Telescopic cover

A telescopic cover for covering a guide portion for guiding a movable part of an industrial machine, comprising:

• a first fixed cover panel fixed to the movable part and configured to move together with the movable part;
• a second fixed cover panel fixed to the fixed part of the industrial machine;
• a movable cover panel disposed between the first fixed cover panel and the second fixed cover panel and configured to overlap with the first fixed cover panel and the second fixed cover panel;
• a guide rail laid on the movable cover panel and oriented in the direction perpendicular to the moving direction of the movable part;
• and
• first and second V-shaped link structures, which each include two link arms, a movable pin configured to be movable along the guide rail and rotatably support the two link arms at one end of the two link arms, a first fixed pin fixed to the first fixed cover panel and configured to rotatably support the other end of the link arm and a second fixed pin fixed to the second fixed cover panel and configured to rotatably support the other end of the link arm,
• wherein the first V-shaped link structure and the second V-shaped link structure are arranged in an overlapping manner such that the first fixed pin and the second fixed pin of the first V-shaped link structure are positioned relative to the movable pin to one side with respect to the direction parallel to the longitudinal direction of the guide rail while the first fixed pin and the second fixed pin of the second V-shaped link structure are positioned relative to the movable pin to the side opposite to the one side in the first V-shaped link structure.
