May be integrally connected in the vicinity.

In this case, the load F applied to the upper and lower impact bars 32 and 33 from the upper and lower hinges 21 and 22 can be directly applied to the latch 23 together.
Transmission efficiency is improved, and the rigidity of the entire door can be enhanced.

[0029]

As described above, according to the first aspect of the present invention, the door main frame is sandwiched between the outer panel on the outside of the vehicle and the door trim on the inside of the vehicle and integrally connected to each other. The latch panel is formed with a U-shaped cross section, and a latch that can be engaged with the striker on the vehicle body side is attached to the outer surface of the back wall of the latch panel, and the side end extension of the door trim is latched. The load transmitted to the door at the time of a frontal collision of the vehicle is directly applied to the latch on the back wall of the latch panel by a plurality of cross beams, since it is formed so as to cover the outside except for the meshing portion of the latch panel. The latch is transmitted to the striker on the vehicle body side where the latch engages, and the latch can be covered by the side end extension of the door trim. Therefore, the number of parts is relatively small, and the load at the time of a front collision is transmitted directly to the striker on the vehicle body via the latch, so that the load transmission efficiency is good, the door rigidity can be enhanced, and the appearance around the latch can be improved. It has a good structure.

According to a second aspect of the present invention, in the invention of the first aspect, in particular, since the upper portion of the outer facing wall portion shields the upper edge of the outer panel from the rod, a gap between the upper edge of the outer panel and the door glass is provided. Even when a thinner plate member enters, the upper portion of the outer facing wall portion prevents the thinner member from entering the rod. For this reason, a thin plate-like member such as a gold scale inserted from a gap between the door glass and the upper edge of the outer panel hits the lower end side of the latch release rod, and it is possible to prevent theft due to the opening of the door.
