PROBLEM TO BE SOLVED: To provide a novel attaching structure for a pipe handle and a blade in an agricultural tool such as a hoe and a rake.SOLUTION: A blind-pipe-shaped pipe end member 2 which is molded of a high-strength synthetic resin material and whose diameter becomes larger toward the distal end is fixed to the distal end of the pipe handle by means of insert molding, etc. A cylindrical chest 4 formed in a part of the blade 3 such as a hoe plate is inserted and forcedly fitted from the proximal side of the pipe end member 2. The chest 4 is fixed by a pin 5 penetrating the chest 4, the pipe end member 2 and the pipe handle 1 with the chest 4 forcedly fitted to the pipe end member 2. The cross-sectional shape of the pipe end member 2 and the chest 4 is rectangular. The upper surfaces 2a and 4a, and right and left side surfaces 2b and 4b are formed as planes parallel to the axial direction of the pipe handle 1, and only the bottom surfaces 2c and 4c are formed as planes inclined in such a direction that the diameter becomes larger toward the distal end.COPYRIGHT: (C)2012,JPO&INPIT【課題】鍬や備中などの農工具における、パイプ柄と刃体の新規な取付構造を提供する。【解決手段】パイプ柄1の先端部分に、高強度の合成樹脂材で成型し、先方に向けて太径となる盲筒状の管端部材2を、インサート成型などで固着する。管端部材2の基方から、鍬板などの刃体3の一部に形成した筒状のヒツ4を挿入して無理嵌めし、管端部材2とヒツ4の無理嵌め状態において、ヒツ4と管端部材2及びパイプ柄1を貫通させるピン5によって固定する。管端部材2及びヒツ4の断面形状を方形とし、上面2a、4a及び左右の側面2b、4bをパイプ柄1の軸方向と平行な面で形成し、底面2c、4cのみを先方に向けて太径となる方向の傾斜面で形成することができる。【選択図】 図1
