It is composed of a structure that inserts and installs the second strut made of wood, which is a material of the material, for example, when the vehicle collides, the second strut made of wood withstands the momentum of the vehicle, and is damaged at some point and the momentum of the vehicle is damaged. This reduces the amount of impact transmitted back to the driver in the vehicle.

However, since the shock absorbing guard rail according to the prior art is configured to reduce the momentum of the vehicle only by a plurality of second struts itself breaking, the impact amount generated when the second strut is damaged to the driver. As it is transmitted as it is, it cannot effectively reduce the impact amount, and because a large amount of struts are damaged at the time of a vehicle crash, this causes a large portion of the guard rail to be damaged, which requires a lot of effort and additional cost to rebuild it. There is.
