Although FIG. 1 shows the left side of the box 10, the opposite right side has the same structure.

  As described above, the box 10 includes the floor wall 11, the front wall 12, the rear wall 13, the left and right wings 22 that are attached to both sides of the center beam 21, and the left and right sides of the floor wall 11. A luggage room 30 is formed in the interior of the slats 23a and 23b.

  As shown in FIG. 4, the rear frame 16 is fixed to both sides of the rear end portion of the floor wall 11 and extends in the vertical direction, and a horizontal plate that is fixed to the upper end portion of the base plate 31 and extends in the width direction. Plate 32. The base plate 31 and the horizontal plate 32 each have a width direction that is the traveling direction of the vehicle, and a flange 33 protrudes outward in the width direction of the box 10 at the front side portion of the base plate 31. Similarly, the horizontal plate 32 is also provided with a flange 34.

  As shown in FIGS. 4 to 6, a column post 35 is provided at the rear end of the base plate 31. The column post 35 extends in the vertical direction from the lower end to the upper end of the base plate 31. As shown in FIG. 9, the column post 35 includes a rear surface portion 35a, a side surface portion 35b bent at a right angle with respect to the rear surface portion 35a, and a front surface portion 35c bent at a right angle with respect to the side surface portion 35b. These are integrated. The overlapping portion 35 d integrated with the rear surface portion 35 a is welded to the base plate 31, and the front surface portion 35 c is welded to the base plate 31 at a portion that abuts against the base plate 31. As shown in FIG. 9, the column post 35 has a quadrilateral cross section including the base plate 31.

  A reinforcing post 36 is provided at the lower end of the column post 35. As shown in FIG. 9, the reinforcing post 36 includes a side surface portion 36 a that is abutted against the front surface portion 35 c of the support post 35, and a front surface portion that is integrated with the side surface portion 36 a and is bent at a right angle with respect to the side surface portion 36 a. 36b. The side surface portion 36 a is welded to the front surface portion 35 c, and the front surface portion 36 b is welded to the base plate 31. In this way, the lower end portion of the support post 35 and the base plate 31 are connected by the reinforcing post 36 having a L-shaped cross section between the side surface portion 36a and the front surface portion 36b, and the lower end portion of the rear frame 16 is connected. Strength is increased.

  Loads of the open / close doors 17a and 17b and the wing 22 are applied to the rear frame 16, and these loads are combined at the lower end portion of the rear frame 16 and act particularly greatly. Therefore, as shown in the drawing, if the reinforcing post 36 is provided at the lower end of the column post 35, the strength of the lower end of the rear frame 16 can be increased. Thereby, the width dimension W in the traveling direction of the column post 35 can be shortened, and the width dimension L in the traveling direction of the base plate 31 can be shortened. If the width dimension L of the base plate 31 can be shortened in this way, the width dimension L of the rear frame 16 can be shortened, so that it is formed between the inner surface of the front wall 12 and the inner surface of the rear wall 13. It is possible to increase the interval between the gaps. When the frontage interval is increased, it is possible to easily carry in the luggage into the luggage room 30 and carry out the luggage from the luggage room 30 with the wings 22 opened.

  An inclined portion 36c is integrally connected to the upper end portion of the side surface portion 36a of the reinforcing post 36, the inclined portion 36c is inclined toward the base plate 31, and the front surface portion 36b has a width dimension toward the upper end portion. It is getting smaller gradually. The rear end surface of the inclined portion 36 c is welded to the front surface portion 35 c and the upper end surface of the inclined portion 36 c is welded to the base plate 31. Thus, when the inclined portion 36c is provided at the upper end portion of the reinforcing post 36, the strength of the rear frame 16 can be increased by the reinforcing post 36 and the support post 35, and the reinforcing post 36 is provided without providing the inclined portion 36c. Compared with the case where the upper end portion of the lens is a horizontal end surface, even if dust or water droplets hit the inclined portion 36c, the dust or water droplets can be guided to the inclined portion 36c and dropped downward.

  Although the inclined portion 36c is inclined toward the base plate 31 as described above, the inclined portion 36c is inclined toward the rear of the vehicle as indicated by a two-dot chain line 36d in FIG. It is good also as a form, In the form, the side part 36a extends straight to the upper end part of the inclination part 36d. Moreover, as the inclination direction, as shown by the two-dot chain lines 36e and 36f in FIG. 7, it may be inclined toward the base plate 31 and inclined toward the rear of the vehicle. The tip of the inclined portion 36e is in contact with the front surface portion 35c of the column post 35, and the tip of the inclined portion 36e is in contact with the front surface portion 35c through the step portion. As described above, the inclination direction of the inclined portion may be the vehicle front-rear direction, the vehicle width direction, or both directions. In either direction, dust or water droplets can be guided to the inclined portion and dropped downward.

