Abstract: A display device has a scale in the shape of a circular arc. On an axis driving an indicator axis, a rotatably mounted gear wheel is arranged in a rotatably fixed manner, in the teeth of which the toothing of a wobble gear ring partially engages. The wobble gear ring is mounted about the axis of the rotatably mounted gear wheel such that the wobble gear ring can wobble, is acted upon by spring forces distributed around the periphery of the wobble gear ring in the direction of engagement of the toothing of the wobble gear ring in the teeth of the rotatably mounted gear wheel, and is fixedly connected to a ferromagnetic ring extending in the direction of rotation of the wobble gear ring. At least two pole shoes project through independently energizable coils to the outer circumferential surface of the ferromagnetic ring.

Abstract: A display unit having a display module, which has a display having a rear display wall with bosses having support surfaces. A housing covers the of the display has support bosses through which fastening screws are guided and can be screwed into holes of the screw bosses to brace the display module against the housing. A spacer is arranged between each screw and support. The surface of the spacer extends parallel to the rear display wall. The spacer is supported on the support boss. The spacer surface and the supporting surface of the support boss rise helically in opposite directions and are concentric to a through-hole. The threaded shaft of the fastening screw protrudes through a spacer through-opening and is frictionally locked to the inner wall of the spacer through-opening to a certain torque.
