FIG. 10 is a perspective view showing an external appearance of a main body support leg part constituting the support body. FIG. 11 is a perspective view showing an appearance of a guide plate constituting the support.

  As shown in FIGS. 1 to 5, a support body 31 that supports the main body box 1 is provided below the main body box 1. As shown in FIG. 9, the support 31 has two main body support leg parts 32 and two guide plates 35.

  The main body support leg parts 32 are provided below the main body box 1 in the front-rear direction. More specifically, the main body support leg part 32 is attached to the lower surface of the main body box 1 in such a manner as to extend left and right on the front side and the rear side of the heat exchange ventilator 30. Each of the two main body support leg parts 32 is formed with a fork insertion port (opening) 33 penetrating in the parallel direction of the main body support leg parts 32, that is, the front-rear direction.

  The fork insertion port 33 is formed so that the main body support leg part 32 provided on the front side and the main body support leg part 32 provided on the rear side are at the same position. When the heat exchanging and ventilating device 30 is transferred by the cargo handling device, the fork of the cargo handling device is inserted through both the fork insertion ports 33 of the main body support leg parts 32 arranged in parallel.

  The guide plate 35 is a plate member provided on a fork insertion path that connects the fork insertion ports 33 of the main body support leg parts 32 arranged in parallel in the front-rear direction. The guide plate 35 is disposed so as to cover the upper surface side of the fork insertion path, that is, the lower surface of the main body box 1.

  Since the lower surface of the main body box 1 is covered by the guide plate 35, it is possible to prevent the fork from coming into direct contact with the lower surface of the main body box 1 when the fork is inserted into the fork insertion port 33. Therefore, it can suppress that the lower surface of the main body box 1 is damaged by a fork.

  The guide plate 35 and the main body support leg part 32 are coupled to each other by screwing. Thereby, rattling of the guide plate 35 and the main body support leg part 32 is suppressed, and the main body box 1 can be supported more firmly.

The fork guide portion 36 is formed so as to extend downward from the guide plate 35 on both left and right ends of the guide plate 35, that is, on both sides of the fork insertion path. More specifically, the fork guide portion 36 is formed by bending the left and right end portions of the guide plate 35 downward along the fork insertion direction (front-rear direction).

  When the fork of the cargo handling device is inserted into the fork insertion port 33, the fork guide portion 36 restricts the fork insertion direction, so that the fork is less likely to shift in the left-right direction. Thereby, when inserting a fork into the fork insertion port 33, it becomes easy to insert reliably without dropping a fork from the front side of the lower part of the main body box 1 to the rear side.

  A floor surface fixing component 34 is attached to the main body support leg component 32. As shown in FIG. 1 and FIG. 4, a fixing hole 34 a for fixing the heat exchanging ventilator 30 to the floor surface is formed in the floor surface fixing component 34. The heat exchange ventilator 30 is fixed to a floor surface or a base portion provided on the floor surface by a bolt or the like through a fixing hole 34a.

  In the present embodiment, an example is shown in which the main body support leg part 32 is divided into two parts that are attached to the lower surface of the main body box 1 in the front-rear direction, but is not limited thereto. For example, the main body support leg part 32 may be divided into three or more parts, and the main body support leg part 32 may be further attached between the main body support leg parts 32 attached to the front side and the rear side.

  Further, in the present embodiment, an example in which the main body support leg part 32 is not divided in the left-right direction is shown, but the present invention is not limited to this. For example, the main body support leg part 32 may be divided at the central portion in the left-right direction so that one fork insertion port 33 is formed in one main body support leg part 32.

  In the present embodiment, the fork guide portions 36 are provided on both sides of the fork insertion path, but the present invention is not limited to this. In other words, the fork guide portion may be provided only on one side of the fork insertion path.

  As described above, the heat exchange ventilator according to the present invention is useful for a floor-mounted heat exchange ventilator that is used by being installed on the floor. Useful for.
