PROBLEM TO BE SOLVED: To provide a lawn mower which prevents direct winding of grass on the revolving shaft of a rotary blade even when long grass is mowed in the time of grass mowing operation, slightly applies a load to the body of the lawn mower, and in which the grass is simply removed even when the grass is wound on the revolving shaft.SOLUTION: In the lawn mower 1 that has a handle 3 extended obliquely backward on the body 2, holds the handle 3 and performs grass mowing by grinding between the rotary blade 11 that interlocks a motor 7 mounted in the body 2 and rotates and a fixed blade 12 adjustably attached to the body 2, spacers 22 having an inner diameter larger than the revolving shaft 13 of the rotary blade 11 and an outer diameter smaller than a mowing diameter of the rotary blade 11 are installed between support parts (a) 20 and (b) 21 of bearings (a) 18 and (b) 19 pressed in both sides of the revolving shaft 13 of the rotary blade 11 and both end plates 15 and 17 for holding the blade part 14 of the rotary blade 11.COPYRIGHT: (C)2013,JPO&INPIT【課題】芝刈込み作業時、長い芝を刈込んだ場合でも回転刃の回転軸に芝が直接巻付くのを防止すると共に、芝が巻付いた場合でも芝刈機の本体に負荷を掛けることが少なく、しかも簡単に芝を取除くことが出来る芝刈機を提供することである。【解決手段】解決手段は、本体2の斜め後方に伸びたハンドル3を有し、該ハンドル3を保持して本体2内部に備えたモータ7に連動して回転する回転刃11と本体2に調整可能に取付けられた固定刃12の摺り合わせによって芝の刈込みを行う芝刈機1において、内径は回転刃11の回転軸13よりも大きく、外径は回転刃11の刈込み径より小さく形成されたスペーサ22を該回転刃11の回転軸13の両側に圧入された軸受(a)18、(b)19を支持部(a)20、(b)21と回転刃11の刃物部14を保持する両端のプレート15、17との間に取付けられるようにした。【選択図】図1
