A motor-installed roller (3) has a roller body (6) with ends closed with fixtures (7), and apertures (30,31) are formed in the roller body and fixtures, respectively. A recess (32) also formed in each fixture (7) extends in axial direction of this fixture so as to communicate with the aperture (31). A hollow pin (9) as the fastener has a solid basal portion (36) and a collapsible foot (35). This foot is deformed by an external force applied to the solid portion in its axial direction, so as to extend along the inner surface of the recess (32) such that the hollow pin (9) is locked in place not to slip off even if subjected to vibration. The solid portion (36) of this pin prevents the roller body (6) from moving relative to the fixture (7), or relative to any closures, bearings or the like easily attached to the roller.
A roller device comprising:
A roller device comprising:
A method of making a roller device that comprises a roller body, a fixture accommodated at least in part in the roller body and secured thereto, and a fastener fixedly connecting a periphery of the fixture to a periphery of the roller body, with the fastener comprising at least one transverse key that is composed of a columnar solid portion and a cylindrical collapsible foot continuing therefrom, and the key is designed such that a thrust applied axially of the key to the solid portion expands the collapsible foot radially and outwards so as to inhibit the key from moving axially thereof, and the solid portion is retained in place to prevent the fixture from moving relative to the roller body, the method comprising the steps of:
