PROBLEM TO BE SOLVED: To provide an implement capable of switching a storage state and a working state, and having a high durability in a connection part and stable revolution turning operation of an elongated workplace.SOLUTION: An implement comprises: a first workplace having a first rotor for rotating a first working pawl a second workplace having a second rotor for rotating a second working pawl and rotatably connected to a first workplace so that it can switch a stored state and a working state a connection part having a movement regulating groove to regulating the movement of the projection and connected rotatably to the other of the first working part and the second working part and a power unit for transmitting the power to the connection part thereby to rotate the second working part. In the rotation starting state for the second working part to start the rotation, the direction of the tangential line at a contact point between the projection and the inner wall of the movement regulation groove is different from the direction of a straight line joining the projection and the rotation center of the second workplace.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2017,JPO&INPIT【課題】収納状態と作業状態とを切り替え可能な作業機において、連結部の耐久性が高く、安定した延長作業部の回動動作を得ること。【解決手段】作業機は、第1作業爪を回転させる第1ロータを有する第1作業部と、第2作業爪を回転させる第2ロータを有し、収納状態と作業状態とを切り替え可能に、第1作業部に回動可能に接続された第2作業部と、第1作業部及び第2作業部の一方に固定された突出部と、突出部が内側に配置されることで突出部の移動を規制する移動規制溝が設けられ、第1作業部及び第2作業部の他方に回動可能に接続された連結部と、連結部に動力を伝達し、第2作業部を回動させる動力部と、を有し、第2作業部が回動し始める回動開始状態において、突出部と移動規制溝の内壁との接点における接線の方向が、突出部と第2作業部の回動中心とを結ぶ直線の方向とは異なる方向である。【選択図】図7
