Summary:The cord guard 1 having a cylindrical hollow passage 5 into which a cord 3 can be inserted and a flange portion 11 at one end which is retained by a cord guard retainer 9 in a half housing 7. The cord guard 1 further having a tapering wall portion 13 the wall thickness of which is gradually reduced from the flange portion 11 toward the free end, a constant wall portion 15 extending in series from the tapering wall portion 13 further toward the free end with its wall thickness constant, and a thicker wall ring flange 17 provided along the periphery of the free end of the constant wall portion 15. The wall thickness and the length of the constant wall portion 15 are determined such that the constant wall portion 15 is provided with a bending strength low enough that it is flexed smoothly together with the cord 3 when a load approximately equal to the weight of the cord 3 is applied as a bending load.
