Underframe and golf bag using the improved underframe

An improved underframe, connected to a bag body of a golf bag, for fitting a plurality of elastic rods and a supporting frame of the golf bag, comprising:

• a base plate, for support on the ground, a wall part, configured around the base plate, a first socket and two second sockets, configured at three positions on an inner side of the wall part, for insertion of one end of each of the elastic rods, specifically, the first socket is located on one side of the underframe away from the supporting frame, two sides of the first socket are provided with two slits, the two slits extend from a top side of the wall part to the base plate, so that the first socket, the wall part and the base plate between the two slits can move elastically,
• wherein the two sealing components are made of an elastic material other than that of the underframe.
