Abstract
Disclosed herein is a snap ring which is configured such that pressure which is applied from a purse line to the snap ring or multiple rollers is distributed to two rollers rather than being focused on one roller. A first side part and a second side part of a frame are formed diagonally such that the purse line that is disposed on the first side roller or the second side roller is easily moved towards an intermediate roller along the first side part or the second side part. Thereby, pressure which is applied from the purse line to the snap ring or the multiple rollers can be evenly distributed to the first side roller and the intermediate roller or to the second side roller and the intermediate roller rather than being focused on only one roller. As a result, the lifetime of the snap ring can be increased.
