    Research output: Patent


    A rotary drive has a gear sector 120 in mesh with a drive pinion (110, fig 5). A member (140, fig 2) is mounted for rotation coaxially of the gear sector 120, spring means 148 being mounted on one of the gear sector 120 or member and abutment means 134,146 on the other of the gear sector 120 or member engaging the spring means 148 to bias the member to a central position relative to the gear sector 120. The spring means applies a restoring force towards the central position upon relative movement of the member 140 with respect to the gear selector 120 and stop means 154 is provided to limit relative movement in either direction. The member is drivingly connected to an output shaft 80. The spring means 148 may be U-shaped.
