A shock absorbing vehicle body structure in a vehicle includes a substantially quadrilateral front subsidiary frame comprised of left and right side members extending in a longitudinal direction of a vehicle body and connected at their front and rear ends to each other by a front cross member and a rear cross member. The front subsidiary frame is supported at its four corners on main frames for the vehicle body through rubber mounts and bolts. Upon full-lap collision of the vehicle, the left rear bolt is first broken, whereby the rear end of the left side member is separated from the main frame and then, the right rear bolt is broken, whereby the rear end of the right side member is separated from the main frame. The right and left side members are formed with different rigidities to a longitudinal load applied thereto, which causes the right and left rear bolts to break at different times, or with a time lag therebetween. Such a time lag decreases the peak value of deceleration of the vehicle at a time when the front subsidiary frame is separated from the main frames due to a full-lap collision of the vehicle.
