PROBLEM TO BE SOLVED: To provide a bush cutter having a grass-winding prevention cup for preventing winding of trees and plants, or the like onto the end of a bush cutter, and for efficiently performing bush-cutting work by lightening a burden imposed on a worker.SOLUTION: The bush cutter includes: a rotary drive unit, such as an engine and a bearing unit connected to a rotating shaft of the rotary drive unit with a connecting rod, and having a rotary blade attached to the end of the connecting rod. In the bush cutter, the grass-winding prevention cup is formed in a cup shape from a sidewall having a nearly circular shape in a plan view and having a prescribed height and, a bottom wall including an opening having an internal diameter larger than an external diameter at the lower end of the outer peripheral surface of the bearing unit in the center portion, and is integrally stuck to the lower end of the outer peripheral surface of the bearing unit by fixing means while the side of an opposite rotating side is open without projecting to the side of the rotary blade from an attachment surface of a receiving flange of the bearing unit.COPYRIGHT: (C)2012,JPO&INPIT【課題】草木等の刈払い機先端への巻き付きを防止し、作業者への負担の軽減を図り刈払い作業を能率的に行うことが可能な巻付き防止カップ付き刈払い機を提供する。【解決手段】エンジン等の回転駆動部と、該回転駆動部の回転軸に連結杆で連結され該連結杆の先端に回転刃が取り付けられる軸受け部と、を備えた刈払い機であって、軸受け部の外周面下端に、平面視略円形の所定高さの側壁と、中心部分に軸受け部の外周面下端の外径より大きな内径の開口を有する底壁とでカップ形状に形成された巻付き防止カップを、固着手段により軸受け部の受けフランジの取付面より回転刃側に突出せず反回転刃側が開口した状態で一体的に固着したことを特徴とする。【選択図】図2
