<p><P>PROBLEM TO BE SOLVED: To provide easy-to-be-handled packing 1 such as maintenance, excellent in sealing performance, and without braking bellows 21 by a reaction force, in packing 1 for bellows installed on an outer peripheral side of the bellows 21 to seal between an outer peripheral face of the bellows 21 and an inner peripheral face of the housing 31 in which the bellows 21 are inserted. <P>SOLUTION: An annular inner peripheral part 2 inserted and installed in a valley-fold part 23 of the bellows 21, an annular outer peripheral part 3 disposed on an outer peripheral side of the valley fold part 23 and mountain-fold parts 22 on both sides of the valley-fold part 23, and a joining part 4 connecting the inner peripheral part 2 with the outer peripheral part 3 and having small width in an axial direction, are integrally provided. The inner peripheral part 2 has a projecting inner peripheral seal part 5 disposed to an axial end face thereof to be in close-contact with a side face 23b of the valley-fold part 23. The outer peripheral part 3 has an outer peripheral seal part 6 disposed to an outer peripheral face thereof to be in close-contact with the inner peripheral face of the housing 31. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
