An adjustable rear-view mirror, in particular exterior rear-view mirror for a motor vehicle, has a first element (1) that can be secured to the vehicle and a second element (2) swivelingly joined to the first element and which forms or includes a support for a mirror (4). The two elements (1, 2) are designed as shell-shaped elements (1, 2) at least partially nested into each other that slide upon each other over outer and inner delimiting surfaces which form a part of a spherical surface. A drive (6) is provided between the first and second elements (1, 2). According to the invention, the outer element (2) is provided at least partially on its inner surface with teeth which extend along a circle of the spherical inner surface of the outer element (2). A pinion (8) of a drive (6) mounted inside the inner element (1) to adjust the outer element (29 with respect to the inner element (1) engages the teeth. A simple structure is thus obtained which is largely insensitive to vibrations.

Ce rétroviseur ajustable, notamment rétroviseur extérieur, pour un véhicule à moteur, comprend un premier élément (1) qui peut être fixé au véhicule et un deuxième élément (2) relié pivotant au premier élément et qui forme ou qui contient un support d'un miroir (4). Les deux éléments (1, 2) ont la forme de coques (1, 2) qui s'emboîtent au moins partiellement et glissent l'une sur l'autre sur des surfaces externe et interne de limitation qui forment une partie d'une surface sphérique. Un mécanisme d'entraînement (6) est monté entre les premier et deuxième éléments (1, 2). Selon l'invention, la surface interne de l'élément extérieur (2) est pourvue au moins en partie d'une denture qui s'étend le long d'un cercle de la surface interne sphérique de l'élément extérieur (2). Un pignon (8) d'un mécanisme d'entraînement (8) monté à l'intérieur de l'élément intérieur (6) pour déplacer l'élément extérieur (2) par rapport à l'élément intérieur (1) engrène la denture, ce qui permet d'obtenir avec une structure simple un dispositif qui est largement insensible aux vibrations.
