Disclosed is an apparatus for equalizing tensions among elevator wire ropes, which immediately eliminates imbalance and equalizes the tensions among elevator wire ropes in the event of differences in the lengths of elevator wire ropes, thereby improving safety, durability and reliability. The apparatus automatically corrects imbalance caused by changes in the lengths of a plurality of elevator wire ropes (700) to maintain a balance in the tensions of elevator wire ropes. The apparatus includes a body (200f) formed therein with a receiving space; a tension adjustment unit coupled to a plurality of belts (10f, 20f, 30f and 40f) connected to the elevator wire ropes (700), respectively, and installed in the body (200f); a main rotary shaft (50f) rotatably coupled to the body (200f) by passing through the tension adjustment unit; and first and second external gears (45f and 48f), which are fixed to the main rotary shaft (50f) such that the first and second external gears (45f and 48f) are rotatable, and which are coupled to the front and rear surfaces of the tension adjustment unit to transmit rotating forces.
