PROBLEM TO BE SOLVED: To provide a walking type lawn mower which can adjust the mowing height by a simple operation.SOLUTION: In the walking type lawn mower, a transmission case 5 capable of being freely swung on a swinging axis X of laterally horizontal posture as a center is supported in a housing A. A mowing blade driven on a vertical driving axis Y as a center is disposed at the lower end of the transmission case 5, and a mowing height-adjusting mechanism E swung on the swinging axis X of the transmission case 5 as the center to adjust the mowing height is also disposed. In the mowing height-adjusting mechanism E, a control member 73 is swung on a shaft 72 as the center by the operation of an adjusting lever 74 to guide a control pin 76 to one of different opening widths of the single control opening 73C of the control member 73. The control pin 76 is supported on the transmission case 5, and the movement of the control pin 76 is controlled with the control opening 73C, thereby setting the swinging quantity of the transmission case 5 to set a mowing height.COPYRIGHT: (C)2011,JPO&INPIT【課題】簡便な操作により刈高さの調節が可能な歩行型草刈機を構成する。【解決手段】ハウジングAに対し、左右向き水平姿勢の揺動軸芯Xを中心として揺動自在に伝動ケース5を支持し、この伝動ケース5の下端に縦向きの駆動軸芯Yを中心として駆動される刈刃を備え、伝動ケース5の揺動軸芯Xを中心とした揺動により刈高さを調節する刈高さ調節機構Eを備えた。この刈高さ調節機構Eが、調節レバー74の操作でシャフト72を中心にして規制部材73を揺動させることで、この規制部材73の単一の規制開口73Cの異なる開口幅の何れかに規制ピン76を導入する。規制ピン76は伝動ケース5に支持され、規制ピン76の移動が規制開口73Cによって規制されることにより、伝動ケース5の揺動量を設定して刈高さを設定する。【選択図】図8
