Disclosed is a tension delivery device for preventing urinary incontinence, which includes: Retzius space-insertion portions which are respectively to be inserted into the Retzius spaces positioned on the left side and right side of the urethra and move in response to the pressure or the Retzius spaces; and a urethral support portion which extends convergently from the Retzius space-insertion portions and serves to support the urethra upward, wherein the lateral cross section of the urethral support portion becomes thinner from Retzius space-insertion portions toward the distal end, and a mesh structure may be provided along the outer surface of the tension transfer device. The device can sufficiently inhibit urinary incontinence, and is minimally invasive so that damage associated with an invasive method can be reduced.
