| 摘要 |
The invention relates to a rotary/push operating device (10) for a man-machine interface, in particular for operating units of a vehicle, comprising a manually operably rotary/push element (12), which can be rotated about a rotational axis (15) and which can be pushed down in the direction of the rotational axis (15), and a rolling-element bearing (14), which defines the rotational axis (15) and which has a stationary bearing ring (18), a movable bearing ring (20), and a rolling-element cage (22) arranged between said bearing rings. The rotary/push element (12) is coupled to the movable bearing ring (20) in such a way that the rotary/push element (12) moves together with the movable bearing ring (20) when the movable bearing ring (20) rotates during rotation of the rotary/push element (12) or is axially moved in the direction of the rotational axis (15). |
