PURPOSE:To prevent the meandering and torsion of a telescopic cover and to prevent the generation of a foreign sound and damage by making the telescopic amt. among each nodal point of a support coincident with the telescopic motion amt. of between the partial covers to which the nodal point is fitted. CONSTITUTION:A support 13 is arranged at the inside along the telescopic direction of a telescopic cover, and each nodal point 21 is fitted to each support fitting only capable of turning a link 22 on the respectively corresponding partial bars 12a-12g. The length of this link 22 varies on each nodal point 21, the telescopic motion of each partial cover 12a-12g is made proportional to an analog dimension and the moving amt. is made small in order from the other end side to one end side. So that, the length of the link 22 at each nodal point 21 is shortened in order as well by aligning thereto and the telescopic amt. among each nodal point 21 is formed almost equal to the telescopic amt. of between the partial covers fitted with the nodal point 21. |
