[Embodiment]
The lock mechanism 30 of the opening / closing member 20 and the netted sash 1 provided with the lock mechanism 30 will be described with reference to FIGS. 1 to 5. FIG. 1 is a perspective view of the net body 2 before being bent with the edge reinforcing portion 6 as a boundary. FIG. 2 is a perspective view of the net body 2 in a state of being bent with the edge reinforcing portion 6 as a boundary. FIG. 3 is a perspective view of the sash 4. FIG. 4 is a perspective view of the sash 1 with a mesh according to the embodiment. FIG. 5 is an enlarged view of the edge reinforcing portion 6 and the net portion 5 in the net body 2.

As shown in FIG. 1, the net body 2 has a net portion 5 and an edge reinforcing portion 6. The net unit 5 is a sheet woven into a mesh shape. The net unit 5 has a substantially rectangular shape having four sides. A specific example of the net unit 5 is, for example, an 18 mesh having an individual gap size of 1.4 mm × 1.4 mm. The net body 2 is, for example, an insect repellent net.

As shown in FIG. 5, the edge reinforcing portion 6 is reinforced by a tape-shaped reinforcing member attached to each side of the net portion 5. The edge reinforcing portion 6 is a portion fixed by the opening / closing member 20 of the sash 4, which will be described later. The edge reinforcing portion 6 is provided at the peripheral end portion of the net body 2 excluding the corner portion.

The reinforcing member of the edge reinforcing portion 6 is a resin tape having higher rigidity than the net portion 5 of the net body 2, and is, for example, polyester.
