2. Description of the Related Art Generally, an opening / closing body such as an automobile door is painted with a metallic material such as a metallic paint because of the process, conditions and other reasons, when the door is painted separately from the vehicle body. In some cases, these doors and the car body may not match in color, so they are painted at the same time as the car body.

For this reason, conventionally, in the steps of middle coating and top coating of a vehicle body 52 of a slide door type automobile 51 as shown in FIG. 12, the slide door 53 is temporarily hinged by using a working hinge 54 shown in FIG. The method of attaching to the upper and lower parts a and b of the vehicle body 52 is adopted. This is because the slide portion of the vehicle body 52 cannot be used due to a coating quality problem (a scratch, insufficient coating of the inner plate portion, etc.) in the coating process. That is, if the sliding door 53 is attached to the vehicle body 52 as it is and the work is performed, the workability inside the vehicle body 52 is good when the sliding door 53 is opened, but the inner surface of the sliding door 53 or the vehicle body hidden by the door is hidden. The surface cannot be coated, and on the other hand, when the sliding door 53 is closed, the opposite problem occurs.

Therefore, generally, the sliding door 53 is attached to the vehicle body 52 by a work hinge 54, and the sliding door 53 is replaced with a revolving door to perform painting work. Therefore, the work hinge 54 is composed of the vehicle body side hinge portion 55 and the door side hinge portion 56, and the both hinge portions 5 are
One ends of the reference numerals 5 and 56 are rotatably connected to each other. Further, the other end of the vehicle body side hinge portion 55 is bolted to the vehicle body 52 side from the arrow direction A, and the other end of the door side hinge portion 56 is bolted to the slide door 53 side from the arrow direction B and fixed. There is.

[0005]

However, in the above-mentioned conventional work hinge 54, the vehicle body side hinge portion 55 is provided.
Since the upper and lower portions of the door-side hinge portion 56 are bolted to the corresponding vehicle body 52 or slide door 53, the slide door 5 during the painting operation
3 has a drawback that it is troublesome to attach and detach, and the workability is deteriorated in the painting process using the work hinge 54. Further, in the work hinge 54, the paint attached to the hinge movable portion 57 is easily peeled off due to its structure, which causes a coating failure, which may cause a product failure.

The present invention has been made in view of such circumstances, and an object thereof is to easily attach and detach the slide door when replacing the slide door with a rotary door in a working process, Moreover, it is an object of the present invention to provide a hinge device for working a sliding door for an automobile, which can determine the opening / closing position of the sliding door without using a special jig.

[0007]

In order to solve the above-mentioned problems of the prior art, according to the present invention, a sliding door for an automobile, which is used when a sliding door is replaced with a revolving door and is attached to a vehicle body in a working process. In the working hinge device, either one of a first hinge member having a convex portion and a second hinge member having a concave portion on the vehicle body side and the slide door side is attached, and the convex portion of the first hinge member is provided with The concave part of the second hinge member is fitted and connected so that the upper and lower hinge central axes are inclined.

[0008]

In the working hinge device for a sliding door for an automobile according to the present invention, one of a first hinge member having a convex portion and a second hinge member having a concave portion on the vehicle body side and the sliding door side is attached, Since the concave portion of the second hinge member is fitted and connected to the convex portion of the first hinge member, the upper and lower first hinge members and the upper and lower second hinge members can be easily attached and detached, and the working process Thus, when the sliding door is replaced with a revolving door, the sliding door can be easily attached and detached. Further, since the first hinge member and the second hinge member are connected and arranged so that the upper and lower hinge central axes are inclined, a rotational moment is generated due to the weight of the slide door, and a special lock jig is used. Instead, it will be held open when the slide door is opened and closed when closed.
