The operating unit comprises an operating element which is adapted to be mechanically excited by means of a piezo driver. The piezo driver comprises a piezo actuator made from a piezoelectric material. The longitudinal extension ends of the piezo actuator have mechanically coupled thereto a conversion gear 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. The conversion gear comprises a first bracket which is of an elastic configuration and/or comprises an elastic material and which, in the area of the longitudinal extension ends of the piezo actuator, is mechanically coupled to the latter. The first bracket is provided with a first and a second end portion, where the first bracket is respectively mechanically coupled to the piezo actuator, and between the two end portions, is provided with an oblique first inclined portion and an oblique second inclined portion which is shorter as compared to the first inclined portion. These portions of the bracket extend like the sides of a triangle with an imaginary connecting line extending between the end portions of the bracket as a basis and are elastically connected to each other.
