Abstract
An elevator car () which moves vertically along the hoistway is provided with a roller guide assembly () guided by a guide rail (). The roller guide assembly () is provided with a horizontal fixing shaft () which is fixed to a base member () and rollers () which are supported by the horizontal fixing shaft (). The rollers () are each provided with a roller outer circumference section (), a rolling bearing (), an annular rubber (), and an inner cylinder (). The configuration eliminates the need for a conventional spring or a conventional damper mechanism because the rubber () deforms elastically.
