PROBLEM TO BE SOLVED: To allow the height of a blade to be readily and accurately verified in a lawnmower.SOLUTION: The lawnmower 10 is provided with a height adjusting mechanism 20, the height adjusting mechanism includes: a front wheel supporting member 21L and a rear wheel supporting member that are connected to the housing 11 so as to be capable of swinging up and down a linking member 25 for linking the front and rear wheel supporting members so as to be capable of associated motion and a locking mechanism for restricting and releasing displacement of the linking member in the forward and backward direction. The front wheel supporting member includes an arcuate part 81 having an arcuately shaped outer circumferential surface 81a centered on a center Pf of vertical swinging relative to the housing. The outer circumferential surface has a display part 83 for displaying the height of the blade, the outer circumferential surface being positioned further to the inside of the housing in the widthwise direction than an end. The housing has a peephole 84 for allowing the display part to be viewed.COPYRIGHT: (C)2012,JPO&INPIT【課題】芝刈機において、刈刃の高さを的確に且つ容易に確認できること。【解決手段】芝刈機10の高さ調整機構20は、ハウジング11に上下スイング可能に連結された前輪支持部材21L及び後輪支持部材と、前及び後輪支持部材同士を互いに連動可能に連結した連結部材25と、連結部材の前後方向の変位を規制及び解除するためのロック機構とからなる。前輪支持部材は、ハウジングに対する上下スイングの中心Pfを基準とした円弧状の外周面81aを有している円弧部81を備える。外周面は、ハウジングの幅方向の端よりも内側に位置し、刈刃の高さを表示するための表示部83を有する。ハウジングは、表示部を目視可能な覗き孔84を有する。【選択図】図19
