PROBLEM TO BE SOLVED: To obtain strut structure for pots, which is readily unfolded, stabilized in a unfolded state and has further reduced bulk volume when folded. SOLUTION: A first connection piece 16a to a first connection piece 16d are fixed to each tip of four struts 13a-13d constituting strut structure 11 of a pot and the pieces are rotatably connected by a first connection rod 15a to a first connection rod 15d. Similarly, a second connection piece 19a to a second connection piece 19d and a third connection piece 22a to a third connection piece 22d are fixed at the middle positions and the lower positions of the strut 13a to the strut 13d. A second connection rod 18a to a second connection rod 18d and a third connection rod 21a to a third connection rod 21d are each rotatably fixed to each of the connection pieces. Consequently, when pairs of the struts facing each other are mutually moved in the opposite directions, the whole struts are folded in a bar state.