  As shown in FIG. 6, the upper end portion of the reinforcing post 36, that is, the upper end portion of the inclined portion 36c is positioned below the spring-type lock member 28b, which is a lock member for wings. A space is secured between the column posts 35. Thereby, when the operator operates the spring-type lock member 28b, the support post 35 does not get in the way and the operability can be improved.

  As shown in FIG. 7, side frames 37 are provided on the left and right sides of the floor wall 11, and the side frames 37 constitute side portions of the floor wall 11. The side frame 37 extends to the outside of the base plate 31, and a corner reinforcing plate 38 is attached to the outside of the side frame 37 by a screw member 39 adjacent to the reinforcing post 36. The corner reinforcing plate 38 is provided with an operation switch 41 for instructing opening / closing of the wing 22. The operation switch 41 includes an opening switch 41a that is operated when the wing 22 is opened upward, and a closing switch 41b that is operated when the wing 22 is closed.

  As shown in FIG. 8, a side frame connecting plate 37a is disposed outside the base plate 31, and the side frame 37 is sandwiched between the side frame connecting plate 37a and the corner reinforcing plate 38 by a screw member 39. Fixed. The side frame connecting plate 37 a is welded to the front surface of the reinforcing post 36. A frame reinforcing plate 42 is inclined between the base plate 31 and the side frame connecting plate 37a. The rear end surface of the frame reinforcing plate 42 is welded to the front surface portion 36 b of the reinforcing post 36, and the upper end surface of the frame reinforcing plate 42 is welded to the base plate 31. Accordingly, a portion of the lower end portion of the base plate 31 where the support post 35 and the reinforcing post 36 are not provided is reinforced by the frame reinforcing plate 42. The lower end portion of the frame reinforcing plate 42 is covered with a corner reinforcing plate 38 as shown in FIG. Thus, the connection strength between the rear frame 16 and the floor wall 11 can be increased by the corner reinforcing plate 38 and the frame reinforcing plate 42 having a function as an operation panel provided with the operation switch 41.

  FIG. 10 is a cross-sectional view showing the horizontal beam portion of the rear frame 16. A partition plate 43 is provided inside the rear frame 16, and a center beam mount 44 is mounted between the flange 34 and the partition plate 43. The center beam 21 is attached to the rear frame 16 by the center beam mount 44. A hydraulic hose (not shown) is accommodated in the space between the horizontal beam portion of the rear frame 16 and the partition plate 43. The hydraulic hose supplies hydraulic oil to a hydraulic cylinder for opening and closing the wing 22. The width dimension of the horizontal beam portion in the traveling direction is set to be substantially the same as the dimension W of the column post 35.

  FIG. 11 is a front view showing a rear end portion of a conventional box shown as a comparative example, and the same portion as FIG. 7 is shown. 12 is a sectional view taken along line 12-12 in FIG.

  As shown in FIGS. 11 and 12, the strength of the conventional rear frame 16 is ensured mainly by the column posts 35 and the base plate 31. For this reason, it is necessary to increase the width dimension of the support post 35, and as a result, the width dimension of the base plate 31 must also be increased. The conventional base plate 31 has a width dimension of L1, and the column post 35 has a width dimension of W1. The width dimension L1 of the base plate 31 in the conventional rear frame 16 shown in FIGS. 11 and 12 is larger than the width dimension L when the reinforcing post 36 is provided, and the width dimension W1 of the column post 35 is the reinforcing post 36. It had to be larger than the width dimension W when it was provided. Thus, if the above-mentioned reinforcing post 36 is not provided on the rear frame 16, it is necessary to increase the width dimension of the support post 35, and consequently, the width dimension of the base plate 31 must also be increased.

  On the other hand, when the reinforcing post 36 is provided at the lower end portion of the rear frame 16 as in the case 10 of the present invention, as a result of the strength test, even if both the width dimension of the base plate 31 and the column post 35 are reduced, It has been found that the strength required for the rear frame 16 can be secured. Specifically, even if the width dimension L of the base plate 31 is about 60 mm shorter than the conventional width dimension L1, the strength and durability of the rear frame 16 can be sufficiently secured by providing the reinforcing post 36. I was able to.

  Thus, if the width dimension of the rear frame 16 can be shortened, the gap between the inner surface of the front wall 12 and the inner surface of the rear wall 13 of the box body 10 can be increased. It is possible to easily carry in and out the cargo into the box 10 using a forklift or the like without increasing the overall length in the traveling direction, and it is possible to improve the workability.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, the dimension in the vehicle width direction of the front surface portion 36b may be set larger than that shown in the drawing so that the side surface portion 36a of the reinforcing post 36 is flush with the side surface portion 35b of the support post 35.
