The present invention relates to a road shock alleviation apparatus that is installed in a deviation prevention apparatus such as a median strip and a guard rail which are installed on a road for vehicle lane deviation prevention and vehicle protection. The present invention includes a guard frame that is provided with multiple plate-shaped supporting members, the supporting members being pivotally coupled based on coupling members which are vertically inserted into through-holes formed in facing end portions and the supporting member coupled with a central portion protruding toward a road surface so that an accommodation space is formed therein; a shock alleviation member that is formed to be coupled in close contact with an inner surface of the guard frame; a guide member that is formed to include a guide groove which is formed in a longitudinal direction therein and an oscillation member which is formed to be inserted into the guide groove and slide; and a fixing member that is formed for the supporting members which are coupled with outermost sides on both sides of the guard frame to be coupled and interwork with the oscillation member.
