The rear end portion 32 </ b> A of the upper panel member 32 extends so as to be inclined downward toward the rear side, and is arranged so as to overlap with the upper end portion 33 </ b> A of the rear panel member 33 from the front side. For this reason, the fastening member 35 is arranged in a posture that descends and slopes toward the front side.

  Moreover, the cooling storage 10 is provided with the top plate 40 which comprises the top surface 40A of the cooling storage 10, as shown in FIG. The top plate 40 has a rectangular shape that is long in the left-right direction in plan view, and covers the heat insulating box 20 and the machine room 11 from above. As shown in FIGS. 5 and 6, the top plate 40 is supported from below by the upper surface 20 </ b> F of the heat insulating box 20 (upper panel member 32) and the upper surface 50 </ b> A of the top plate support 50. The upper surface 20F and the upper surface 50A are horizontal surfaces, and are flush with each other as shown in FIG. The top plate 40 has a shallow box shape opened downward. As shown in FIG. 5, the top plate main body 41 constituting the horizontal top surface 40 </ b> A and the front end of the top plate main body 41 downward. A top plate front end portion 42 that extends and a top plate rear end portion 43 that extends downward from the rear end of the top plate main body portion 41 are provided. The top plate main body 41 and the top plate rear end portion 43 are connected so as to be orthogonal to each other.

  For this reason, between the corner | angular part comprised by the top-plate main-body part 41 and the top-plate rear-end part 43, and the upper end part 33A (and rear-end part 32A of the upper panel member 32) of the rear panel member 33, An accommodation space S1 having a triangular shape in side view is provided, and the head of the fastening member 35 is accommodated in the accommodation space S1. It is possible to provide an accommodation space for accommodating the head of the fastening member 35 by forming the rear end portion 32A of the upper panel member 32 in a step shape. It is necessary to bend the wire 32 twice to increase the number of steps. In this regard, in the present embodiment, since the rear end portion 32A is inclined, the accommodation space S1 can be formed by only bending the upper panel member 32 once.

  Further, a concave portion 33B opened to the rear side is formed at a position below the upper end portion 33A in the rear panel member 33. A projection 43A configured by causing a part of the rear end portion 43 of the top plate to bulge forward is fitted into the recess 33B. Thereby, the top plate 40 is configured to be engaged with the rear panel member 33. Further, when the top plate 40 is assembled to the heat insulating box 20, after the front end portion (latching portion 46 described later) of the top plate 40 is locked to the extending member 60 (described later), The end 43 is lowered with respect to the heat insulating box 20, and the protrusion 43A is fitted into the recess 33B. At the time of this assembly, the lower end 43B of the top plate rear end portion 43 may be caught by the overlapping portion 37 of the rear end portion 32A and the upper end portion 33A. Since the surface of the overlapping portion 37 is an inclined surface inclined downward toward the rear side, when the lower end 43B is caught on the overlapping portion 37, the operator pushes the top plate 40 downward. Thus, the lower end 43B slides on the inclined surface of the overlapping portion 37, and the top plate rear end portion 43, which is a sheet metal, can be bent and deformed rearward. Thereby, the lower end 43B can be displaced below the overlapping portion 37, and after the displacement, the rear end portion 43 of the top plate is elastically restored, whereby the projection 43A is fitted into the recess 33B. If the rear end portion 32A of the upper panel member 32 has a stepped shape, it is difficult for the top plate rear end portion 43 to bend and deform when the lower end 43B is caught by the rear end portion 32A. Assembling property will be lowered.

  The top plate support section 50 supports a portion 47 (a portion disposed above the machine chamber 11, see FIGS. 1 and 2) that protrudes from the heat insulating box 20 to the side (machine room 11 side) of the top plate 40.
