The jersey net 2 may be made of a woven polyester fiber or vinylidene chloride resin fiber, and the holding member 4 may be a flexible and elastic resin tube. The resin tube is preferably made of a material obtained by mixing vinyl chloride and rubber.

The jersey net 2 has an edge 20 woven on the back surface of the baffle plate 1. The edge 20 is pressed into the groove 10 formed around the back surface of the baffle plate 1 together with the pressing member 4 and fixed. Have been.

FIG. 2 is a perspective view showing the baffle plate 1 before the jersey net 2 is attached. The groove 10 has a shape passing from one end to the other end of the baffle plate 1 so that a cutting tool can be inserted from one end and linearly moved to the other end for cutting. That is, the groove portions 10a, 10b, 1
The grooves 10 connected to the entire periphery of the back surface of the baffle plate 1 are formed by processing the holes 0c and 10d. Thus, from the viewpoint of ease of processing, the four groove portions 10
Since the groove 10 is formed by a to 10d, it is not limited to this shape, and it is also possible to perform processing so that the end of the groove 10 does not protrude from the end surface of the baffle plate 1.

FIG. 3 is a sectional perspective view of the holding member 4.
A plurality of ridges extending in the length direction of the holding member 4, that is, triangular teeth are formed on the outer periphery of the holding member 4 in order to prevent slippage with the jersey net 2.
The central portion is in the shape of a tube provided with a hole 40, but may be solid. Further, the unevenness formed on the outer shape is not limited to a triangular tooth shape, and may be any shape as long as it prevents slippage with the jersey net 2. For example, the pressing member 4 may have a round bar shape in which unevenness is omitted by increasing the surface friction coefficient by increasing the rubber component, for example, depending on the material or surface treatment of the pressing member 4.

FIG. 4 is a sectional view taken along the line AA of FIG. The jersey net 2 is pushed into the groove 10 of the baffle plate 1 together with the holding member 4, and is fixed to the baffle plate 1 by the repulsive force caused by the compression deformation of the holding member 4. In particular, no slack occurs on the surface side of the baffle plate 1.
Since the pressing member 4 is in contact with almost the entire periphery of the edge 20 of the jersey net 2, a uniform tension state is maintained over the entire periphery of the baffle plate 1. Further, after the holding member 4 is pushed in, the triangular tooth portion is further pushed with a claw and the arrow C is pressed.
By rotating the jersey net 2 in one direction or the C2 direction, the strength of the jersey net 2 can be adjusted.
