    • The objective of the current invention is to provide a boot-band that can be surely fastened around a member to be clamped without any portion of the band body buckling during fastening, and that can be fastened by a one-step operation for improved fastening workability. A boot-band 30 comprising (1) a band body 31 that is wound like a ring around a member to be clamped, and that has, at its respective ends, an outer-layer portion 32 that is overlaid over an inner-layer portion 33, (2) engagement holes 34, 35 that are formed in the outer-layer portion 32, (3) engagement pawls 36, 37 that are formed on, and that protrude radially outwardly from, the inner-layer portion 33, and that are to be engaged with the corresponding engagement holes 34, 35 so that the band body is held in a fastened state, (4) a first boot-band pawl 41 that is formed on the inner-layer portion 33 at a location nearer to the longitudinal end of the band body than the engagement holes 34, 35 are, (5) a second boot-band pawl 38 that is formed on the inner-layer portion 33 and that is to be engaged with the first boot-band pawl 41, and (6) a pressure-reduction means 45 that is formed in the outer-layer portion 32 in such a manner that the pressure-reduction means 45 reduces the pressure applied on the engagement pawls 36, 37 of the inner-layer portion 33 when the outer-layer portion 32 climbs over the engagement pawls 36, 37 just before the first and the second boot-band pawls are engaged.
    • 本发明的目的是提供一种可以牢固地固定在待夹紧的构件周围的靴带,而在紧固期间带体的任何部分都不会弯曲,并且可以通过一步操作来固定以提高紧固可操作性 。 靴带30,其包括:(1)带状体31,其被围绕待夹持的构件缠绕成环状,并且在其端部具有覆盖在内层部分上的外层部分32 33,(2)形成在外层部分32中的接合孔34,35,(3)形成在内层部分33上并且从内层部分33径向向外突出的接合爪36,37,并且 与相应的接合孔34,35接合,使得带体保持在紧固状态;(4)第一自由带棘爪41,其形成在内层部分33的更接近 带状体的纵向端部比接合孔34,35的长度方向的端部为(5)形成在内层部33上且与第一靴带卡爪41卡合的第二靴带棘爪38, 和(6)减压装置45,其形成在外层部分32中,使得减压装置45减小压力 当外层部分32刚好在第一和第二靴带棘爪接合之前爬过接合爪36,37时,再施加到内层部分33的接合爪36,37上。
