SWIVEL BOOT
PROBLEM TO BE SOLVED: To provide a boot hardly broken, which can also improve workability.SOLUTION: A cylindrical part 3 of a swivel boot 1 is fixed to an outer peripheral surface of a stem 32 of a swivel joint 31 as a result of being tightened by a band member 43 from an outer surface side with its inner surface contacting with the outer peripheral surface of the stem 32. At that time, a plurality of projections 5 of the swivel boot 1 located on sides of the cylindrical part 3 are contacted by the band member 43 from an axial direction C.
【課題】作業性を向上させるとともに、破れにくくすることができるようにする。【解決手段】スイベルブーツ1の円筒部3は、内面がスイベルジョイント31のステム32の外周面に当接された状態で、外面側からバンド部材43で締め付けられることで、ステム32の外周面に固定される。このとき、円筒部3の側方に位置するスイベルブーツ1の複数の突起部5には、軸方向Cからバンド部材43が当接される。【選択図】図3
