Therefore, when the water on the seat stand flows out toward the main plate after rain, cleaning, cold storage work, or the like, the water first drops between the seat stand and the main plate.

The falling water collects between the seal member and the main plate and further flows out along the main plate to the front or the rear of the seat stand. Therefore, the above-mentioned water does not fall on the electrical components arranged under the seat stand. The same applies to water that has drooped down the side wall of the main plate.

Further, when water between the seal material and the main plate leaks from the seal material, the water is collected in the drain groove. Furthermore, this water is carried to the rear panel, for example, by the drainage channel and discharged from the rear part of the machine base. Therefore, no water leakage will occur in the electrical components.

As described above, in the present invention, the water dropped between the stand support and the main plate is
First, the sealing material can prevent water leakage toward the electrical components. And even if water leaks from the sealing material, there is a drainage groove inside, so that water is collected in the drainage groove and discharged from the rear part of the machine base to prevent water leakage to electrical components. it can. As described above, in the present invention, the sealing material and the drainage groove doubly prevent water leakage.

Further, the drainage groove is provided in a stand support for supporting the seat stand. Therefore, the stand support has three functions, that is, the function of supporting the seat stand and the function of the drainage groove, and the function of disposing the sealing material, and the structure is simple. As described above, according to the present invention, it is possible to provide an industrial vehicle that does not require a separate member such as a roof plate, has a simple structure, and is resistant to water leakage.
