摘要：
A driving apparatus includes: a first member including a first linear groove; a second member including a second linear groove; a plurality of first rolling bodies held between the first and the second linear grooves; a pressing member for pressing the first and second members; a pressing force applying member for pressing the pressing member; and second rolling bodies arranged on the same plane between the second member and the pressing member. A third linear groove for guiding the second rolling bodies is formed on one of the second member and the pressing member. At least one or more of the second rolling bodies are arranged on both sides of the central axis of the first rolling bodies, and the pressing force applying member applies a pressing force to the second rolling bodies such that rotational moment around the axis line is zero.
