LENS DEVICE, IMAGING DEVICE, AND MOVING BODY

SOLUTION: A lens device may comprise: a first holding member which holds a lens; a second holding member which holds the first holding member; a first transmission member which transmits power for moving the first holding member in a first direction to the first holding member; driving mechanisms which make the first transmission member move in the first direction and a second direction; a second transmission member which is movably held by the first holding member along the first direction and the second direction relative to the first holding member, which is pushed by the first transmission member in response to movement of the first transmission member in the first direction and moves in the first direction, thereby transmitting the power to the first holding member to move the first holding member in the first direction; a first elastic member which pushes the first holding member toward the second holding member by force having a component in the second direction, and which moves the first holding member along with the first transmission member in the second direction in response to movement of the first transmission member in the second direction; and a second elastic member which pushes the second transmission member towards the first holding member by force having a component in the second direction, and which presses the second transmission member towards the first transmission member.SELECTED DRAWING: Figure 9 【解決手段】レンズ装置は、レンズを保持する第１保持部材と、第１保持部材を保持する第２保持部材と、第１方向に移動させるための動力を第１保持部材に伝達する第１伝達部材と、第１伝達部材を第１方向及び第２方向に移動させる駆動機構と、第１保持部材に対して第１方向及び第２方向に沿って移動可能に第１保持部材に保持され、第１伝達部材が第１方向に移動することに応じて第１伝達部材に押されて第１方向に移動することで、第１保持部材に動力を伝達して第１保持部材を第１方向に移動させる第２伝達部材と、第１保持部材を第２保持部材に対して第２方向の成分を有する力で押し、第１伝達部材が第２方向に移動することに応じて第２伝達部材とともに第１保持部材を第２方向に移動させる第１弾性部材と、第２伝達部材を第１保持部材に対して第２方向の成分を有する力で押し、第２伝達部材を第１伝達部材に押し付ける第２弾性部材とを備えてよい。【選択図】図９
