Abstract: A golf bag with a base having protrusion forming regions at a first section ranging from 30 to 60 degrees from a reference line, a second section ranging from 120 to 150 degrees from the reference line, a third section ranging from 210 to 240 degrees from the reference line, and a fourth section ranging from 300 to 330 degrees from the reference line. At each of the protrusion forming regions, one or more protrusions are formed to prevent the golf bag from rotating and falling over. A pair of tangents drawn from two of the protrusions in the front-rear direction and a pair of tangents drawn from two of the protrusions in the lateral direction pass outside of a base peripheral edge. Auxiliary protrusions may also be formed on the base at the positions of 90 degrees and 270 degrees from the reference line. All tangents linking the adjacent protrusions and all tangents linking the adjacent protrusion and auxiliary protrusion may pass outside of the base peripheral edge.
