<P>PROBLEM TO BE SOLVED: To provide an adjusting door roller for replacement, which is strongly attached to a sash bottom rail and stably and surely operated over a long period of time, even while it is configured to be used by easily being attached to the sash bottom rail of various shapes/sizes. <P>SOLUTION: The adjusting door roller for replacement includes a guide body 4B which extends outwards from front and rear sidewalls in a sash thickness direction H2 of an outer frame 3 and is elastically deformed in the state of being stored inside a storage recessed part formed on the lower surface of a sash bottom rail B, opened downwards and extending in a sash opening/closing direction H1. An attaching flange 5 along an upper wall E is projected at the front and rear in the sash opening/closing direction H1 of the outer frame 3. When an existing door roller which needs to be replaced is detached, an adjusting door roller 1 for replacement is stored inside the storage recessed part D, and the attaching flange 5 is pressed to the upper wall E, it is held in the state of completing positioning in a sash thickness direction H2 by the elastically deformed guide body 4B, and is strongly attached to the sash bottom rail B by screwing a tapping screw G through a through-hole of the attaching flange 5 to the upper wall E of the storage recessed part D. <P>COPYRIGHT: (C)2012,JPO&INPIT |
