Abstract: A lens device includes a fixation portion fixed to a lens mechanism and a rotational movement portion that is connected to the fixation portion to be rotationally movable. One of the fixation portion and the rotational movement portion includes a detection member and the other of the fixation portion and the rotational movement portion includes a detection target member and a substrate. The detection target member includes a body portion including an indicator of rotational movement and a plurality of extending portions extending from the body portion. The plurality of extending portions are connected to the substrate.

Abstract: 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.

Abstract: 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.
