[0002]

2. Description of the Related Art Conventionally, for example, a wrap-around preventing cover panel is swingably mounted on a truck, for example, so as to cover a side surface of the truck below a loading platform. This cover panel is provided to prevent a passenger or the like from being caught by the rear wheels during traveling, and the cover panel is swingable for refueling. Such a cover panel for preventing entanglement is attached to a side edge of the truck bed via a steel hinge.

[0003]

However, if the wind-in prevention cover panel is mounted via a steel hinge as in the prior art, the work of mounting the cover panel is very troublesome, and the number of mounting steps is large. However, there is a problem that it is very difficult for a worker who is unfamiliar and unskilled to obtain the mounting accuracy. Also, the hinges are made of steel, each of which is heavy, which increases the weight of the entire truck, and a large number of hinges appear on the outer surface of the side edge of the loading platform, so that the appearance is very poor and unfavorable in appearance. In addition, steel hinges have a problem in that rust is generated over a long period of use, and furthermore, rainwater seeps from the hinge mounting portion, and the rainwater may enter the inside of the cargo bed.

In order to eliminate the above-mentioned problems, the present applicant has proposed a first member made of an extruded aluminum member having a first hinge component, and a first member made of an extruded aluminum member having a second hinge component. It has been proposed to combine the second member with a second member to form a rotating hinge, for example, to simplify the swinging mechanism of the cover panel (for example, Japanese Patent Application No. 5-5095).
No. 7).

According to the previously proposed rotary hinge, the cover panel can be swingably mounted on the truck bed, so that the conventional steel hinge is not required to be mounted, and the mounting accuracy can be improved. Large bond strength,
Further, the weight can be reduced, and the aesthetic appearance of the mounting portion such as the cover panel can be improved.

However, in the previously proposed rotary hinge, the combination of the first and second members is changed by sliding one of the first hinge components to the other second hinge component from one end thereof in the longitudinal direction. However, it requires a lot of man-hours for installation, for example, it is slightly troublesome to install the cover panel to prevent the wind-up from getting under the truck bed. There is a new problem that it is not easy.

An object of the present invention is to solve the above problems,
Attachment and removal of the winding prevention cover panel and the like to and from the first member attached to the truck bed can be easily performed from the side surface of the bed, and the number of mounting steps can be greatly reduced. Accordingly, it is an object of the present invention to provide a rotating hinge that is very easy to remove and attach when repairing a cover panel or the like.
