A walk-behind lawnmower having a rear shield (40) is disclosed. The rear shield (40) extends downward from a rear end part (11a) of a housing (11) and is in the form of an elastic sheet. The sheet (40) has a thin-walled part (49) formed in a central site (48) in a heightwise direction between an upper end part (41) and a lower end part (42), the upper end part being attached to the rear end part of the housing. The thin-walled part has a thickness (t2) set to be smaller than a thickness (t1) of other parts (47a, 47b).本發明揭示一種具有一後部屏障(40)之後推式割草機。該後部屏障(40)自一外殼(11)之一後端部分(11a)向下延伸,且呈一彈性薄片之形式。該薄片(40)具有一形成於在一上部端部分(41)與一下部端部分(42)之間的一高度方向上之一中央位點(48)中的薄壁部分(49),該上部端部分附接至該外殼之該後端部分。該薄壁部分具有一經設定為比其他部分(47a、47b)之一厚度(t1)小的厚度(t2)。10...後推式割草機11...外殼11a...外殼之後端部分11b...左及右側向壁13...左後輪、右後輪21...左及右後輪支撐板23...輪軸24...連桿25...臂連結銷26...彈簧釘銷27...實質上水平連桿臂28...彈簧31...變速驅動器32...傳動軸40...後部屏障41...上部端部分42...下部端部分43...前部薄片表面44...後部薄片表面45...受支撐部分46...垂直板形肋狀物47a...平板區域之其他部分47b...平板區域之其他部分48...中央位點49...薄壁部分51...突出部分61...水平支撐銷Af...箭頭Ar...箭頭La...草地Pr...旋轉中心Qr...由假想線展示之位置
