Device for tying shoelaces

Abstract

Disclosed therein is a lace fastening device is easy to use and simple in structure since a fastening member is fastened to the inside of a receiving member the moment a control member is rotated and restored to its original location and the fastened state of the fastening member is released when a user rotates the control member to separate the fastening member from a magnetic body. An end portion of a lace is inserted into a fixing member and stackingly fastened inside the fixing member. The lace fastening device can stably fasten the lace to a footwear since a tightly fastened state of the lace can be kept while the upper end portion of the laminated lace pressurizes the lower end portion of the lace, thereby improving productivity.
