PURPOSE: A guide rail for a sliding door is provided to prevent the separation of a roller from the guide rail by preventing the piling of dust and foreign material on the contact surface between roller and a rail. CONSTITUTION: A guide rail for a sliding door comprises a polyhedral main body(102), an open groove(104), and a impurity storage groove(106). The polyhedral main body is installed on the top of the door frame along the longitudinal direction of the door frame. The open groove is formed on the top of the polyhedral main body at a tilt. A roller is settled on the open groove to move. The roller is installed in the lower-part of a sliding door(200). The impurity storage groove is formed inside the main body to store the foreign materials flowing through the open groove. |
