DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application The present invention relates to a vehicle body structure around a lower part of a windshield when a vehicle body is constructed.

b. Prior art Conventional technology includes the ones shown in Figures 1 to 3. In each figure, / is a windshield opening, 2 is a dash upper panel forming the lower wall of this opening, and g is a dash upper panel that forms the lower wall of this opening. The cowl top panel joins with this dash upper panel λ to form a box-shaped cross section and forms the outside air intake section, and the cowl side panel that partitions the side of the outside air intake section! is joined to the lower end of the dash upper panel λ and is connected to the engine compartment E.
lOv'i to the dash lower baneno that separates the F room and F room R.
Outer panel with the front pillar forming the side wall of the opening/,! and the inner panel /l form a box-shaped cross section and are joined together by -C. /S is a hinge pillar that is joined to the front pillar 1O17)'F end and supported via a door hinge; /A is a dash side panel that is joined to this hinge pillar stub; It is joined to the side end portion 2a. 20 is the hood ledge panel forming the side wall of the engine room E, and 20 is the front side member 1.
Reference numeral 72 indicates a roof panel forming the opening/upper wall, a knob forming the door opening, and a side sill forming the lower wall of '16, which is joined to the hinge pillar/9 at the front end. 27 is a sealant applied from the lower/biased part of the front pillar outer panel 12 to the dash side panel 1AVC, and 2g is the connector channel joined to the lower end of the front pillar outer panel/2. It is designed to be joined to the side end 2a of the panel 20. (Japanese Unexamined Patent Publication No. Sho!!-G3970) However, in such a heavy body structure, the sealant 27 applied to the front pillar outer panel 2 and the dash site nozzle/6 is also applied to the third part. As shown in the figure, there is a part where the sealant is not applied, and there is a risk that water may enter from this part as shown by the arrow X, causing a seal failure that causes the interior to swell. For this reason, in order to prevent the seal from breaking, a large amount of sealant is loaded into the seal 5 so that the seal line is continuous, but this makes seal management difficult and results in poor manufacturability.

C1 Purpose of the Invention This invention 1'i has been made in view of the above-mentioned conventional situation, and it is an object of the present invention to obtain a heavy body structure with good manufacturability, which can be easily and reliably sealed by simplifying the structure.

d0 Structure of the Invention In order to achieve this object, in this invention, the lower end of the front pillar outer panel above the dash side panel is extended forward, and a dash hot spring is attached to this extended part inward in the vehicle width direction. A bent part facing the bottom surface of the side end of the channel is formed, and a sealant is interposed between the bent part and the regular end of the dash upper panel, while the upper end of the dash side panel is also extended forward. However, in the actual gun example shown in Fig. Z and Fig. 5, the part 1 (1) is completely the same as the conventional one.
The same reference numerals are used to omit the explanation.

The upper part of the periphery of the window mold opening is the front end of the roof panel nozzle, and the front pillar, 7
(In 7, the lower part is composed of an outside air intake part formed by a Datsusure panel and a cowl tog panel.Engine room E and Togaku R are defined by Datsusure lower panel L, The rear end of the hood ledge panel/g is joined to partition the side wall of the engine room E.The upper part is the roof side 5, and the lower part is the side sill 2g. The front consists of the front pillar and the dash side panels.

And the front pillar? Fold the lower end of the outer panel 3 forward by 3μ and bend the upper end of this extended portion 3μ inward in the vehicle width direction.This bent portion 36 is the IH11 end of the dash panel panel It is made to face the bottom surface of part 2a. An extension portion 9 extends from the outer surface 3 cores a extending in the vertical direction at the lower end of the front pillar outer panel 320.
The outer surface of 17? An L-shaped connector panel jO is joined across the ta, and one side of the connector spring λ extends outward in the river width direction. 2a is overlapped and joined W
, has been. A sealant 27 is loaded on the inside of this joint W1, that is, on the part where the bent part 3 and the bottom of the end of the dash Atsuba panel face each other,
Efforts are being made to prevent water from entering Togaku R. At the lower end of the front pillar outer panel 3, including the extension part 3μ, the upper end 0a of the dash side panel O is located outward in the river width direction, and the dash side panel θ is located outward in the width direction of the vehicle. They are joined so as to be repositioned inward.

In order to create such a joint structure, the upper end of the dash side banelder θ is also extended forward 4t2, and this extension 4t
The upper end of 2 and the extension 3μ of the front pillar outer panel 32 are joined W2.To describe the assembly of the heavy components with this configuration, the front pillar outer panel 3, the dash side panel O, and the connector is assembled and joined in advance before being joined to the dash atsuba panel. After that, apply sealant No. 27 to the front pillar outer panel 3, and finally pull out the dash attachment panel, which was previously joined together with the cowl tog panel and cowl side panel, from above, and then pull the dash attachment panel and the connector joint together. (Nel! θ
○Therefore, from the lower end of the front pillar outer panel 3 unit to the dash side panel <1
Since the application surface of the sealing agent 27 is formed continuously up to the upper part of 0, there are no breaks in the seal, and the occurrence of seal defects can be easily and reliably prevented.

Therefore, there is no need for strict seal management as in the past, and the manufacturability is extremely good.In addition, the front pillar outer panel 3.2 and the dash side panel θ
By extending the M and 4t2 forward respectively, the sealing surface is formed to be continuous, resulting in an extremely simple m-body structure.Furthermore, the front pillar outer bis: /I/32 and the dash Side panel 0 refers to the front pillar ([+11 + Ji, since it is joined so that it is located on the outside in the width direction)
The water flowing down from the side end 2a of L/2 is less likely to enter the room from the f;HHAb joint of the front pillar outer panel 3.2, and the intrusion prevention property is improved. Moreover, in order to further ensure water intrusion prevention and rust prevention, a special feature is added to the joining joint between the front pillar outer panel 32 and the dash side panel O. Two points Q ti in the diagram

(In addition, it is also possible to position the dash side panels outward and position the front pillar outer panel 3.2 inward and join them, but in that case, apply sealant ≦0 to the joint joint.) However, in the case of Example σ), application of the sealant 6θ is not necessarily required. ) And yet another connector panel! Dash upper Banelko's 1ll11 using θ
Since the joint W1 is made to join the end 2a, it is possible to spot weld the overlapping part from the top and bottom of the tungai 4 yellow by pulling F, and perform automatic welding (for example, automatic welding using a welding robot). This method is easy to perform, and is preferable from the viewpoint of improving the welding strength of heavy bodies. In addition, without using the connector panel θ, the front pillar outer panel 3-! According to the present invention, the sealing agent may be directly connected to the sealing portion 2a of the dash upper panel λ (Ill) at the bent portion 36 of the dash upper panel λ inside the loading portion 27. , rather than complicating the structure, it was simplified so that the sealant applied surface could be read as a line.
Application of sealant to ensure sealing performance is f7(j
