PROBLEM TO BE SOLVED: To prevent spatter from being scattered to a screw hole of an anchor bracket when the anchor bracket is spot-welded to an anchor part of an automobile pillar. SOLUTION: In the anchor part structure of the automobile pillar, the anchor bracket 3 provided with a weld nut 4 forming the screw hole 40 concentric with a bolt through hole 10 is superposed on a back surface side around the bolt through hole 10 of an inner panel 1 of the pillar, both ends 31, 32 are spot-welded to the inner panel 1, and beads 33 of an approximately U shape cross section crossing the bracket 3 in a width direction are formed in an intermediate part of the spot-welded parts SP at both ends and the screw hole 40 on the bracket 3, respectively. Beads 11 of an approximately U shape in cross section superposed on the respective beads 33 of the bracket 3 are formed on the inner panel 1, and the spatter generated in welding is prevented from passing through a clearance between the inner panel 1 and the bracket 3 and scattering to the screw hole 40.
