摘要：
The invention relates to a piezoelectric drive device for adjusting movable parts (11), particularly in a motor vehicle, having a piezo motor (12) having at least one piezo actuator comprising an electric piezo element, wherein at least one friction element (30) is disposed on the piezo motor (12), said element interacting with a friction surface (14) of at least one guide rail (16) opposite said friction element (30) for creating a relative movement, wherein the friction surface is positioned opposite of the friction element (30), wherein the at least one piezo motor (12) is supported on a first side (94) of a bearing bracket (8) and a counter element (98) is disposed on a second opposite side (95) of the bearing bracket (8), which exerts a counter force (97) to the friction element (30) onto the at least one guide rail (16).
