However, in the case of the above conventional structure, the display member is arranged in a horizontal position across the roadway when the traffic restriction is displayed, and the display member is arranged in the upright and rotated upright position and retreats from the roadway when the non-restriction is displayed. However, since the display member is placed in an upright position instead of a horizontal position when the display is not restricted, there is a risk that the display member will be damaged by a large external force due to strong winds or snowstorms. If the projection length from the position to the horizontal position that crosses the roadway is relatively short, it becomes difficult for the driver to accurately visually recognize whether the display member is in the horizontal position or the upright position. It has the disadvantage of lowering

An object of the present invention is to solve such inconveniences. A vehicle travel regulation display device comprising a display member horizontally projecting from a lateral position in a direction crossing the roadway to guide and regulate the travel direction of the vehicle, the device being installed at the lateral position of the roadway. a body, a holding member capable of holding the display member, a connecting mechanism capable of connecting the holding member to the device body, and the holding member between a horizontal position crossing the roadway and a standing position, or the It comprises a raising/lowering/rotating mechanism for raising/lowering between a standing position and a storage position on the side of the roadway, and a horizontal turning mechanism for horizontally turning the holding member in the standing position. The travel regulation display device for a vehicle is characterized in that it is provided so as to be freely tiltable and swivel between the horizontal position and the retracted position via an upright position.

Further, the invention according to claim 2 is characterized in that the display member has an arrow display structure. The invention according to claim 3 is characterized in that an overload of a predetermined value or more is applied to the holding member. A torque limiter is provided to allow the holding member to turn when the holding member is turned. A fifth aspect of the invention is characterized in that the horizontal turning mechanism comprises a horizontal turning motor and a worm reduction mechanism.

Further, according to the sixth aspect of the invention, the connecting mechanism is constructed so as to be capable of selectively connecting a plurality of holding members having different projecting lengths from the lateral position of the roadway to the horizontal position crossing the roadway. It is characterized by

As described above, according to the invention of claim 1, the display member is arranged at a horizontal position across the roadway when driving restriction is displayed during road construction or the like, and the driving restriction is visually recognized by the driver through the display member. At the time of non-restriction display at the end of road construction, etc., the holding member is raised and rotated from the horizontal position crossing the roadway to the standing position by the raising and lowering rotation mechanism, and is rotated by the horizontal rotation mechanism. The holding member is horizontally rotated from the upright position to the side position of the roadway, and then tilted from the upright position to the storage position on the side of the roadway. The mechanism rotates the holding member from the stored position on the side of the roadway to the upright position, and the horizontal turning mechanism horizontally turns the holding member from the upright position toward the roadway. Therefore, the holding member is moved to the horizontal position during the travel restriction display and during the non-restriction display through the upright position by cooperation of the raising and lowering rotation mechanism and the horizontal rotation mechanism. The display member can be tilted and turned between the storage positions, and the display member can easily perform the switching operation between the travel restriction display by the display member and the non-restriction display by retracting the display member, and when the non-restriction display is performed is retracted and stored from the horizontal position to the storage position via the standing position, and the display member is stored in a low storage position on the side of the roadway, for example, there is a risk that the display member will be damaged by strong external force due to strong wind or snowstorm. Alternatively, the display member in the retracted position during non-restriction display can be excluded from the driver's visual range as much as possible, so that the driver can accurately visually recognize the display member during travel restriction display. It is possible to improve the driving regulation display function.

Further, in the second aspect of the present invention, since the display member has an arrow display structure, it is possible to obtain a vehicle travel restriction display and guidance display, and to reliably display the travel restriction. In the third aspect of the invention, when an overload of a predetermined value or more is applied to the holding member, a torque limiter is provided to allow the holding member to turn. When an overload of a specified value or more is applied due to a collision or other external force, the holding member can be allowed to turn to prevent damage to the holding member and other mechanisms. In this case, the raising/lowering/rotating mechanism consists of a raising/lowering motor and a worm deceleration mechanism, so that the structure of the raising/lowering/rotating mechanism can be simplified. Since the horizontal turning mechanism comprises a horizontal turning motor and a worm reduction mechanism, the structure of the horizontal turning mechanism can be simplified.

In the sixth aspect of the present invention, the connecting mechanism is configured to selectively connect a plurality of holding members having different projecting lengths from the lateral position of the roadway to the horizontal position crossing the roadway. Therefore, by sequentially arranging a plurality of vehicle travel restriction display devices having holding members with different projecting lengths along the running direction of the roadway, it is possible to display, for example, the travel restriction of the vehicle. It is possible to display guidance to gradually change the course of the vehicle from the overtaking lane and driving lane of the roadway to the exit lane, or from the overtaking lane in which the vehicle is traveling to the adjacent driving lane, and the driving regulation display function. It can be improved further.
