BACKGROUND OF THE INVENTION Generally,
Some of these types of work vehicles are provided with a cab to protect the operator. However, conventionally, this cab has been integrally assembled to the vehicle body by welding or the like.Therefore, when the cab is mounted on a bed or a freight car of a transportation vehicle such as a truck, it is a tall cab. The ceiling of the car may exceed the legal height or hit the ceiling of the freight car.Therefore, it is necessary to use special type vehicles such as low floor type and freight cars for transportation, and when it is hot in summer, etc. There is a problem that the cab hinders ventilation and the working environment is reduced.

By the way, as disclosed in Japanese Utility Model Laid-Open No. 55-95921, there is a detachable canopy for protecting the operator, but the canopy itself and the ceiling panel are simply supported by columns. Since it is a simple structure, it can be attached and detached with a simple structure. On the other hand, the cab, which has better protection for workers compared to the canopy, has front and rear panels and left and right side panels in addition to the ceiling panel, so it cannot be attached or detached with a simple configuration like a canopy. In fact, the fact is that such things have not been examined.
