Claim:
1. An actuator device for a rearview device of a motor vehicle comprising: at least one retaining element; at least one adjusting element which can be transferred into a plurality of functional positions comprising a basic position and at least one end position; at least one driving means which comprises at least one shape-memory element which is in the form of a wire and extends between the retaining element and the adjusting element and is secured to both, where the extension of said shape-memory element is modified on being actuated and by means of the modification of the extension of which the at least one adjusting element is transferred from one functional position into another functional position; at least one heat-conducting means which lies in contact with the driving means at least in the end position of the adjusting element; and at least one switching means, by means of which the at least one driving means and the at least one heat-conducting means are arranged with respect to one another with no contact in the basic position of the adjusting element and by means of which the at least one driving means and the at least one heat-conducting means are arranged touching one another at least in sections at least in the end position of the adjusting element; wherein the heat-conducting means is stationary and the driving means is moved transversely or obliquely to the extension of the driving means between the retaining element and the adjusting element by the switching means; and the switching means is configured as a joint component with the adjusting element and comprises a shaping of a surface section of the adjusting element, wherein the driving means lies in contact with a point of contact of the surface section of the adjusting element such that the driving means is positioned relative to the heat-conducting means as the adjusting element transitions from the basic position into the end position.
