Filaire element e.g. cable`s optic fiber, rotating case, has articulation unit formed on peripheral walls, and including cylindrical finger housed in recess by slight plastic deformation to form articulation between case and adjacent case

摘要

The case (2) has a wall forming a flat bottom (4) of the case, and an articulation unit (6) formed on peripheral walls (5, 7) with respect to an adjacent case (2`). The articulation unit includes a cylindrical finger and a recess, which are integrated to one of the peripheral walls of the case (2). The cylindrical finger is housed in the recess by a slight plastic deformation for forming an articulation between the case and the adjacent case.
