とする請求項１記載のスライドテーブル装置。[Claims for Utility Model Registration] 1. A table support mechanism that guides and slidably supports the table by disposing a group of circulating balls between the guide and the table, and a table feeding mechanism that linearly moves the table along the guide. The table support mechanism is provided with one stage and two rows of circulation orbits between the guide and the table, and each of these circulation orbits is provided with a circulation ball group, and the circulation ball group and 2 in the preload direction
A slide table device characterized in that a preload contact surface that makes preload contact at a point is formed in a circulating orbit, and the preload contact surface is formed in each preload section according to the preload direction. 2. The preload section consists of a preload section A and a preload section B that are alternately connected along a circulation track. It has a preload contact surface that makes preload contact with the circulating ball group at two points, and in preload section B, it has a preload contact surface that makes preload contact with the lubricating ball group at two points in the preload direction that slopes outward as it goes toward the table surface side. The slide table device according to claim 1, wherein the slide table device has a surface.
