PURPOSE: A spacer grid for a fuel rod is provided to minimize the relative movement between the fuel rod and an inner grid plate by vertically moving an elastic support plate which supports the fuel rod. CONSTITUTION: A dimple supporting a fuel rod(50) is consecutively formed on one side of an inner grid plate(2). The inner grid plate includes a first inner grid plate(10) and a second inner grid plate(20). The first inner grid plate is orthogonally combined with the second inner grid plate. An elastic support plate is inserted into the inner grid plate. An outer grid plate(40) covers the inner grid plate.
