The plane portion 41 has a through hole 41a that penetrates vertically. As shown in FIG. 8, a bolt 43 serving as a threaded portion is passed from below the through hole 41a and is screwed into the threaded hole 28a of the mounting portion 28 of the receiving member 21. Thereby, the base member 40 is fixed to the receiving member 21. When fixing the base member 40 to the two receiving members 21 of the fence main body 10, as shown in FIG. 3, if the longitudinal direction of the flat part 41 of the base member 40 is arranged in the front-back direction, The fence main body 10 can be erected in a more stable state. Therefore, it is not necessary to erect a post on the installation surface and attach the fence main body 10 to the post, which is a common method of installing a fence, so the fence 100 can be installed at any location.

10 and 11 are explanatory diagrams showing a modification of the fence 100 shown in FIG. 1, in which FIG. 10 is a front view and FIG. 11 is a sectional view taken along the line BB in FIG. 10. The fence 100 according to the present embodiment is further provided with retaining posts. Specifically, diagonal members 44 are used as braces connected to the upper end of the fence main body 10 and the plane portion 41 of the base member 40. Thereby, even if a passerby comes into contact with the fence body 10 when passing in front of the fence 100, the fence body 10 will not easily fall down. The bolt 43 of the base member 40 is inserted into a through hole 41b formed on the front side of the through hole 41a into which the bolt 43 is inserted in FIG. ) is screwed into the Thereby, the planar portion 41 of the base member 40 is prevented from protruding on the front side with respect to the fence main body 10.
