A device for limiting rotary movement in two directions comprising a housing (18) having a wall (17). A first stationary component (10) is attached to the wall (17) of the housing (18), the first stationary component having an arcuate segment (11) defined by lateral surfaces (11a, 11b) limiting the arc length thereof. A shaft (14) is rotatably mounted in the first component (10). A second component (20), also having an arcuate segment (21) defined by lateral surfaces (21a, 21b) limiting the arc length therof, is attached to the shaft. The first and second components (10, 20), respectively, have the same shapes and sizes and each of them is provided with a bearing (12, 22) which defines a bore (12a, 22a) and is molded on the arcuate segment (11, 21). Pins (11c, 21c) are positioned, respectively, to extend from oppositely directed faces of the arcuate segments (11, 21). The lateral surfaces ( 11a, 11b; 21a, 21b) of the first and second components (10,20) form abutments acting on both sides. |
