Abstract

In an infrared spectrophotometer, a plurality of rolling elements are provided between a movable portion and the holding portion. While no external force is applied from a spring, a play space is generated between the movable portion, the holding portion, and each rolling element. In the infrared spectrophotometer, when the movable mirror and the movable portion are slid, an external force directed downward is applied to the movable portion by the spring, thereby preventing each rolling element from moving between the movable portion and the holding portion. Accordingly, when the movable mirror and the movable portion are slid, it is possible to suppress rattling of the movable portion and the holding portion while leaving a fine gap between the movable portion, the holding portion, and each rolling element. This makes it possible to easily control the moving speeds of the movable mirror and the movable portion and to suppress rattling of the movable mirror and the movable portion.
