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.
