Zusammenfassung:To provide a positioning unit which enables high accuracy positioning in a one-dimensional direction or a two-dimensional direction (a plane direction), and to provide a positioning table.SOLUTION: A positioning unit includes: a first track fixed onto a substrate; a first slide member which is slidably attached to the first track and includes an inclined surface perpendicular to the substrate on a side surface; a linear motion driving device which is connected to the first slide member, installed on the substrate, and drives forward/rearward movement of the first slide member along the track; a second track fixed onto the substrate so as to intersect with the first track; and a second slide member slidably attached to the second track and including an inclined surface perpendicular to the substrate on a side surface. The first slide member and the second slide member are assembled so that the second slide member is moved rearward or forward along the track when the first slide member is moved forward or rearward along the track by the linear motion driving device being operated with the inclined surfaces contacting with each other. A positioning table uses the positioning unit.SELECTED DRAWING: Figure 1 【課題】一次元方向または二次元方向(平面方向)での高精度の位置決めを可能にする位置決めユニット及び位置決めテーブルを提供する。【解決手段】基板の上に固定された第一の軌道;この第一の軌道に摺動可能に装着されている、基板に対して垂直な傾斜面を側面に備えた第一の摺動部材;この第一の摺動部材に連結している、前記基板に設置された、第一の摺動部材の軌道に沿う前進後退運動を駆動する直線運動駆動装置;前記基板の上で、第一の軌道に交差するように固定された第二の軌道;そしてこの第二の軌道に摺動可能に装着されている、前記基板に対して垂直な傾斜面を側面に備えた第二の摺動部材を含み、第一の摺動部材と第二の摺動部材とが、それらの傾斜面が互いに接触した状態での直線運動駆動装置の作動により発生する第一の摺動部材の軌道に沿う前進後退運動によって第二の摺動部材が軌道に沿う後退前進運動を行うように組み合わされた位置決めユニット、そしてこの位置決めユニットを用いた位置決めテーブル。【選択図】図1
