Zusammenfassung:To provide an improved shake-off device which can cancel inertial force acting on a reciprocating part without generating vibration in the vertical direction to inertial force of the reciprocating part with a small number of components and with a simple structure, which is small-sized and lightweight.SOLUTION: When a counter weight (44) and a reverse gear (42) perform the rotational movement of revolution around a first rotation axis (C) and rotation around a second rotation axis (E), the gravity center of a reverse part (52) including the counter weight (44) and the reverse gear (42) reciprocates along the same reciprocation axis (A) as a reciprocating part (2).SELECTED DRAWING: Figure 2 【課題】部品点数が少なく、簡単な構造でもって、往復運動部の慣性力に対して垂直方向の振動を発生させずに往復運動部に作用する慣性力を打ち消すことができる、小型かつ軽量の改良された振り落とし装置を提供する。【解決手段】カウンターウェイト(44)と反転ギア(42)が第1の回転軸線(C)の周りの公転と第2の回転軸線(E)の周りの自転の回転運動を行うことにより、カウンターウェイト(44)と反転ギア(42)を含む反転部(52)の重心は、往復運動部(2)と同じ往復動軸線(A)に沿って往復運動する。【選択図】図2
