PROBLEM TO BE SOLVED: To provide an imaging device that comprises a configuration achieving improvement in miniaturization and assemblability without falling mobility of a movement frame in a holding frame.SOLUTION: An imaging device comprises: a movement lens 41 that forms an optical image of an object a movement frame 40 that holds the movement lens 41 a holding frame 30 that holds the movement frame 40 movably along an optical axis direction L at least one groove 200 that is formed along the optical axis direction L in an outer peripheral surface 40g2 of the movement frame 40, and accumulates a lubricant O coated between the outer peripheral surface 40g2 and an inner peripheral surface 30n1 and a magnetism member 50 that urges the movement frame 40 in one direction K1 along a radial direction K of the holding frame 30, and thereby causes the outer peripheral surface 40g2 to abut on the inner peripheral surface 30n1 in a prescribed area T, in which the groove 200 is formed at a position N adjacent to the prescribed area T.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2018,JPO&INPIT【課題】保持枠内における移動枠の移動性を低下させることなく小型化及び組立性の向上を図った構成を具備する撮像装置を提供する。【解決手段】物体の光学像を形成する移動レンズ41と、移動レンズ41を保持する移動枠40と、移動枠40を光軸方向Lに沿って移動自在に保持する保持枠30と、移動枠40の外周面40g2に光軸方向Lに沿って形成された、外周面40g2と内周面30n1との間に塗布された潤滑剤Oを溜める少なくとも1本の溝200と、移動枠40を保持枠30の径方向Kに沿った一方向K1に付勢することにより、外周面40g2と内周面30n1とを所定領域Tにて当接させる磁性部材50と、を具備し、溝200は、所定領域Tに隣接する位置Nに形成されている。【選択図】図6
