    • A zoom lens apparatus includes a movable magnification lens component, a stationary barrel, a movable lens holder, and a rotatable cam barrel. Plural cam grooves are formed in the cam barrel, have a pair of cam surfaces opposed to one another, for moving the movable lens holder in the optical axis direction by rotation of the cam barrel relative to the stationary barrel. Plural shaft devices are disposed on a peripheral surface of the movable lens holder, for extending in a radial direction being perpendicular to the optical axis direction. A cam follower device is secured to each of the shaft devices, and inserted in each of the cam grooves. A pair of cam follower surfaces are provided on the cam follower device, deformable resiliently about each of the shaft devices, and pressed by respectively the cam surfaces.
    • 变焦透镜装置包括可移动放大透镜部件,固定镜筒,可移动透镜保持器和可旋转凸轮镜筒。 多个凸轮槽形成在凸轮筒中,具有彼此相对的一对凸轮表面,用于通过凸轮筒相对于固定筒的旋转来移动可移动透镜保持器在光轴方向上。 多个轴装置设置在可移动透镜保持器的外周表面上,用于沿与光轴方向垂直的径向方向延伸。 凸轮从动装置被固定到每个轴装置,并且插入到每个凸轮槽中。 一对凸轮从动件表面设置在凸轮从动件装置上,可围绕每个轴装置弹性变形,并分别被凸轮表面按压。
