<p>PROBLEM TO BE SOLVED: To provide a rail of a slide type fitting capable of safely closing a movable part and capable of also opening by light force, with a simple constitution.SOLUTION: A sash 30 stored in a frame 20 is opened and closed in the horizontal direction when a door roller 50 travels on a lower rail 44. The lower rail 44 comprises a first section S1, a second section S2 having a downward pitch and a third section S3 in order toward an opening position from a closing position of the sash 30 with a height difference. When opening the sash 30, since the door roller 50 descends in the second section S2 by dead weight of the sash 30, the sash 30 can be opened by light force. When closing the sash 30, the second section S2 becomes resistance, and can prevent sudden closing.</p> |
