In this embodiment, the wire 23 and the planting base 15 function as a plant support member that supports the vine plant 25. The wire 23 corresponds to a first support part that supports the vine of the vine plant 25, and the planting base 15 corresponds to a second support part that supports the root of the vine plant.

  In the present embodiment, the upper and lower ends of each protection plate (21, 22) are fixed to the lower frame 33 and the upper frame 34, respectively. In the present embodiment, the first and second protection plates 21 and 22 have a portion in which two sheets are continuously arranged so as to be asymmetric with respect to the wire 23 when viewed from above.
