  That is, since the upper ends 82a and 82a of the second support walls 82 and 82 are connected to the joint wall 84, the second support walls 82 and 82 can be connected using the joint wall 84. Thereby, while being able to simplify the structure of the 2nd support member 52, the enlargement to the upper direction of the 2nd support member 52 can be suppressed.

  As shown in FIGS. 6 to 8, in the vehicle door 20 (see FIG. 1), the first support wall 62 and the second support wall 82 are joined at the second joining points 77 and 77. The connection strength between the first support member 51 and the second support member 52 can be further increased.

  In the vehicle door 20 (see FIG. 1), the second support member 52 includes a latch-side connection wall 85 that connects the second support walls 82 and 82 and is joined to the latch reinforcing member 42. 85 and the joining wall 84 are spaced apart from the inner panel 31 in the longitudinal direction of the vehicle body, and the latch mechanism 28 includes the inner panel 31, the second supporting walls 82 and 82 of the second supporting member 52, the joining wall 84, and The latch mechanism 28 can be protected by the inner panel 31 and the second support member 52 because the latch mechanism 28 is disposed in the space B1 surrounded by the latch side connecting wall 85.

  In the vehicle door 20 (see FIG. 1), the first support wall 62 includes a first opening 71 in the vicinity of the lower connection wall 66, and the second support wall 82 has a second in the vicinity of the latch side connection wall 85. Since the opening 91 is provided, the outer panel support member (outer surface support member) 43 formed by the first and second support members 52 can be reduced in weight.

  Since the distance between the lower connecting wall 66 and the first opening 71 and the distance between the latch side connecting wall 85 and the second opening 91 are substantially the same, for example, the tall vehicle door 20 of the care vehicle 10 The common vehicle 210 (see FIG. 11) can be pulled out from the first opening 71 or the second opening 91 by using the latch mechanism 28 in common with the vehicle door 220 having a short height. Is possible.

As shown in FIGS. 6 to 8, in the vehicle door 20 (see FIG. 1), the second support member 52 is superimposed on the vehicle exterior side of the first support member 51.
In a vehicle in which the rear opening 21 such as the care vehicle 10 is opened to a lower position of the vehicle body 11, for example, when bumped into another vehicle, the bumper (the member that protrudes most in the horizontal direction) of the other vehicle is the second. It often collides with the support member. Therefore, by overlapping the second support member 52 on the vehicle outer side of the first support member 51, it is possible to prevent the bonding between the first support member 51 and the second support member 52 from being peeled off. Can support the load.

  In the vehicle door according to the present invention, as shown in FIG. 11, the vehicle 10 is a care vehicle. However, the vehicle door is not limited to this, and if the vehicle needs to change the height of the vehicle door, It is not limited to general vehicles or nursing care vehicles.
