The receiving members 212 are provided in such a manner that their inner surfaces face each other, and the receiving roller 212a is rotatably disposed.

  Such a receiving member 212 is disposed on the outer surface of the pair of left and right deck bases 24 erected on the bottom surface of the storage chamber 2 via the rail member 23. Here, the rail member 23 is configured by joining the first rail portion 231 and the second rail portion 232 back to back with each other. The rail members 23 are also a pair of left and right ones like the deck base 24 and the receiving members 212.

  The first rail portion 231 is a long rod-like body whose longitudinal cross section is substantially U-shaped and whose longitudinal direction is the longitudinal direction. The first rail portion 231 allows the entry of the base roller 24a provided on the outer surface of the deck base 24, and rolls the base roller 24a.

  The second rail portion 232 is a long rod-like body whose longitudinal cross section is substantially U-shaped and whose longitudinal direction is the longitudinal direction. The second rail portion 232 allows the entry of the receiving roller 212a, and rolls the receiving roller 212a.

  As described above, the rail member 23 is slidably movable along the front-rear direction with respect to the deck base 24 by the base roller 24a entering and rolling the first rail portion 231.

  The receiving member 212 is slidable in the front-rear direction with respect to the rail member 23 when the receiving roller 212a enters and rolls on the second rail portion 232 of the rail member 23. That is, the receiving member 212 is provided slidably along the longitudinal direction with respect to the deck base 24 via the rail member 23.

  As a result, the placement unit 21 is provided slidably along the front-rear direction with respect to the case body 1, and the deck 20 having the placement unit 21 constitutes the bottom of the storage chamber 2. A storage area S is formed between the pair of left and right deck bases 24 below the placing portion 21.

  The fence portion 22 is a light transmitting flat plate member made of, for example, a resin material such as an acrylic resin, and the left and right direction is the longitudinal direction. The fence portion 22 is supported by a pair of left and right arm members (support members) 25.

  The arm member 25 swings around the central axis of the fastening member 251 by attaching the rear end 25a to the front end portion of the receiving member 212 via a fastening member 251 such as a screw, as also shown in FIG. It is provided to be movable. That is, the arm member 25 is provided swingably along the vertical direction. The arm members 25 sandwich the fence portion 22 at their front end portions 25b.

  Under normal conditions, the lower end edge portion of the rear end portion 25a of the arm member 25 abuts against the restriction piece 212b formed on the outer surface of the receiving member 212, whereby the downward swing is restricted and the arm member 25 is placed It protrudes to the front rather than the part 21.
