To provide a ratchet device capable of reducing the number of components.SOLUTION: A ratchet device 2 comprises: an operation input member 110 that can pivot from a neutral position toward a first turning direction A1 in respect to a housing 50; a rotary member 130 that can be rotated in respect to the housing 50; a transmission member 120 that can be moved in a rotation axis line direction of the rotary member 130 in respect to the housing 50 and can transmit a rotation torque got from the operation input member 110 to the rotary member 130; and a return spring 70 that returns the operation input member 110 to its neutral position. The operation input member 110 has a protrusion 112. The transmission member 120 has a first gear 126 and a long hole 122 engaged with the protrusion 112 when the operation input member 110 is turned from the neutral position toward the first turning direction A1 to move the transmission member 120 from its initial position to one side of the rotation axis line direction. The rotary member 130 has a second gear 136 to which the first gear 126 is engaged when the transmission member 120 is moved from its initial position to one side of the rotation axis line direction.SELECTED DRAWING: Figure 7

    【課題】部品点数を少なくすることができるラチェット装置を提供する。【解決手段】ラチェット装置2は、筐体50に対し中立位置から第1回動方向A1に回動可能な操作入力部材110と、筐体50に対し回転可能な回転部材130と、筐体50に対し回転部材130の回転軸線方向に移動可能であり、操作入力部材110からの回転トルクを回転部材130に伝達可能な伝達部材120と、操作入力部材110を中立位置に戻すリターンスプリング70とを備える。操作入力部材110は、凸部112を有する。伝達部材120は、第1ギヤ126と、操作入力部材110が中立位置から第1回動方向A1に回動した場合に凸部112と係合して伝達部材120を初期位置から回転軸線方向の一方側に移動させる長穴122とを有する。回転部材130は、伝達部材120が初期位置から回転軸線方向の一方側に移動した場合に第1ギヤ126が係合する第2ギヤ136を有する。【選択図】図7
