Claims (1)

[Claims for Utility Model Registration] 1. An attention display member, an attitude detection sensor attached to the attention display member, and an attitude detection sensor attached to the attention display member, which are provided in a spaced apart position, and where the attitude detection sensor and the and a warning generating means connected to the vehicle, and the warning generating means issues a warning upon receiving a signal output from the posture detection sensor indicating that the caution display member has changed its posture. An alarm device characterized by: 2. The alarm device according to claim 1, wherein a plurality of warning display members are connected in series. 3. Once the alarm generation means starts operating, the alarm generation means is equipped with a latch circuit that allows the alarm generation means to continue emitting the alarm even if the attitude detection sensor no longer outputs a signal indicating that the attention display member has changed its attitude. The alarm device according to claim 1 or 2, wherein the alarm device is provided with: 4. The alarm device according to any one of claims 1 to 3, further comprising a disconnection detection means for detecting a disconnection state of an electric wire connecting the attitude detection sensor and the alarm generation means. 5. The alarm device according to any one of claims 1 to 4, wherein the alarm generating means is constituted by an audio alarm means such as an automobile horn, a whistle, or a speaker. 6. The alarm device according to any one of claims 1 to 4, wherein the alarm generating means is constituted by a light emitting alarm means such as a rotating light or a flashing light. 7. Alarm generation means include audio alarm means such as a car horn, whistle or speaker, and revolving lights;
5. The alarm device according to claim 1, wherein the alarm device is configured in combination with a light emitting alarm means such as a flashing light. 8. The alarm device according to any one of claims 1 to 7, wherein the attention display member and the alarm generating means are separated by at least 10 m. 9. The warning device according to any one of claims 1 to 8, wherein the caution display member is a cone-shaped or rod-shaped member installed on the road. 10. The alarm device according to claim 1, wherein the attention display member is a swinging rod whose one end is swingably attached to a fixed member. 11. The alarm device according to any one of claims 1 to 9, wherein the attention display member is an arrow board. 12 An attention display member, a posture detection sensor attached to the attention display member, a transmitting means attached to the attention display member and transmitting an output signal from the attitude detection sensor wirelessly, Provided at a location separate from the alert display member,
A receiving means for receiving an output signal from the transmitting means, and an alarm generating means connected to the receiving means are provided, and the alarm generating means is configured to detect whether the alert display member output from the attitude detection sensor is in its attitude. An alarm device characterized in that the receiving means issues an alarm when the receiving means receives a signal indicating that the change has been made. 13. The alarm device according to claim 12, wherein the warning display member is equipped with a battery. 14. The alarm device according to claim 12 or 13, wherein the warning display member is equipped with a solar cell and a storage battery. 15 Once the alarm generation means starts operating, the alarm generation means is equipped with a latch circuit for continuing to issue the alarm even if the attitude detection sensor no longer outputs a signal indicating that the attention display member has changed its attitude. Claims 12 to 1 are provided with:
4. The alarm device according to any one of 4. 16 A plurality of warning display members, a detection member mounted between the warning display members, and an alarm generating means connected to the detection member,
