A
Abstract:
To provide a magnetic marker that is highly likely to maintain its function even when pavement is damaged.SOLUTION: A magnetic marker 1 disposed on a road 3 for use in driving support of a vehicle is a columnar magnet that has a shape where the uniformity of stress in response to an external force is impaired and stress is concentrated at a location, and is easy to break and separate into multiple small pieces due to concentration of stress. When pavement damage occurs around magnetic marker 1, by separating some of the small pieces, there is a possibility that some of the remaining pieces will remain on the road side and maintain magnetic performance.SELECTED DRAWING: Figure 1
