PURPOSE: A side reinforcing structure of a vehicle is provided to reduce the weight of a vehicle and the manufacturing cost and to reduce injury of a passenger to a minimum by protecting the abdomen of the passenger. CONSTITUTION: An impact beam is installed inside a door longitudinally to be able to protect the abdomen of a passenger. A fixed bracket(5) is installed in the middle of the impact beam to the same height as the abdomen of the passenger. The fixed bracket comprises a semicircular weld zone(5a) welded to the impact beam, a protruded part(5b) extended downward from the weld zone, and a flange part(5c) joined to the door by a seal. The protruded part is distorted in a side clash, and the external impact energy is reduced. Therefore, the abdomen of the passenger is protected, and the extent of injury of the passenger is reduced to a minimum.
