To provide an operation part unit capable of forming a separate operating unit by incorporating the operation part unit as it is into the control unit housing of a power loading part separately manufactured instead of the operating unit separately manufactured for a heavy duty-type load handling device, as well as the operating unit for a standard type can be formed by incorporating the operation part unit into the box-shape body of the load handling device for a standard-type.SOLUTION: A unitized operation part unit comprises: a lever shaft 1 having an operation lever 2 on one end of the lever shaft and orthogonal to the operation lever 2; a plate 5 with flange which has a bearing 4 of the lever shaft 1 and through which the other end of the lever shaft 1 passes from its front face to be arranged; a rotation regulating part CL of the lever shaft 1 fixed to the lever shaft 1 behind the plate 5 with flange, and having a self-recovery function for the forward and reverse rotations of the lever shaft 1; a cover 6 with flange which is placed over the back of the plate 5 with flange so as to sandwich the rotation regulating part CL and through which the tip side of the lever shaft 1 passes via the bearing 7; and a potentiometer 15 which is installed on the back face of the cover 6 with flange and to which the rotation of the lever shaft 1 is transmitted.SELECTED DRAWING: Figure 1
【課題】 標準タイプの荷重取扱装置のボックス状本体に組み込んで標準タイプ用の操作部に形成できると共に、大荷重タイプの荷重取扱装置のために別製されていた操作部に代えて別製したパワー負荷部の制御部の筐体にそのまま組み込んで別体操作部に形成できる操作部ユニットを提供する。【解決手段】 操作レバー2を一端に備えて前記操作レバー2に直交したレバー軸1と、前記レバー軸1の軸受4を備えそのレバー軸1の他端側が前面から貫通して配置されるフランジ付プレート5と、前記フランジ付プレート5の後ろで前記レバー軸1に固定され前記レバー軸1の正,逆回転の自己復帰機能を有する前記レバー軸1の回転規制部CLと、前記回転規制部CLを挟む形で前記フランジ付きプレート5の背面に被せて配置され前記レバー軸1の先端側が軸受7を介して貫通するフランジ付カバー6と、前記フランジ付カバー6の背面に設けられて前記レバー軸1の回転が伝動されるポテンシヨメータ15を備えてユニット化して操作部ユニットにした。【選択図】 図1
