Abstract
In a cover apparatus of a machine tool, a slide cover and turning covers are connected to a motor via an up-down movement mechanism and a cam drive portion. During operation of the motor, the slide cover and the turning covers are raised from a lowermost position to an uppermost position, and are held at the uppermost position, and then are lowered from the uppermost position to the lowermost position. The turning covers are connected to the motor also via a pivoting mechanism and an intermittent drive unit. During operation of the motor, the turning covers are turned while being held at the uppermost position. The apparatus thus prevents deviations of the up-down movement timing of the slide cover 47 and the up-down movement timing of the turning covers, thereby improving reliability.
