摘要： A novel telescopic cover of the present invention has a plurality of protection covers having top plates and vertically-suspended plates vertically suspended from the top plates, and being arranged so as to cover a guiding portion of a machining tool or the like in a freely stretchable manner between every adjacent pair of the protection covers, while being linked with each other by a linking mechanism which is configured by a plurality of linking elements linked so as to be rotatable around connecting shafts, wherein the telescopic cover has a plurality of guide rails provided to the plurality of protection covers, each having a guide groove which has one and the other guiding surfaces opposed with each other, in the direction normal to the direction of stretching and shrinkage of the entire portion of the protection covers; and a plurality of rolling elements arranged in guide groove, so as to be freely rotatable around each connecting shaft which extends in the depth-wise direction of the guide groove.
