Abstract
An elevator car (1) which moves vertically along the hoistway is provided with a roller guide assembly (3) guided by a guide rail (2). The roller guide assembly (3) is provided with a horizontal fixing shaft (8) which is fixed to a base member (6) and rollers (5a, 5b, 5c) which are supported by the horizontal fixing shaft (8). The rollers (5a, 5b, 5c) are each provided with a roller outer circumference section (10), a rolling bearing (9), an annular rubber (11), and an inner cylinder (12). The configuration eliminates the need for a conventional spring or a conventional damper mechanism because the rubber (11) deforms elastically.
