ABSTRACT:
A roller assembly fitting device for selectively locking the retraction of the pivot, which is inserted in a bore in a mounting bracket to support the roller assembly in both brackets. The device has a roller-end sleeve fixed to the roller assembly, a guide sleeve rotatably mounted in the roller-end sleeve, a pivot retractably mounted in the guide sleeve, and a coil spring interposed between the guide sleeve and the pivot to bias them in opposite directions. The guide sleeve has its radial projection for selectively fitting engagement with axial and peripheral grooves formed in the outer periphery of the pivot. The pivot is retractable when the guide sleeve is in the first position in which the projection is in the axial groove but locked when the guide sleeve is in the second position in which the projection is in the peripheral groove.
