 Next, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 to 6, below the side door 12 on the passenger side of the cab 11 of the truck, there are provided two upper and lower steps 16 and 17 for raising and lowering. That is, a floor side plate 13 connected to a side edge of a floor panel (not shown) is provided below the door 12. The plate 13 has a first bracket 21 and a second bracket 22 which are fixed to the lower portion of the plate 13 at a predetermined interval, and further has a cross section L fixed between the first bracket 21 and the second bracket 22. It has a letter-shaped shelf 31. A step cover 14 made of resin is attached to the floor side plate 13 so as to cover the lower part of the plate 13, the first and second brackets 21 and 22, and the shelf portion 31.

On the surface of the step cover 14, two steps 16 and 17 are fixed, and two substantially horizontal upper and lower shelves 14a and 14b are formed to cover the lower surface edges of these steps 16 and 17, respectively. Large openings 14c and 14d are formed in the centers of the shelves 14a and 14b, respectively. Steps 16 and 17 are formed in a lattice shape in this example by an aluminum die casting method. A large number of protrusions 16a and 17a are provided on the upper surfaces of the steps 16 and 17 to prevent them from slipping when the passenger moves up and down (Fig. 1).

A pair of columnar protrusions 16b are formed integrally with the step 16 on both vehicle body side surfaces of the step 16 placed on the upper shelf 14a (FIGS. 4 and 5). A pair of through holes 14j into which the pair of columnar protrusions 16b can be loosely inserted are formed in the step cover 14 facing the columnar protrusions 16b (FIG. 4). Further, with the step cover 14 attached at a predetermined position, a through hole 21a is formed in the first bracket 21 so as to face the through hole 14j and a through hole 13d is formed in the lower portion of the floor side plate 13 (FIG. 2). A connecting portion 14m is formed so as to cover the lower step 17 from the projecting side edge of the upper step 16 to the vehicle side edge of the lower step 17 (FIGS. 1 and 2). A bulged portion 14 n is formed at the contact position on the projecting end side of the step 16 of the step cover 14 (FIGS. 2 and 4). The bulging portion 14n forms an interference fit structure that holds the step 16 when the step 16 is pressed against the shelf portion 14a with a certain force (FIG. 2).

The characteristic configuration of this embodiment is that the box portion 32 is formed at the lower part of the step 16 by the shelf portion 31, the brackets 21 and 22, and the connecting portion 14m, and the step 16 can be opened and closed centering on the pair of protrusions 16b. It is located so that it serves as a lid for the box portion 32.

Two recesses 13a are formed substantially at the center of the floor side plate 13 at predetermined intervals, and dented holes 13b are formed on the bottom surfaces of these recesses 13a. The daruma-shaped hole 13b is composed of a small-diameter hole and a large-diameter hole connected below the small-diameter hole. Two convex portions 14g projecting toward the two slabs 13b are formed on the upper rear surface of the step cover 14 at positions facing the two slabs 13b, and these convex portions 14g are formed. A tapping screw 24 is screwed into the tapping hole 14h through a flat washer 23 having a diameter slightly smaller than the diameter of the large diameter hole 13b. Further, mounting holes 14i and 14p for fixing the step cover 14 to a predetermined position of the floorside plate 13 are formed on both sides of the upper end of the step cover 14. Holes 13c and 13e to which a nut (not shown) is welded are formed on the rear surface of the floor side plate 13 facing the holes 14i and 14p (FIG. 2). A mounting screw 28 is screwed into the nut of the hole 13c through the mounting hole 14i, and a mounting screw 29 is screwed into the nut of the hole 13e through the mounting hole 14p.

Two bosses 17b are formed on each side surface of the step 17 placed on the lower shelf 14b (only two of the four bosses are shown), and bolts 27 are screwed into the bosses 17b. The screw holes 17c are respectively formed (FIG. 2). A through hole 14k is formed in the step cover 14 so as to face the boss 17b and allows the boss 17b to be loosely inserted therein. Further, through holes 21b and 22b are formed in the brackets 21 and 22 so as to face the through hole 14k while the step cover 14 is attached to the floor side plate 13 at a predetermined position (FIG. 2).

When the steps 16 and 17 configured as described above are attached to the floor side plate 13, the first bracket 21 and the second bracket 22, first, the steps 16 and 17 are placed on the upper and lower two-stage shelves 14a and 14b, respectively. . At this time, the cylindrical protrusion 16b of step 16 and the boss 17b of step 17 are loosely inserted into the through holes 14j and 14k of the step cover 14, respectively. Next, as shown by the solid line arrow in FIG. 3, the tapping screw 24 screwed through the flat washer 23 into the tapping hole 14h of the convex portion 14g on the upper rear surface of the step cover 14 has a large diameter of the sloppy upper hole 13b. The step cover 14 is temporarily attached to the floor side plate 13 by inserting it into the hole and locking the flat washer 23 to the lower edge of the large diameter hole.

Next, the pair of protrusions 16b of the step 16 loosely inserted into the through hole 14j of the step cover 14 are loosely inserted into the through hole 21a of the bracket 21 and the through hole 13d of the floor side plate 13, respectively. The protrusions 16b are loosely inserted by elastically deforming the bracket 21 or the floor side plate 13.

Then, in order to align the through hole 14k of the step cover 14 with the through hole 21b of the bracket 21 and the through hole 22b of the bracket 22, the bolt 27 is inserted through the through hole 14k with the step cover 14 raised. The step 17 is fixed to the first and second brackets 21 and 22 by being screwed into the screw hole 17c. Further, the mounting screws 28 and 29 are screwed into the nuts (not shown) welded to the rear surfaces of the holes 13c and 13e of the floor side plate 13 through the mounting holes 14i and 14p of the step cover 14, respectively, so that the step cover 14 is fixed to the floor side plate 13.

As a result, the step 16 can be rotated about the protrusion 16b from the shelf portion 14a of the step cover to the position shown by the chain double-dashed line in FIG. 1 (the range shown by the arrow in FIG. 1). In the opened state of this step 16, there is an opening 14c provided in the step cover at the lower part thereof, and inside thereof is constituted by a first bracket 21, a second bracket 22, a shelf portion 31 and a step cover connecting portion 14m. Since there is a box part that can be used, small items such as tools and gloves can be stored. When step 16 is closed and step 16 is placed on the shelf 14a of the step cover 14, the step swell 14n provided on the step cover 14 causes the step 16 to be an interference fit with respect to the swell 14n. Both ends of the step 16 on the projecting side are held so that the step 16 does not float up during traveling.

In the above embodiment, the step 16 is configured such that the cylindrical protrusion 16b is loosely inserted into the holes 14j, 13d and 21a so that the protrusion 16b can be opened and closed. However, between the step 16 and the floor side plate 13. It is also possible to provide a hinge on this and open and close the step 16 with this hinge. Further, instead of the interference fit structure by the bulging portion 14n, or in addition to this structure, a magnet may be provided on the lower surface of the step and the periphery of the opening 14c to prevent the step from being lifted up during traveling by magnetic force. Further, in the above embodiment, two steps are exemplified, but the present invention is not limited to this, and one step or three or more steps may be performed. Further, the protrusion 16b was loosely inserted into the through hole 21a and the through hole 13d by elastic deformation of the bracket 21 or the floor side plate 13, but a male screw was formed at the base end of the protrusion 16b and a female screw was formed at step 16 to make the protrusion 16b. It may be loosely inserted into the through hole 21a and the through hole 13d by screwing into the step 16.
