Therefore, we attached a hinge to one end of the radiator cover, supported the radiator cover swingably around the hinge, and tried to open and close the radiator opening.

However, when the hinge is attached to the radiator cover, the hinge protrudes from the side surface of the vehicle, so that there is a risk that the hinge comes into contact with the pallet when entering the portal pallet. Moreover, in order to fix the radiator cover supported by the hinge in the closed state, a lock member for that purpose is required, but since the lock member also protrudes from the side surface of the vehicle, there is a risk of contact with the pallet.

The present invention has been made to solve the above-mentioned problems, and to provide a transport vehicle capable of easily opening and closing the cover and suppressing contact with the surroundings even when entering a narrow space. The purpose is to provide.

In order to achieve this object, the transport vehicle of the present invention has an opening on the side surface of the vehicle, a cover that can open and close the opening, and a hinge member that is arranged on one side of the opening and supports the cover so as to be swingable. A cover attachment to which the cover is attached and a lock member for fixing the cover swung by the hinge member at a closed position where the opening is closed are provided. The cover attachment has the cover attached by the lock member. In the state of being fixed in the closed position, the cover and the cover and the cover are arranged inward from the side surface of the vehicle by at least the thickness of the thickest member among the thicknesses of the cover, the hinge member and the lock member. The hinge member and the lock member are formed so as not to project from the side surface of the vehicle , and the cover attachment is directed from one side of the opening to which the hinge member is attached toward the other side facing the other. The cover is provided so as to be positioned at the closed position when the cover swung by the hinge member comes into contact with the cover attachment .

According to the carrier according to claim 1, the cover that can open and close the opening on the side surface of the vehicle is swingably supported by the hinge member and fixed to the closed position where the opening on the side surface of the vehicle is closed by the lock member. .. Therefore, the opening on the side surface of the vehicle can be closed or opened by the operation of fixing and releasing the cover by the lock member. That is, the cover can be easily opened and closed. Further, since the cover is supported by the hinge member, the cover does not fall. Therefore, it is possible to prevent an accident due to the cover falling. Moreover, in a state where the cover is fixed to the closed position by the lock member, the cover, the hinge member, and the lock member are all formed non-projecting from the side surface of the vehicle. Therefore, even when the vehicle enters a narrow space such as a gate-shaped pallet, it is possible to prevent the contact between these members and the pallet or the like.

The cover fitting to which the hinge member supporting the cover is attached has at least the thickness of the thickest member among the thicknesses of the cover, the hinge member, and the lock member when the cover is fixed in the closed position by the lock member. , It is arranged inside from the side of the vehicle. Therefore, in a state where the cover is fixed to the closed position by the lock member, any of the cover, the hinge member, and the lock member can be formed non-projecting from the side surface of the vehicle. Further, the cover attachment is continuously provided from one side of the opening to which the hinge member is attached toward the other side facing the opening, and when the cover swung by the hinge member comes into contact with the cover attachment. The cover is provided so as to be located in the closed position. Therefore, in the cover mounting tool, the position where the hinge member is provided and the position where the cover at the closed position abuts can be brought close to each other. As a result, it is possible to easily realize the alignment when the cover attachment is provided on the vehicle, particularly the alignment for making the cover or the like fixed in the closed position non-protruding from the side surface of the vehicle.
According to the carrier according to claim 2, in addition to the effect of claim 1, the lock member includes a first lock member disposed on the cover and a second lock member disposed on the cover attachment. The cover is fixed in the closed position by engaging the first lock member and the second lock member. Since the second lock member of the lock member is provided on the cover mounting tool, the lock member can be provided on the vehicle without providing a separate mounting member, so that the manufacturing cost of the transport vehicle can be reduced.

According to the carrier according to claim 3, in addition to the effect of claim 1 or 2, the lock member can be fixed to and released from the closed position of the cover by manual operation without using a tool. To. Therefore, since the opening / closing operation of the cover can be performed manually without using a tool, the opening / closing operation of the cover can be further facilitated.
