Abstract
A cord tightening device comprises a case having a pair of front and rear plates and a pair of opposite lateral walls interconnecting the front and rear plates and having forwardly converging inner surfaces defining a small-width opening at one end thereof and a large-width opening at the other end thereof, and a sliding member slidably disposed inside the case and having pressing parts formed on opposite lateral surfaces thereof and adapted to press a cord against the opposite lateral walls of the case. The cord tightening device is provided on at least one sliding surface of either one of said case and said sliding member taken as a set with a sliding groove and on at least one sliding surface of the remaining member of the set with a sliding protrusion fit for insertion into said sliding groove. The sliding groove has a regulating part for preventing the sliding protrusion from throwing off the sliding groove, and a lateral surface of either one of the sliding protrusion and the regulating part facing to the other member is slanted to form a slanted part for guiding insertion of the sliding protrusion into the sliding groove.
