PROBLEM TO BE SOLVED: To provide a rubber plate, a hanging plate made of sheet metal or the like as a mode for preventing scattering of reaped items and stones and the like of a mower, but the rubber plate is inferior in durability and made of sheet metal. When the stone is bounced off, the stone easily opens widely, and the stone pebbles easily come out to the outside from the cover gap portion where the cover is opened. SOLUTION: A cover plate made of a sheet metal or a hard resin plate, which is divided into a plurality of sheets in a width direction and is formed into a row shape, at an inlet portion 7 or an outlet portion 8 of the cut grass of a reaping cover 5. A double structure in which 10 is oscillated back and forth, and an outer cover 12 formed of an elastic material such as a single plate-shaped or single sheet-shaped rubber material is hung along the outer surface of the cover plate 10. The cover K is provided. [Selection diagram] Figure 1【課題】草刈機の刈取物や、石礫等の飛散防止を行う形態として、ゴム板や、板金製の吊下板等を設ける形態があるが、ゴム板では耐久性が劣り、板金製では、石が跳ね出されるとき、容易に大きく開いて、このカバーの開かれるカバー間隔部から石礫が外部へ飛び出し易くなる。【解決手段】刈取カバー５の刈草の取入口部７、又は、排出口部８に、幅方向に亘って複数枚に分割し列状形態に形成した板金製、乃至硬質樹脂板製のカバー板１０を前後揺動自在に吊下し、このカバー板１０の外側面部に沿う、一枚板状、乃至一枚シート状のゴム材のごとき弾性材で形成の外カバー１２を吊下する二重カバーＫを設けた構成とする。【選択図】図１
