PROBLEM TO BE SOLVED: To provide a vehicular seat sliding apparatus which can be molded with higher accuracy to keep the cross-section shape of a rail constant without reducing flexibility in designing seat surfaces.SOLUTION: At front ends of a lower rail 3, seat surfaces 71 are formed deviating from a first connection wall part 12 in the erecting direction of the lower rail 3 to support heads 76a of fastening bolts 76. A connection part 72 connecting each seat surface 71 and the first connection wall part 12 on the further counter end side of the lower rail 3 than the seat surface 71, is molded to have a plurality of ridge lines L1-L3 radially extending to intersect one another at one point (a starting point Ps) located on the further counter end side of the lower rail 3 than the seat surface 71. |
