Abstract
A method for producing a motorized roller formed by accommodating a motor in a roller body so that the roller body is rotated when being driven by the motor, including the steps of: providing at least one elastic body; providing a bag for accommodating the elastic body; inserting the elastic body into the bag; removing air from the bag; inserting the bag accommodating the elastic body into a cavity of the roller body; and taking air in the bag so as to expand the elastic body so that the cavity is filled with the bag accommodating the elastic body.
