It rotates and its rotation angle is regulated by the chain member 23, so that the ladder unit 6 is inclined so as to form a constant angle with respect to the slide rail mechanism 13 extending in the horizontal direction. <Fourth stage> Then, as shown in FIG. 12, in a state where the application of the stopper pin member 38 is released, the movable leg 37 is slid by its own weight to pull out the anti-slip end tool 36 downward and the ladder unit 6 The whole is pressed against the vehicle body 1 side and locked by the lock mechanism 27. The lock by the lock mechanism 27 enables the upper portion of the ladder unit 6 to be easily locked to the vehicle body 1 with one touch, and can be easily attached and detached by one person. This attachment / detachment is also assisted by the positioning member 29. When unlocking by the lock mechanism 27, contrary to the case described above, by pulling the ladder unit 6 toward you, the lock of the lock mechanism 27 is easily released with one touch.

After that, the stopper pin member 38 is applied with the anti-slip end 36 in contact with the ground so that the movable leg 37 does not slide and the amount of protrusion does not change.
The non-slip end tool 36 and the movable leg 37 prevent the gap between the ladder unit 6 and the road surface and prevent rattling by keeping them in close contact with the road surface without being influenced by the condition of the road surface. It is possible to set the ladder unit 6 in a predetermined state without doing so. <Fifth Stage> After that, as shown in FIG.
1 is rotated by approximately 90 ° to be in an upright state, and as shown in FIGS. 14 and 15, the handrail member 31 is slid upward to engage the leg portion 31a with the engaged member 34 in a disengageable manner. Then, the locking means 35 is applied to complete the installation.

Further, when storing, the operation reverse to the operation described above may be performed.

As described above, in the ladder unit 6, when the handle 28 is grasped and pulled out, the hanger rail mechanism 12 has a full stroke, and further both rail members 20, 21 of the slide rail mechanism 13 move relatively. As a result, the inner rail member 21 is further pulled out with respect to the outer rail member 20, and the ladder unit 6 can be installed in a predetermined state by easily pulling the ladder unit 6 out of the vehicle, rotating it, and pressing it. Has become. Therefore, regardless of gender, it can be easily installed or stored by one person in a short time (within 1 minute).
