| 发明名称 | Lens barrel and imaging device | ||
| 摘要 | An object is to realize further size reduction in a lens barrel in which a barrel unit is rotatable in three axis directions. The lens barrel includes a support portion for supporting the barrel unit, a part of the support portion being fixed to an external member, an actuator including a drive base movable in a direction parallel to a surface passing through an optical axis of the barrel unit, and a universal joint mechanism portion for linking the barrel unit and the drive base of the actuator. The support portion supports the barrel unit rotatably about a pitch axis, a roll axis, and a yaw axis with respect to the optical axis direction, and the actuator drives the barrel unit about the pitch axis, the roll axis, and the yaw axis by moving the drive base. | ||

| 主权项 | 1. A lens barrel comprising: a support portion for supporting a barrel unit, a part of the support portion being fixed to an external member; an actuator including a drive base movable in a direction parallel to a plane including an optical axis of the barrel unit; and a universal joint mechanism portion for linking the barrel unit and the drive base of the actuator, wherein the support portion supports the barrel unit rotatably about a pitch axis, a roll axis, and a yaw axis with respect to an optical axis direction, and wherein the actuator drives the barrel unit about the pitch axis, the roll axis, and the yaw axis by moving the drive base. | ||
