A rear body structure of a vehicle body has a crushable reinforcement disposed inside a rear fender panel and extending in a lengthwise direction for structurally reinforcing a rear body portion of the vertical body. The crushable reinforcement is controlled so as to crush in an intended pattern during a rear-end collision. Consequently, the impact energy generated during the rear-end collision and applied to the automotive vehicle body is absorbed.
