Abstract: Disclosed is an automatically foldable support stand for a golf bag. The support stand includes a pair of legs and a V-shaped elastic rod adapted to move the legs between spread position and retracted position according to the movement of a bag body between its tiled position and its upright position. A free end of the elastic rod is engaged with an engagement groove of a base plate. An elasticity enforcing part integrally formed to the base plate is engaged with the elastic rod thereby substantially shortening a coincidence point of the V-shaped elastic rod. A guide shoe attached at a lower position of the golf bag penetrates through a guide block which is vertically extended from the base plate whereby a movement of the base plate is guided along a path controlled by the guide shoe.
