The reinforcement member includes a fan shaped longitudinal wall portion, and a bottom wall portion from which the longitudinal wall portion protrudes out, and the bottom wall portion joins one end portion and another end portion of an arc of the longitudinal wall portion that are oriented in a row along a length direction of the frame member to an inner face of a wall portion at a compression deformation side of the frame member that undergoes bending deformation due to the front side member being input with load. |
