Moreover, the corner | angular part 50 and the hook part 70 may be abbreviate | omitted. For example, the fitting protrusion 46 may be formed in a cylindrical shape, and the fitting hole 52 may be formed in a circular hole.

  As shown in FIG. 5, in the above embodiment, the main body portion 54 in which the fitting hole 52 is formed is configured to be separated from the support portion 56, but the main body portion 54 and the support portion 56 are integrally formed. It may be configured.

  As shown in FIG. 1, in the said embodiment, although the fence 10 is comprised cyclically | annularly using the six fence panels 12, the number of the fence panels 12 may be made into 3-5 sheets, It may be 7 or more. Further, the fence may be configured in a wall shape in which both end portions in the width direction are opened. In this case, the number of the fence panels 12 may be two. Furthermore, the length in the width direction of each of the plurality of fence panels 12 may be different.

  However, in order to fold the fence configured in an annular shape, it may include four or more even number of fence panels 12 and the same number of fence connection structures 14 that connect these fence panels 12 in an annular shape. desirable. Moreover, it is desirable that the lengths in the width direction of the plurality of fence panels 12 are the same. For example, if the number of fence panels is 8, four fence panels 12 may be folded and overlapped in a W shape, and the remaining four fence panels 12 may be folded and overlapped in a W shape. it can. If the number of fence panels is four, the two fence panels 12 may be folded and overlapped in a V shape, and the remaining two fence panels 12 may be folded and overlapped in a V shape. it can.

  FIG. 8 is a front view showing a modified example of the support column. As shown in FIG. 4, in the above embodiment, the vertical lengths of the support portion 48 of the first fitted portion 42 and the support portion 56 of the second fitted portion 44 are shortened. As shown, the vertical lengths of the support 48 and the support 56 may be made longer. In this case, since the support | pillar part 38 can be reinforced with the support part 48 and the support part 56, durability of the connection structure for fences can be improved. Further, in this case, the gap between each of the first fence panel 12a and the second fence panel 12b shown in FIG. 4 and the column part 38 can be filled with the support part 48 and the support part 56. It is possible to prevent objects from entering the door.
