摘要： A lens unit includes a guided portion that includes a first bearing portion and a second bearing portion disposed to be spaced apart from each other in a direction X and is slidably supported by a guide shaft, and a lens holding member. The lens unit includes a first tilt-preventing member having a linear expansion coefficient lower than a linear expansion coefficient of the lens holding member. The first tilt-preventing member is fixed to a region of the guided portion positioned between the first bearing portion and second bearing portion.

摘要： Provided are an image blur correcting device that capable of improving a degree of freedom in design and realizing miniaturization or weight reduction, a lens device including the image blur correcting device, and an imaging device including the lens device. An image blur correcting device includes a fixing member, a first movable member that is supported by the fixing member in a state of being movable in a direction X, and a second movable member that is supported by the first movable member in a state of being movable in a direction Y A second coil that drives the second movable member is fixed to one first surface of the second movable member in a direction Z, and a first coil that drives the first movable member is fixed to the other second surface of the second movable member in the direction Z.

摘要： A lens unit includes a guided portion that includes a first bearing portion and a second bearing portion disposed to be spaced apart from each other in a direction X and is slidably supported by a guide shaft, and a lens holding member. A first distance between the center of a fixing portion of the lens holding member and the center of the first bearing portion in the direction X is set to be longer than a second distance between the center of the fixing portion and the center of the second bearing portion in the direction X. A first tilt-preventing member having a linear expansion coefficient lower than that of the lens holding member is fixed to a region, which is closer to the first bearing portion than the center of the fixing portion, of a portion of the guided portion positioned between the first and second bearing portions.
