Abstract

L'objet de la présente invention concerne la réduction du bruit de fonctionnement d'un dispositif de servodirection électrique à un coût réduit, et l'amélioration de la fiabilité de la fixation d'un matériau absorbant acoustique par une structure simple. Le dispositif de servodirection électrique (1) comprend un moteur électrique (10) comportant un carter moteur (11), un dispositif de commande (31) pour commander le moteur électrique (10), un boîtier (32) dans lequel le dispositif de commande (31) est disposé, un matériau absorbant acoustique (60) disposé sur la périphérie extérieure du carter moteur (11) et un élément de fixation (70) pour maintenir le matériau absorbant acoustique (60) depuis l'extérieur, et l'élément de fixation (70) étant fixé au boîtier (32).
