Une unité de support (13) et des unités d'entraînement (14A, 14B, 14C, 14D) sont disposées entre la base (1) et la table supérieure (4a) et au niveau de parties qui sont disposées en zigzag par rapport à la direction de déplacement de charge (L) pour correspondre au centre et aux quatre coins de la table supérieure (4a), l'unité de support (13) étant pourvue de trois degrés de liberté de X, Y, et θ, et l'unité d'entraînement comprenant un mécanisme à mouvement linéaire de vis à bille dans la direction uniaxiale (9) en plus de la structure similaire à l'unité de support (13). Les mécanismes à mouvement linéaire de vis à bille (9) d'une paire d'unités d'entraînement disposées en diagonale (14A, 14B) sont disposés pour être orthogonaux aux mécanismes à mouvement linéaire de vis à bille (9) de l'autre paire d'unités d'entraînement disposées en diagonale (14C, 14D). La charge de déplacement appliquée à la table supérieure (4a) par le biais de la pièce tout en se déplaçant dans la direction de déplacement de charge (L) est successivement reçue par les unités d'entraînement respectives (14A, 14C), l'unité de support (13), et les unités d'entraînement respectives (14B, 14D), de manière à empêcher la déformation de la table supérieure (4a).
