PURPOSE: To simplify installation work by providing a holding groove forming its wholeshape integrally molded out of elastic synthetic resin and curved along the shape of a hook part of a hanger bar and opened to the side so as to elastically hold the hook part by way of pushing it from the side into it.
CONSTITUTION: A protective cover 15 is integrally assembled on a hanger ear 11 by way of pushing a hook part 14 into a holding groove 16 from the side. At this time an elastic clamping piece 17 is elastically pushed open, restored after fitting of the hook part 14 is completed and certainly holds the hook part 15 in the holding groove 16. Consequently, as the hanger ear 11 and the protective cover 15 are integrated and never separated, it is easy to handle them at the time of storage, transportation, etc. At the time of installation work, the hanger ear 11 is arranged so that a suspension line M comes below the hook part 14, and when it is pulled down below while turning it axially by 90°, the suspension line M enters the inside of a loop along a curve from an opened part.
