Further, at least one perforation is further formed in the top case, the elastic pin is inserted into the perforation of the top case, and the volume of the top case is expanded by a predetermined interval by the elastic fin, And a technique for increasing waterproof performance.

Generally, a driver's seat of a heavy equipment such as a forklift, a bulldozer, a crane, etc. is provided with a display module for informing various conditions of a hydraulic device, a motor, etc. according to general conditions such as heavy fuel, electricity, (VECU, VEhicle Control Unit) for controlling the air conditioner, the wind direction, the automatic switching, the washer, the defrosting, the menu selection, the cancellation, and the sound control for the operation of the special equipment.

The vehicle control device is usually housed in a box-shaped case and disposed in a heavy equipment for protection from an external environment. However, in general, the heavy equipment vehicle may have irregular fluctuations in its use environment. In this case, there is a possibility that the water or other liquid flow used by the driver may be poured by the swing of the driver's seat, There is a possibility that it may cause a large damage if it is introduced into the apparatus.

In addition, heavy-duty vehicles generally have a structure that is less likely to be protected from the outside environment than a general passenger vehicle. For example, heavy-duty vehicles continue to operate at outdoor construction sites, such as construction sites, and are frequently parked at construction sites for a long time after exposure.

However, since the driver's seat of a heavy-duty vehicle is designed to be relatively more open than a general vehicle, the open environment of such a heavy-duty vehicle tends to easily expose an internal device of the heavy-duty vehicle to the external environment. Also in this case, when water such as rainwater flows in from the outside as in the case of rain, if the inflow water is introduced into the case of the vehicle control unit, there is a problem that the vehicle control unit may fail.

Therefore, the vehicle control unit case necessarily requires a waterproof structure to manufacture the vehicle control unit case.

In order to prevent this, as shown in FIG. 3, a groove for receiving the sealing member is formed on the upper surface of the bottom case. However, the sealing member mounted in the groove is not shown in FIG. As a result, the elastic force provided by the sealing member can be largely lowered by the portion introduced into the inside of the groove, thereby increasing the possibility that the liquid flows into the gap between the top case and the bottom case .
