PROBLEM TO BE SOLVED: To easily regulate energizing force according to dispersion, etc. of sliding resistance of a telescopic cover. SOLUTION: This telescopic cover is made of a cover component 21 to be extended and elongated in a Z direction according to moving of a mobile body 52. The cover component 21 is provided with a plurality of movable cover members 41 and 42 which are capable of separately moving by overlapping in a direction orthogonal to the Z direction. The two adjacent movable cover members 41 and 42 are elastically energized in the Z direction by an air cylinder 71. COPYRIGHT: (C)2007,JPO&INPIT
