    • A lens-barrel device has a movable lens-barrel 10 which holds an imaging lens group 11 and a fixed lens-barrel 20 into which the movable lens-barrel 10 is inserted so as to be movable in an axial direction. The movable lens-barrel 10 has a rear end part 10B including a tapered outer circumferential surface 31, and the fixed lens-barrel 20 has a front end part 20A including a tapered inner circumferential surface 22 that is engaged with the tapered outer circumferential surface 31 of the movable lens-barrel 10. A coiled spring 30 biases the movable lens-barrel 10 forward in the axial direction from the fixed lens-barrel 20. Radial impact forces can sufficiently be absorbed by the coiled spring 30 and by a tapered receiving structure composed of the tapered inner circumferential surface 22 and the tapered outer circumferential surface 31.
    • 透镜镜筒装置具有可移动透镜镜筒10,其保持成像透镜组11和可移动透镜镜筒10插入的固定透镜镜筒20,以便可沿轴向移动。 可动透镜镜筒10具有包括锥形外圆周表面31的后端部分10B,并且固定透镜镜筒20具有前端部分20A,前端部分20A包括锥形内圆周表面22,其与锥形外周面 可移动透镜镜筒10的表面31。 螺旋弹簧30将固定透镜镜筒20沿轴向向前偏压可动透镜镜筒10。 径向冲击力可以被螺旋弹簧30以及由锥形内圆周表面22和锥形外圆周表面31组成的锥形接收结构充分吸收。
