Summary:PROBLEM TO BE SOLVED: To provide an electric lawn mower including a control device being easily cooled.SOLUTION: An electric lawn mower 1 comprises: a body 2 including a base part 2b that has a blade storage chamber 7 recessedly provided at a bottom part and downward opened, and a through-hole 32 vertically penetrating to the blade storage chamber, and a cover part 2c for covering the upper side of the base part from the upper side; a motor support plate 38 provided on an upper face of the base part and covered by the cover part from the upper side; an electric motor including an output shaft 64 projecting downward from the through-hole, supported by the motor support plate and covered by the cover part from the upper side; a blade 3 provided at the output shaft 64 and stored in the blade storage chamber; a control device 10 for controlling the electric motor; and an airflow passage A extending from an air inlet 21 provided at the body to the blade storage chamber. A control device support plate 80 for supporting the control device extends from the motor support plate to the air inlet. The airflow passage includes a space X delimited between the upper face of the base part and the lower face of the motor support plate.SELECTED DRAWING: Figure 2 【課題】 制御装置が冷却されやすい電動芝刈機を提供する。【解決手段】 電動芝刈機で1あって、底部に凹設され下方に向けて開口したブレード収容室7及び上下に貫通してブレード収容室に至る貫通孔32を有するベース部2b、及びベース部の上部を上方から覆うカバー部2cを備える本体2と、ベース部の上面に設けられ、カバー部によって上方から覆われたモータ支持板38と、貫通孔から下方に突出する出力軸64を有し、モータ支持板に支持され、カバー部によって上方から覆われた電気モータと、出力軸64に設けられ、ブレード収容室に収容されたブレード3と、電気モータを制御する制御装置10と、本体に設けられた空気取入口21からブレード収容室に至る空気流通路Aとを有し、制御装置を支持するための制御装置支持板80がモータ支持板から空気取入口に向かって延出し、空気流通路がベース部の上面とモータ支持板の下面との間に画定される空間Xを含む。【選択図】 図2
