<p>The present invention relates to a snap ring with an easily replaceable support, which allows to concretely support the frictional force of a purse line without having a side roller requiring a complex configuration on the side of a main roller. The snap ring has a support formed in a simple structure instead of a side roller requiring a complex configuration on the inner side of a first side part or a second side part of a frame so that the support and the main roller can concretely support the frictional force of a purse line. Also, the support or the main roller is configured to be replaceable so as to have an effect of easily replacing a worn support or main roller.</p> |
