Abstract: A shock absorbing member is supported on a shock absorbing member support bracket fixed onto a floor tunnel sandwiched between left and right front seats. Therefore, it is possible to allow the front seats to interfere with the shock absorbing member so that the member can absorb collision energy at a time of a side collision of a vehicle. Because a lower portion of a front wall connected to an inverted-U-shaped inner face of the shock absorbing member is connected to an upper portion of a front wall of the shock absorbing member support bracket, the front wall of the shock absorbing member support bracket receives a load of the side collision in a shearing direction. Accordingly, it is possible to increase strength of the front wall of the shock absorbing member support bracket against the side collision, prevent the shock absorbing member from falling down sideways, and enhance the shock absorbing effect.
