Golf bag constituted by an upper end shield connected to a lower end shield by means of a peripheral cover and comprising a support incorporating two props, the upper end of each being jointed to the bag around a respective axis so as to rotate between two positions, i.e., a retracted resting position and a an extended position, these props being stressed into their retracted resting position by an elastic system constituted by an elastic U-shaped stirrup piece comprising two arms which extend upward and whose free ends are fastened to the props by a joint, and in which the end of the lower central part constitutes the device activating the support. The activation device is positioned in the half-space located above the plane formed by the support surface of the bottom of the bag, and extends outward away from the peripheral cover of the bag, so as to lie outside of the plane containing the two arms and at a distance from the point of support of the bag when the latter is in the inclined position.
