Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body structure having an opening and a door at the rear of a so-called box van or the like.

[0002]

2. Description of the Related Art FIG.
2 and 13 are known (Japanese Utility Model Laid-Open No. 7-33).
No. 782). That is, as shown in FIG.
A box van 81 provided at the rear of the vehicle body includes a floor 82, left and right side walls 83 and 84 erected on both sides of the floor 82, and a roof 8 bridged between upper ends of the left and right side walls 83 and 84.
5 are combined. At the rear end, a frame 87 having an opening 86 is provided.
7 is an upper horizontal portion 89 and a vertical portion 9 as shown in FIG.
The upper horizontal portion 89 is formed with a concave portion 88 extending in the vehicle width direction. An end of the upper horizontal portion 89 is connected to an end of the roof panel 92, and the roof 85 includes the roof panel 92 and the upper horizontal portion 89 of the frame 87. The frame 87 has an opening 86.
A pair of Kannon doors 93, 93 that open and close the door are pivotally supported,
A weather strip 94 that is in close contact with the lower horizontal portion 91 of the frame 87 is attached to the periphery of the double doors 93.

In such a configuration, since the concave portion 88 is provided at the rear end of the roof 85 in the vehicle width direction, it functions as a drip channel, and the rainwater dropped on the roof 85 is deposited in the concave portion 88. After flowing in, it flows in the vehicle width direction, flows down the outer surfaces of the left and right side walls 83 and 84, and falls to the ground.

[0004]

As described above, since the rainwater flowing into the concave portion 88 functioning as a drip channel flows down the outer surfaces of the left and right side walls 83 and 84, the rainwater flows on the outer surfaces of the left and right side walls 83 and 84. When the rainwater from the concave portion 88 flows down in a concentrated manner, local water deposits and stains are generated. Therefore, in order to prevent such local adhesion of water residue and generation of dirt on the outer surface, it is conceivable to prevent rainwater flowing into the concave portion 88 from traveling on the outer surfaces of the left and right side walls 83 and 84. In other words, the configuration is such that the rainwater flowing into the concave portion 88 flows down the inner surfaces instead of the outer surfaces of the left and right side walls 83 and 84, thereby eliminating the occurrence of local adhesion of water scale and dirt on the outer surfaces. Can be.

[0005] However, in this conventional structure, if the rainwater flowing into the recess 88 is merely to flow down the inner surfaces of the left and right side walls 83 and 84, the rainwater is discharged from the box van 81.
Therefore, the waterproof property of the box van 81 cannot be secured. Therefore, in order to prevent the adhesion of local water deposits and the generation of dirt on the outer surfaces of both side walls 83 and 84 while ensuring the waterproofness of the box van 81, simply use the recess 8.
In addition to the structure in which the rainwater flowing into the inside 8 flows down the inner surfaces of the left and right side walls 83 and 84, the rainwater flowing down the inner surfaces of the left and right side walls 83 and 84 is
A waterproof structure must be provided so as not to flow into the room, and the structure becomes complicated.

The present invention has been made in view of such a conventional problem, and it is possible to prevent local adhesion of water scale and generation of dirt on the outer surfaces of the left and right side walls without complicating the structure. It is an object of the invention to provide a rear structure of a vehicle body as described above.

[0007]

In order to solve the above-mentioned problems, the present invention provides a floor, left and right side walls erected on both sides of the floor, and a roof bridged between upper ends of the left and right side walls. An opening is provided at the rear end, and a door for opening and closing the opening is provided, and a weather strip that seals tightly with the door is provided on an inner peripheral portion of the opening. In the mounted vehicle body, a drip channel extending in the vehicle width direction is integrally formed on the roof, outside the vehicle body from a mounting position of the weather strip.

In this configuration, if rainwater flowing into the drip channel flows down the outer surfaces of the left and right side walls, local water deposits and dirt are generated on the outer surfaces of the left and right side walls. In order to avoid the adhesion of dirt and the generation of dirt, it is necessary to cause the rainwater flowing into the drip channel to flow down inside the left and right side walls. At this time, since the drip channel is formed outside the vehicle body rather than the mounting position of the weather strip that seals the opening and the door, the drip channel does not need to be provided with a special structure for securing waterproofness to the room. If the structure is such that rainwater from the channel simply flows down inside the left and right side walls, a vehicle body structure is achieved in which rainwater does not enter the room and local water deposits and dirt do not occur on the outer surfaces of the left and right side walls. You.

In another aspect of the present invention, the roof comprises a roof panel and a roof rail made of an extruded aluminum material joined to a rear end of the roof panel. A channel is formed in the roof rail. Therefore, the drip channel can be formed at the same time as the extrusion molding of the roof rail, and the drip channel can be easily provided on the roof.

Further, in another configuration of the present invention, the left and right side walls are constituted by a side panel and a pillar joined to a rear end of the side panel and pivotally supported by the door. A space is provided inside the pillar to allow water in the drip channel to flow down. Therefore, without processing the side panel, which is a large part having a large area, and by easily processing the pillar, which is a much smaller member, rainwater does not enter the room and the left and right side walls can be formed. A body structure is achieved in which local water deposits and dirt do not occur on the outer surface of the vehicle.

Further, since the pillar is made of an extruded material made of aluminum, it is possible to form a space for flowing water in the drip channel inside the pillar at the same time as the pillar is extruded. In addition, it is possible to easily achieve a vehicle body structure in which rainwater does not enter the room and local water deposits and stains do not occur on the outer surfaces of the left and right side walls.
