper surface of the second partition member 64, the second curved portion 49 is in close contact with the outer surface of the side wall portion 40-2 of the flat tray 40.

Next, the usage method of the layout vehicle 10 of this embodiment is demonstrated.
First, the user determines the type of tray to be supported by the tray support unit 19. When the tray supported by the tray support portion 19 is the flat tray 40, the user rotates the support bar 53 so that the cam member 70 has an angle as shown in FIG. By setting the cam member 70 to such an angle, the second partition member 64 is supported by the first support portion 74 of the cam member 70, and the height of the second partition member 64 with respect to the central axis O is the first height. It becomes H1. As shown in FIG. 12, the flat tray 40 is supported by the second partition member 64 and the connecting member 54 having the first height H1. Further, the first partition member 63 is lowered by gravity and comes into contact with the upper surface of the flat plate portion 40-1 of the flat tray 40.
Further, the end cam 35 and the center cam 42 protrude from the upper surface plate 65 of the second partition member 64. The upper surface 64 a of the second partition member 64, the first curved portion 39 of the end cam 35, and the second curved portion 49 of the central cam 42 are in close contact with the outer surface of the flat tray 40.
Thereby, the refrigerator compartment 26 and the warm compartment 27 are partitioned.

Next, an operation when the flat tray 40 is inserted will be described.
First, the user inserts the flat tray 40 between the upper and lower partitioning mechanisms 21 with the door 17 opened. At this time, as shown in FIG. 15, the side wall portion 40-2 of the flat tray 40 lifts the upper first partition member 63 upward. Further, the end cam 35 of the lower second partition member 64 is pressed downward by the side wall portion 40-2 of the flat tray 40. By further pressing the flat tray 40, the flat tray 40 is sandwiched between the first partition member 63 and the second partition member 64 as shown in the upper part of FIG. Further, the end cam 35 and the central cam 42 that are biased by magnetic force are in close contact with the side wall 40-2 of the flat tray 40. Thereby, mixing of warm air and cold air between the refrigerator compartment 26 (second chamber) and the warm compartment 27 (first chamber) is prevented.

When the tray supported by the tray support portion 19 is the double tray 30, the user rotates the cam member 70 from the rotation position as shown in FIG. By rotating the cam member 70, the second partition member 64 is gradually moved upward by the transition surface 78 as shown in FIG.
As shown in FIG. 11, when the second partition member 64 is supported by the flat surface of the second support portion 75, the height of the second partition member 64 with respect to the central axis O becomes the second height H2. As shown in FIG. 12, the duplex tray 30 is supported by the second partition member 64 and the connecting member 54 having the second height H2. Further, the first partition member 63 is lowered by gravity and comes into contact with the upper surface of the connecting portion 33 of the double tray 30. Thereby, the refrigerator compartment 26 and the warm compartment 27 are partitioned.

Two trays can also be carried in from the opposite door 17 and arranged side by side in the Y-axis direction.
In order to arrange two trays in the Y-axis direction, as described above, not only from the door 17 on the opposite side, but also by moving the loaded tray further from the front side to the back side, A tray may be carried to the side.
That is, as shown in FIG. 16, the flat tray 40 carried to the near side in the Y-axis direction is pushed further into the back side, and the side wall portion 40-2 gets over the central cam 42 while pushing the central cam 42 downward. Further, the side wall portion 40-2 of the flat tray 40 lifts the upper first partition member 63 upward, and the flat tray 40 is inserted between the first partition member 63 and the second partition member 64. By further pressing the flat tray 40, the flat tray 40 is sandwiched between the first partition member 63 and the second partition member 64 as shown in the upper part of FIG.

According to the above-described embodiment, when the storage chamber 23 is partitioned by the partition mechanism 21, the end cam 35 and the central cam 42 come into contact with the side wall portion 40-2 of the flat tray 40 together with the end piece 69. The section with the warm room 27 can be made more reliable.
Further, since the end cam 35 and the center cam 42 are urged by utilizing the repulsive force of the magnetic force, the distribution vehicle 10 can be used in an environment where cleanliness is required.

  Further, by rotating the support bar 53 and rotating the cam member 70 fixed to the support bar 53, the height of the upper surface 64a of the second partition member 64 is set to the first height H1 and the second height. It can be changed to H2. Thereby, the partition mechanism 21 which can respond | correspond to the tray from which a shape differs with a simpler structure can be comprised.

  In addition, since the second support portion 75 is a plane parallel to the central axis O of the support bar 53, the second partition member 64 can be supported more stably. Further, the rotational position of the cam member 70 can be stabilized without providing a mechanism for fixing the position of the cam member 70 separately.

  Further, since the first support portion 74 and the second support portion 75 are connected by a transition surface 78 that gradually increases the distance from the central axis O, the support rod 53 is rotated and fixed to the support rod 53. When rotating the cam member 70, the support bar 53 can be rotated more smoothly.

The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to such specific embodiments, and various modifications can be made within the scope of the gist of the present invention described in the claims. Deformation / change is possible.
For example, in the above embodiment, the cam member 70 has the arc-shaped transition surface 78 and assists the rotation operation of the support rod 53. However, the cam member 70 is not provided with the arc portion 73, for example, the first The support part 74 and the second support part 75 may be connected by a plane orthogonal to the second support part 75. That is, the cam member 70 only needs to have the first support portion 74 and the second support portion 75 that are different in distance from the central axis O.

  Further, the cam member 70 of the present embodiment has a structure that supports the lower surface of the second partition member 64, but is not limited thereto, and the lower surface of the upper surface plate 65 (see FIG. 13) of the second partition member 64. It is good also as a structure to support. That is, as long as the second partition member 64 moves up and down by the rotation of the cam member 70, the contact location between the cam member 70 and the second partition member 64 is not limited.

  Moreover, although the partition mechanism 21 of the present embodiment is configured to include the lifting mechanism 66, when only the flat tray 40 is used, the lifting mechanism 66 (second partition member 64) may be omitted. That is, the partition box 61 may be provided with the end cam 35 and the center cam 42.

  The present invention can be applied to a distribution vehicle having an elevating mechanism for elevating and lowering a partition member that contacts the lower surface of the tray.
