摘要： The disclosure shows a sealing member secured to the inner end of a compressor stator vane row by bolts and nuts. One form of bolt retainer prevents a loosened bolt from entering the flow field. The retainer is of hollow, box-like cross section with keyhole slots in its inner wall for assembly and access holes in its outer wall for insertion of an allen wrench to torque the bolts. Another form of bolt retainer provides access to the outer portion of the bolt heads so that they may be tightened and loosened. A third form of retainer may be assembled laterally and comprises a plate and retainer lugs for the bolts.
