  "textContent": "In a joining method for members, a tube body having a center axis L, a wall surface body having a hole portion through which the tube body can be inserted, and an elastic body that can be inserted in the tube body are prepared. The tube body has an inner rib extending in a direction of the center axis so as to partition an inside thereof, and the inner rib has notches cut from a lower end of the inner rib in the direction of the center axis. Next, the tube body is inserted through the hole portion in the wall surface body, and the elastic body is inserted into internal spaces partitioned by the inner rib of the tube body. Furthermore, the elastic body is compressed in the direction of the center axis of the tube body and expanded outward in a radial direction with respect to the center axis, whereby an end of the tube body is expanded and deformed to be joined to the wall surface body by press-fitting.",
