PROBLEM TO BE SOLVED: To provide a self-propelled mower enabling a power supply terminal of a charging base and a power receipt terminal of a mower body to contact each other reliably by enhancing tolerance of a posture of a mower body when docking to the charging base.SOLUTION: A charging base 50 includes two power supply terminals 57, 58 rotatable in an approach direction of a mower body 10. The two power supply terminals are arranged while separated from each other at a distance and include rotation members 55a, 55b arranged in a direction approaching each other and extended in a peripheral direction and energized in an opposite direction to the approach direction of the mower body with respect to a rotation shaft. A power receipt part 41 in a protrusion shape is formed at a tip of a chassis of the mower body and power receipt terminals 42, 43 are arranged on both side faces of the power receipt part. When the mower body approaches the charging base and the power receipt part in the protrusion shape enters between the two power supply terminals, charging is performed by contact of the power supply terminals and the power receipt terminals.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2017,JPO&INPIT【課題】草刈機本体の充電ベースへのドッキング時の姿勢の許容度を上げて、充電ベースの送電端子と草刈機本体の受電端子を確実に接触させるようにした自走式草刈機を提供する。【解決手段】充電ベース50には、草刈機本体(10)の接近方向に回動可能な2つの送電端子57、58が設けられる。2つの送電端子は距離を隔てて配置され、お互い接近する方向に回動部材55a、55bからそれぞれ周方向に伸びるようにし、回転軸に対しては草刈機本体の接近方向とは反対方向に付勢される。草刈機本体のシャーシの先端には凸状の受電部41が形成され、受電部の両側側面に受電端子42,43が設けられる。草刈機本体が充電ベースに接近し、凸状の受電部が2つの送電端子の間に入り込むと送電端子と受電端子が接触することにより充電が行われる。【選択図】図9
