[0029]

As described above, the present invention has the following effects. Two rotary shafts extending in the vehicle width direction are provided at front and rear positions along a side surface of the vehicle placed at a predetermined position on the traveling carriage, and one end of an arm member is attached to each rotary shaft. By connecting the sub arm member to one of the arms so as to be interlockable with the arm member,
The range in which the arm member can reach is widened, and the effect can be exerted even on a high roof vehicle, which has not been conventionally prevented from opening the door. Further, since the sub arm member operates in response to the movement of the arm member, the driving means for the sub arm member can be omitted.

One end of the sub arm member is pivotally attached to the rotating shaft, and the arm member and the sub arm member are connected by a connecting member so as to form a V shape, and the connecting member is connected via a rotary joint. When two links are provided and one end of each link is rotatably connected to the arm member, the reach of the arm member is widened, and it is possible to cope with vehicles of various shapes.
Further, since the joint portions are folded and overlapped in parallel and stored in a small size, a large storage space is not required near the storage portion of the arm member, and the space on the carriage can be effectively used.

The rotary shafts have independent driving means, and when the arm members attached to the rotary shafts rotate in opposite directions, the rotation range of each arm can be set separately. Therefore, it is possible to cover a wider range of doors when the arm member is upright and to store the door between the front conveyor and the rear conveyor when storing. Further, since the dog is rotatably provided on the front rotary shaft and the rear rotary shaft and fixed at an arbitrary angle, the rotary angle of the arm member can be freely set. Easy to adjust after setting.

If the main arm member, the sub arm member, and the rear arm member are attached to the respective separate rotary shafts,
The structure of the arm member is simple because no connecting member is required. Since the doors can be prevented from being opened in a vehicle having any door arrangement with the rotation angles of the respective arm members being constant, it is not necessary to control the rotation angles of the arm members in a complicated manner.
