PROBLEM TO BE SOLVED: To attain a vehicle body lower part structure capable of strengthening support rigidity for making a vehicle body support a center bearing of a propeller shaft, in particular, fore-and-aft support rigidity, and performing supporting by a common structure regardless of the propeller shaft in which an installation position of the center bearing is different. SOLUTION: In the vehicle body lower part structure, the center bearing 50 in the fore-and-aft midway of the propeller shaft 5 extending in a fore-and-aft direction along a lower surface of the vehicle body is supported on a bearing bracket 4 projectedly provided on the lower surface 1 of the vehicle body. Two fore-and-aft cross members 3a, 3b extending in a vehicle width direction are provided on the lower surface 1 of the vehicle body with an interval in the fore-and-aft direction, and a vertical member 6 extending in the fore-and-aft direction along the lower surface 1 of the vehicle body is laid between both cross members 3a, 3b. The bearing bracket 4 is installed on a fore-and-aft position in the vertical member 6 according to the installation position of the center bearing 50 in the propeller shaft 5, and the propeller shaft 5 is supported by the bearing bracket 4.
