する負荷軽減機構。(1) An electromagnetic actuator that can reciprocate, an actuating member that reciprocates in conjunction with the operation of the electromagnetic actuator, and a clamping member that includes a pair of levers that hold the actuating member in a neutral position by the action of springs. In the electromagnetic drive device for a camera, the pair includes a weighted lever that presses one of the levers by tilting according to changes in the posture of the camera during shooting to apply a force that resists the force of the spring. 1. A load reduction mechanism, characterized in that the load reduction mechanism is arranged between the levers of the electromagnetic actuator to reduce the load applied to the electromagnetic actuator when the actuating member is operated in a direction opposite to gravity.

によって絞り口径が小さくなり、他方向へ動作すること
によって絞り口径が大きく設定されることを特徴とする
前記実用新案登録請求の範囲第１項記載のカメラ用電磁
駆動装置の負荷軽減機構。(2) The actuating member is an aperture lever member that sets the aperture aperture in its neutral position, but by operating in one direction the aperture aperture becomes smaller and by operating in the other direction the aperture aperture is set larger. A load reduction mechanism for an electromagnetic drive device for a camera according to claim 1, characterized in that:
レバ一部材であり、中立位置においである距離にピント
が合っているが、一方向へ動作することによって遠い距
離にピントが合わせられ、他方向へ動作することによっ
