A geared motor includes a stopper mechanism restricting the range of movement when the trailing gear rotates in a counter-clockwise direction. In the stopper mechanism, a first and a second angle ranges are obtained by dividing the range of angle of rotation of the trailing side gear by a virtual line passing through the center of rotation of the trailing side gear and the center of rotation of the driving side gear. In the first angle range in which the stopper touching part moves in a direction approaching the center of rotation of the driving side gear when the trailing side gear rotates in a counter-clockwise direction, the stopper touching part touches the part to be touched by the stopper. Thus, when the stopper mechanism is activated, the trailing side gear is subjected to a reaction force in a direction away from the driving side gear, making the meshing shallower.

The geared motor and pointer device are provided with a stopper mechanism which restricts the range of movement of the trailing-side gear when the trailing-side gear rotates in a counter-clockwise direction. In the stopper mechanism, the part to be touched by the stopper comprises a support-side protrusion which protrudes towards the center of rotation of the trailing-side gear, and the width dimension in the peripheral direction of the support-side protrusion is smaller on the inside in the radial direction than on the outside in the radial direction. As a consequence, even if the width in the peripheral direction of the support-side protrusion is increased to a certain extent in order to ensure strength, when the stopper mechanism is activated, the stopper touching part and the part to be touched by the stopper come into contact at a position close to the center of rotation of the trailing-side gear.

A system for stopping rotation of a first gear and a second gear on a shaft, The first gear and second gear are concentric and rotatable about said shaft. The first gear and the second gear are driven by the same input system and the first gear and the second gear are configured to rotate at differential speeds and independently to each other. The first gear comprises a first end stop and the second gear comprises a second end stop and the first end stop and the second end stop are configured to engage each other when the first gear and the second gear have each rotated a predetermined number of turns. Engagement of the first end stop with the second end stop is configured to prevent rotation of the first gear and the second gear and cause a stall in the system.

An adjustable electric actuator system includes an actuator output, a compliance element coupled to the actuator output, and an end fitting element encapsulating at least a portion of the compliance element, wherein the compliance element is guided a first distance in a first axial direction by the actuator output, the first distance being limited by a first limitation element.

Latching motion transfer arrangements may be used to raise an object up and out of the engagement with the ground or other support surface and to lower the object back onto the ground or other support surface. In one exemplary embodiment, the mechanism is caused to lift and latch by applying force in a first direction, a first time, and is caused to release and lower by applying force in the first direction, a second time.
