<p>PROBLEM TO BE SOLVED: To provide a vehicle body lower part structure capable of improving NV performance.SOLUTION: A toe board part 18 has a support member 48 by comprising a fastening wall 52 for coupling a front suspension member 36. A construction member 60 is provided so as to cross a joint point of the fastening wall 52 and a floor panel 20 in a vehicle longitudinal direction and the construction member 60 is jointed to the fastening wall 52 and the floor panel 20. The construction member 60 is jointed to the fastening wall 52 for improving surface rigidity of the fastening wall 52, and deformation of the fastening wall 52 of the support member 48 for accepting input from the front suspension member 36 can be suppressed. Therefore, vibration of the fastening wall 52 when exciting force of a lower arm is inputted via the front suspension member 36 can be suppressed, and high NV performance can be secured.</p> |
