[0002]

2. Description of the Related Art Some roofs of vehicles such as trucks are provided with a roof carrier for loading luggage such as air guide plates or sheets for reducing air resistance during traveling. Mounting holes are provided on the roof of such vehicles,
The air guide plate or the roof carrier is placed on the roof by bolting the mounting portion of the wind guide plate or the roof carrier to the mounting hole. In addition, such a vehicle is provided with an elevating ladder behind the side door on the side of the cab for taking or working on luggage or the like placed on the roof carrier, or in a fashion sense. .

As shown in FIGS. 5 (a) and 5 (b), the ladder 4 is mounted by mounting the upper part of the ladder 4 on the side of the cab 1 via a stay 4a. The stays 4a are fixed to both ends of a steel plate bent in a substantially U-shape, with respective columns 4b on both sides of the ladder 4,
The ladder 4 is attached to the cab 1 by bolting the middle of the stay 4a to the cab 1. On the other hand, a bed or the like for a driver to take a nap is provided behind the driver's seat inside the cab 1 such as a truck, and an auxiliary window 1b is generally provided behind the side door on the side surface of the cab 1. . The place where the stay 4a of the cab 1 is attached is generally located above the auxiliary window 1b.
There is provided a mounting hole for mounting. As shown in FIG. 4B, a nut 3 is previously fixed to the inner surface of the cab around the mounting hole via a reinforcing plate 2, and a stay 4a is mounted by screwing a bolt 5. .

[0004]

However, providing the mounting holes in advance increases the number of parts such as the nuts 3 and the reinforcing plates 2 to be fixed and increases the weight, and the mounting holes are not provided. There has been a problem that the mounting cost is increased due to the formation, the increase in the man-hour for fixing the nut 3, and the increase in the man-hour for managing the parts. In addition, when the ladder 4 is not provided, the mounting hole is usually closed by the plug. However, the presence of the mounting hole deteriorates the external appearance and may cause rust. Further, in order to dispose such a ladder 4, a space for mounting the stay 4a is conventionally required behind the side door. In recent years, a side door has not been provided in a bedless vehicle having a cab 1 without a nap bed. There is also a problem that a sufficient space cannot be secured in the rear cab 1 and the ladder 4 cannot be arranged.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a ladder to which a ladder is attached without providing a hole for attaching the ladder to a side surface of the cab, thereby preventing an increase in weight and improving the appearance, and allowing the ladder to be attached to the cab at low cost. A vehicle ladder mounting structure is provided. It is another object of the present invention to provide a vehicle ladder mounting structure that allows a ladder to be mounted even when there is not enough space in the cab behind the side door.
