ABSTRACT:
This specification discloses a carriage apparatus including a carriage movable relative to a fixed base bed and driven by a feed screw or the like. Means for well guiding the movement of the carriage is provided between the base bed and the carriage. A ball nut threadably fitted on the feed screw for driving the carriage is coupled to the carriage through a housing, and means for absorbing displacement of the ball nut is provided between the two. Further, to prevent chiefly the rotation of the ball nut, a bellows having high rigidity for torsion and low rigidity for the other forces is provided between the ball nut and the carriage.
