PURPOSE:To prevent shifted loading by making an arched window in the hab at the output side while corresponding window in the cover at the input side then placing a plurality of torsion springs and idling spacers in circumferential direction between both windows. CONSTITUTION:An arched window 15 is made in a hab 1 except the arm 7 while windows 10 corresponding with the window of arm are made in main and sub- covers 3, 4 at the input side. Idling spacers 12, 13 are arranged between coil springs 21-23 provided in each window and supported slidably in the circumferential direction by means of rail sections 15a, 15b at the inner/outer circumferences of hab window 15, thereby the rail section 15a of hab 1 can support the centrifugal force to be applied onto the idling spacers 12, 13 to eliminate necessity of providing highly accurate guide faces on the covers 3, 4 while to protect the coil springs 21-23 from shifted loading. |
