Abstract:
1. An XY guide table, comprising: a lower plate; an intermediate plate assembled to the lower plate through intermediation of a large number of rolling members and capable of moving in an X-direction; and an upper plate assembled to the intermediate plate through intermediation of a large number of rolling members and capable of moving in a Y-direction which is orthogonal to the X-direction, wherein: each of the lower plate and the upper plate has a pair of rail bodies of a substantially rectangular sectional configuration, in which mounting holes for fastening members are formed, and a connecting plate portion connecting the rail bodies, and is formed in a substantially channel-shaped configuration having between the pair of rail bodies a storage groove whose width corresponds to a width of the connecting plate portion, with a rolling member rolling groove being formed in a side surface of each rail body facing the storage groove; the upper plate and the lower plate are stacked together, with the respective storage grooves of those being opposed and orthogonal to each other; and the intermediate plate is formed in a substantially rectangular configuration, and has a lower half thereof loosely fitted into the storage groove of the lower plate and an upper half thereof loosely fitted into the storage groove of the upper plate, with rolling member rolling grooves being formed at positions thereof opposed to the rolling member rolling grooves formed in the rail bodies of the lower plate and the upper plate.
