きくなるという欠点があった。(Problem to be Solved by the Invention) However, in the vehicle step mechanism having the above-mentioned configuration, the amount of protrusion of the step plate outside the vehicle is increased and the height from the ground is increased so that passengers can easily get on and off the vehicle. To make it lower, the link mechanism must be made longer. However, since the link mechanism rotates in the vertical direction of the vehicle, there is a drawback that the storage space becomes large when the step plate is stored in the lower part of the vehicle.

ッププレートが配置される。(Operation) The above technical means operates as follows. While the vehicle is running - the step plate is stored in the lower part of the vehicle parallel to the link mechanism. Even if the link mechanism is lengthened, the storage space can be minimized. Further, when the drive mechanism is activated while the vehicle is stopped, the link mechanism rotates in the longitudinal direction of the vehicle around the fixed portion to the step plate. As a result, the step plate protrudes outside the vehicle by the length of the link mechanism, and the height to the ground is also increased by the length from the fixed part of the link mechanism to the chassis frame to the fixed part of the link mechanism and step plate. Because it is lower, the step plate is placed in a position that makes it easier to get on and off.

によりステッププレート８は乗降者が乗降しやすい乗降
位置に配置されることになる。When the vehicle door (not shown) is closed in FIGS. 1 and 2, the motor 17 is not operating and the step plate 8 is housed in the lower part of the rocker panel 15. At this time, the link 4°5 is parallel to the step plate 8. When a passenger opens the door of the vehicle to get on or off the vehicle, the motor 17 is activated and the link 18 rotates clockwise. As a result, the link 19 is pulled in the direction C in the second diagram. For this reason, the links 4.5 each rotate clockwise about the axis 6.7, and the step plate 8 is moved around the rocker panel 15, as shown in FIGS. 3 and 4.
Protrude more outward. At this time, since the bracket 10.11 rotates clockwise about the axis 12.13, the step plate 8 rotates without always maintaining a position parallel to the rocker panel 15. Furthermore, since the rotation center 12.13 of the bracket 10.11 is located below the rotation center 6.7 of the link 4.5, the step plate 8 is
7 is located below the storage position when not in operation. As a result, the step plate 8 is placed at a position where passengers can easily get on and off the vehicle.

閉じるとモータ１７は再び作動し、リンク２１を押す。The motor 17 detects when the step plate 8 reaches a predetermined position, that is, when the link 19 is pulled to the maximum, and stops its operation. As a result, the step plate 8 is held at the getting on/off position. When the passenger finishes getting on and off the vehicle and closes the door of the vehicle, the motor 17 is activated again and pushes the link 21.

The motor 17 detects when the step plate 8 comes to the storage position, that is, when the link 19 is pushed to the maximum, and stops its operation. As a result, the step plate 8 is held in the storage position by the link 19.

ことはない。As mentioned above, the step plate 8 is connected to the rocker panel 1.
When the link 4.5 is stored in the lower part of the step plate 8, the link 4.5 becomes parallel to the step plate 8. Therefore, in order to keep the step plate 8 at a low position and to increase the protrusion amount, the link 4.5 is placed in the lower part of the step plate 8.
Even if the length of 5 is increased, it can be stored in a high position with minimum storage space. In addition, since the motor box 16 and the link 4.5 are held by one bracket 2, they can be easily assembled to the chassis frame, and furthermore, since the assembly is carried out in good weather, the operation of the step mechanism is affected. Never.
