A vehicle operating unit with tactile feedback upon manual actuation, comprising - a housing, - an operating element which is adapted to be manually actuated, and - a piezo driver for pulsed mechanical excitation of the operating element, - wherein the piezo driver is arranged between a housing wall of the housing and the operating element and provided with - a piezo actuator made from a piezoelectric material, wherein the piezo actuator is of a strand-shaped configuration and has a longitudinal extension between two ends and wherein the longitudinal extension of the piezo actuator defines the effective direction of the latter along which the piezo actuator expands and/or contracts when being driven, and - a conversion gear mechanically coupled to the longitudinal extension ends of the piezo actuator for converting a length change of the piezo actuator occurring in the effective direction of the piezo actuator into a movement of an element, which is coupled to the conversion gear and to be moved, at an angle not equal to 0 degree relative to the longitudinal extension of the piezo actuator, - wherein the conversion gear comprises a first bracket which is of an elastic configuration and/or comprises an elastic material and, in the area of the longitudinal extension ends of the piezo actuator, is mechanically coupled to the latter, characterized in - that the first bracket comprises a first end portion and a second end portion, within which the first bracket is respectively mechanically coupled to the piezo actuator, and between the two end portions (36, 38) an oblique first inclined portion and an oblique second inclined portion, that is shorter as compared to the first inclined portion, which extend like the sides of a triangle with an imaginary connecting line extending between the end portions (36, 38) of the bracket as a basis and are connected to each other, in particular elastically connected to each other, and where the first inclined portion is connected, in particular elastically connected, to the first end portion and the second inclined portion is connected, in particular elastically connected, to the second end portion, and - that the first bracket is coupled to the operating element and the piezo actuator is coupled to the housing wall, or the first bracket is coupled to the housing wall and the piezo actuator is coupled to the operating element. -
