ABSTRACT:
A cord bushing including a bushing body, the bushing body having a head portion permitting insertion therethrough of a cord, a trunk portion contiguous to the head portion and having an uneven inner surface, and a cord protecting portion contiguous to the trunk portion for protecting the cord inserted therethrough, the head portion having a fitting notched portion formed therein, and the cord protecting portion comprising plural rings each having a cord insertion hole and interconnected by flexible connections; a cord holding member capable of being engaged with and disengaged from the fitting notched part of the head portion and having an uneven inner surface which can hold the inserted cord in corporation with an uneven inner surface of the head portion; and expansible elastic retaining portions formed integrally with the head portion by notching part of the head portion in the vicinity of the said fitting notched part, the portion except the base end of each of the elastic retaining portions being cut away for displacement by a notch extending through the wall of the head portion. Such a construction permits easy and positive mounting of the cord bushing to a panel, a chassis or the like regardless of variation of the cord diameter. Besides, since the diameter of the panel mounting portion of the bushing body is constant independently of the cord diameter, the tolerance in manufacture for the diameter of a fixing hole formed in a panel or the like can be taken large, which leads to reduction of the cost.
