    Abstract: To provide an actuator in which an unstable movement of a rotor is controlled. An actuator includes a coil, a bobbin around which the coil is wound, a rotor positioned inside the bobbin, a shaft to which the rotor is fixed and which is rotatably supported, a stator including a base portion positioned on one end side of the shaft, outer magnetic pole portions extending from the base portion along the shaft and positioned outside the bobbin and inner magnetic pole portions extending from the base portion along the shaft and positioned between the rotor and the inside of the bobbin, a stator including a base portion positioned on the other end side of the shaft, outer magnetic pole portions extending from the base portion along the shaft and positioned outside the bobbin and inner magnetic pole portions extending from the base portion along the shaft and positioned between the rotor and the inside of the bobbin and a cover positioned between the rotor and the stator and contacting tip portions of the inner magnetic pole portions to regulate the approach of the inner magnetic pole portions to the rotor.

    Abstract: To provide a blade drive device that may prevent malfunction of blades. A blade drive device includes a base plate having an opening to be opened and closed by a blade on an optical axis, and a flexible substrate having joint portions to which conductor wires of a first actuator and a second actuator that drive the blades are joined, the flexible substrate being provided between the base plate and the blades on one side of the base plate in an axis direction of the optical axis. The base plate is provided with a substrate housing part in which at least a part of the flexible substrate is housed and to which a covering material for covering the joint portions is applied. The substrate housing part is provided with wall surface extending from the other side toward the one side in the axis direction of the optical axis. The wall surface is provided with corner portions extending along a direction crossing the axis direction of the optical axis. The corner portions are provided between the blades and the flexible substrate in the axis direction of the optical axis.
