The present invention relates to a rope guide roller. The rope guide roller has a roller body which has a body part and a journal part. The body part is supported to a fixed shaft to be rotated and has a hollow part into which the fixed shaft is inserted and a contact surface touching a rope. The journal part is formed on the inner side of the body part and point-contacts with the outer surface of the fixed shaft to support the body part to the fixed shaft to be rotated and prevents friction between the inner surface of the hollow part and the outer surface of the fixed shaft. Multiple balls are molded in the journal part. The rope guide roller according to the present invention enables a long time use by removing a bearing made of a metal material and reducing corrosion and malfunction rates caused by the inflow of seawater. |
