  In the front pillar described in Patent Document 1, the end portions on the windshield side of the outer panel and the inner panel are flanges, and these flanges are overlapped and joined to each other. The end of the reinforcement is also sandwiched and joined to the flange. By the way, although not specified in Patent Document 1, the pillar trim may be assembled to the inner panel in contact with the flange of the inner panel. In addition, some models do not have a reinforcement on the front pillar. Here, if the reinforcement is removed from the front pillar of Patent Document 1, the thickness of the flange is reduced. Then, when the pillar trim is set to contact the flange, a gap is generated between the pillar trim and the flange. Now, the pillar trim must be changed to a different shape.

  The present invention has been made in view of such problems, and an object thereof is to provide a highly versatile vehicle front pillar that can easily respond to specification changes.

  In order to solve the above problems, a typical structure of a vehicle front pillar according to the present invention is a vehicle front pillar, which is a pillar outer that is a sheet metal exterior, and is combined with the pillar outer from the inside of the vehicle together with the pillar outer. A sheet metal first pillar inner that forms a closed cross section, a sheet metal reinforcement disposed between the pillar outer and the first pillar inner, and a resin pillar trim that is further assembled to the vehicle interior side of the first pillar inner, Each of the pillar outer, the first pillar inner, and the reinforcement has a flange that is joined to each other at one end on the windshield side, and the pillar trim has a rib that contacts a surface of the flange of the first pillar inner. Is further replaced by the first pillar inner and reinforcement. The second pillar inner has a second flange joined to the flange of the pillar outer, the second pillar inner being capable of forming a closed cross-section together with the pillar outer. The first pillar inner member and the reinforcement member have a raised portion that is raised away from the flange of the pillar outer so as to be equal to the thickness of the flanges of the first pillar inner member and the reinforcement member.

  By properly using the first pillar inner and the second pillar inner, the pillar trim can be shared in both the specification with the reinforcement and the specification without the reinforcement. Therefore, it is easy to change the specifications, and the costs associated therewith can be reduced.

  The raised portion is formed on the base side of the second flange, and the second flange may be joined to the flange of the pillar outer at an edge where the raised portion is not formed. According to this configuration, even when sound is generated inside the closed cross section formed by the pillar outer and the second pillar inner, it is preferable because the sound hardly leaks to the outside.

  The raised portion has a trapezoidal shape having an upper base and a lower base longer than the upper base on the edge side and the base side of the second flange, respectively, and may be connected to a closed section at the lower base. In the case of the raised portion having this shape, the paint can easily reach the inside of the raised portion during the electrodeposition coating, and it is possible to prevent the air from accumulating and the paint from becoming dirty.

  In order to solve the above-mentioned problems, another typical structure of a vehicle front pillar according to the present invention is a vehicle front pillar, which is a pillar outer that is a sheet metal exterior, and is combined with the pillar outer from the inside of the vehicle. The pillar outer and the pillar inner are provided with a sheet metal pillar inner that forms a closed section together with the pillar outer, a sheet metal reinforcement disposed between the pillar outer and the pillar inner, and a resin pillar trim that is further assembled to the inside of the pillar inner. Each of the flanges of the pillar inner has a plurality of raised portions protruding from the flange of the pillar outer so that a predetermined gap is provided between the flange of the pillar outer and the flange of the pillar outer. The reinforcement is inserted into the gap A plurality of third flange to be joined to the flange and the ridge of Auta, pillar trim is characterized in that it has a rib in contact with the flange surface of the pillar inner.

  In the configuration described above, members other than the reinforcement can be shared in the case of the specification having the reinforcement and the specification having no reinforcement. Therefore, it is easier to change the specifications, and a significant cost reduction can be achieved.

  According to the above configuration, it is possible to provide a highly versatile vehicle front pillar that can easily respond to specification changes.

The second pillar inner 120 is provided with a plurality of second raised portions 124 also on the flange 120b on the vehicle rear side (left side in the figure). The second raised portion 124 is also raised toward the back in the drawing.

  FIG. 5 is a diagram in which the first pillar inner 110 and the reinforcement 112 in FIG. 3 are replaced with the second pillar inner 120. As shown in FIG. 5, the flange 120a of the second pillar inner 120 is joined to the flange 108a of the pillar outer 108 (front flange portion F3). The flange 120b is joined to the flange 108b (rear flange portion F4), thereby forming a closed section E2. Then, the pillar trim 114 is assembled.

  In the configuration provided with the second pillar inner 120, the first raised portion 122 protrudes away from the flange 108 a, and the first raised portion 122 is in contact with the upper rib 116. Further, on the vehicle rear side (downward in the figure), the second raised portion 124 protrudes away from the flange 108 b and contacts the lower rib 118. Therefore, even if the pillar trim 114 is common to the configuration of FIG. 3, no gap is generated between the upper rib 116 and the lower rib 118 and the flanges 120a and 120b. At this time, the 1st protruding part 122 is set so that it may protrude to the thickness which accumulated the flange 110a and the flange 112a of FIG. The second raised portion 124 is also set so as to rise to a thickness in which the flange 110b and the flange 112b of FIG. 3 are overlapped.
