摘要： A shock absorbing member is arranged at a side end portion of a vehicle, and is formed into a tubular shape extending in a vehicle front-and-rear direction. The shock absorbing member includes an outer wall portion formed so as to extend in a vehicle height direction and the vehicle front-and-rear direction, an inner wall portion formed so as to extend in the vehicle height direction and the vehicle front-and-rear direction, and arranged on a center portion side of the vehicle in a vehicle width direction with respect to the outer wall portion so as to be opposed to the outer wall portion, an upper wall portion connected to upper end portions of the inner wall portion and the outer wall portion, a lower wall portion connected to lower end portions of the inner wall portion and the outer wall portion, and a horizontal rib connected to the inner wall portion and the outer wall portion. A distance between the upper wall portion and the lower wall portion is decreased as approaching from the inner wall portion side to the outer wall portion side. A thickness of a part of the horizontal rib, which is connected to the outer wall portion, is set larger than a thickness of a part of the horizontal rib, which is connected to the inner wall portion.
