As shown in Fig. 3, the portion of the outer panel 11 positioned behind the sub-column 2 includes a side wall portion connected to the flange 14 adjacent to the front windshield sheet 3. 25, the front wall portion 26 and the stepped wall portion 27 connected to the flange 17 abutting the front triangular window glass sheet 4. The outer weather strip 62 attached to the door sash 7 is adjacent to the P ladder. The door sash 7 has a window glass guide groove 63, and the convex edge portions 17 to 19 are provided with an inner weather strip 64. 2, the portion of the reinforcing member a located in front of the sub-column 2 includes a front wall portion 31 connected to the flange 15 adjacent to the front windshield sheet 3, the side wall portion 32 and the flange 16 adjacent to the front triangular window glass The rear wall portion 3" extends substantially parallel to the flange 15 adjoining the front windshield panel 3. The front wall portion 3 and the rear wall portion 33 are defined in a lateral direction as viewed in cross section. A rectangular channel protruding in a direction, and a first ridge line 34 is defined along a linear joint surface between the front wall portion 31 and the side wall portion 32, and the first ridge line is opposite to the inner side of the front wall portion 22 of the outer panel 11. Similarly, A second ridge line 35 is defined along a linear joint between the side wall portion 32 and the rear wall portion 33, and the 131910.doc 1355347 two ridge line 35 is opposite the inner side of the step wall portion 23 of the outer panel 11. The second ridge line 35 Close to the mounting portion 23a of the stepped wall portion 35 of the outer panel 11, but separated by a sufficiently large gap to allow the electrocoat liquid to flow smoothly. As shown in Fig. 3, the reinforcing member 12 positioned behind the sub-column 2 The portion includes a flange portion 15 that abuts the front wall portion 36 of the front windshield sheet 3 The side wall portion 37 and the flange portion 18 are adjacent to the rear wall portion 38 of the door glazing panel 6. The front wall portion 36 extends generally along a plane abutting the flange 15 of the front windshield sheet 3, and is positioned at the sub-column 2 The front portion is similar to the front wall portion 31. The front wall portion 36, the side wall portion 37, and the rear wall portion define a rectangular passage that protrudes in the k-direction direction as viewed in cross section, and along between the front wall portion 36 and the side wall portion 37. The linear joint defines a first ridge 39 and the first ridge is opposite the inner side of the front wall portion 26 of the outer panel 11. Likewise, a second ridge is defined along the linear interface between the sidewall portion 37 and the rear wall portion 38. The line 4 is, and the second ridge line 40 is opposite the inner side of the outer wall portion of the front wall portion 26. The wall portions 3丨 and 36 of the reinforcing member 12 are along the plane of the flange 15 adjacent to the front windshield sheet 3. The extension causes the outer panel to avoid interference from the reinforcing member 2, even if the flat lamp is mounted on the outer surface ii of the flange i 5, as illustrated in the figure and the flap. As shown in Fig. 5, respectively in the sub-column 2 The first ridge lines 34 and 39 of the front and rear reinforcing members 12 are smoothly connected to each other, and the money is divided. The second ridge lines 35 and 4'' of the reinforcing member 12 in front of and behind the sub-column 2 are also smoothly connected to each other. f The position of the 'th-ridge lines 34 and 39 is determined by the front (four) points. The front wall portion in front of and behind the sub-column 2" and the same direction extend from the flange 15 adjacent to the front windshield 3 such that the upper portion 131932.doc 1355347 - the ridges 34 and 39 are broken along the front windshield The side edges of the glass sheet 3 extend while conforming to the slightly curved shape of the front windshield sheet 3 and improve the load transfer efficiency of the front pillar. On the other hand, the lower second ridge lines 35 and 4 略 are slightly vertically offset from each other at the inflection point where the positions of the sub-columns 2 coincide. As shown in Fig. 2, the portion of the inner panel 13 in front of the sub-column 2 includes a side wall portion 45 connected to the flange 16 adjacent to the front windshield 3 and connected to the flange 19 adjacent to the rear wall portion of the front triangular window glass sheet 4. 46.

As shown in FIG. 3, the portion of the inner panel 13 behind the sub-column 2 includes a side wall portion 47 connected to the flange 16 adjacent to the front windshield 3 and connected to the flange 19 adjacent to the rear wall portion of the door glazing panel 6. 48, similar to the inner panel " in front of the sub-column 2. Similarly, the side wall portion 47 and the (four) portion 48 are joined to each other to form a shallow V-shaped cross section that protrudes in the inward direction. In the reinforcing member 12, since the first ridge lines 34 and 39 and the second ridge lines 40 extend in a continuous manner between the portion before the sub-column 2 and the portion behind the sub-column 2, the household can be increased. The front column i resists the mechanical strength of the axial force. At the same time, because the closed section s formed by the stiffener 12 and the inner panel 13 has substantially the same cross-sectional area over their total length, the front pillar produces substantially the same mechanical strength over its overall length. Thus, in accordance with the present invention, the stiffener can be formed from two ridge lines that extend in a continuous manner from the portion of the sub-column to the rear portion of the sub-column such that the change in the cross-section from the sub-column branch in the cross-section can be minimized. Because &, the branch portion is prevented from becoming a weak point, and the mechanical strength of the front pillar against the axial force can be enhanced to improve the collision safety of the vehicle.
