1. An electromechanical brake booster (100) for a vehicle, comprising:
an actuating unit (106), which can be coupled to a brake cylinder (200), wherein the actuating unit (106) has at least one actuating element (120), which can be coupled to an electric motor (102) by means of a gear mechanism (104), and at least one actuating member (124) having a recess (180) for receiving a force input member (128);
at least one housing (130), in which at least a section of the actuating unit (106) is accommodated; and
at least one damping element (132) through which the force input member (128) extends, which is arranged between the at least one housing (130) and the at least one actuating element (120), wherein the at least one damping element (132) is arranged between the at least one housing (130) and the at least one actuating element (120) in the direction of a longitudinal axis (L) of the brake booster (106) for preventing contact between the at least one actuating element (120) and the at least one housing (130);
the at least one damping element (132) having a damping section (156) and a fastening section (158), which holds the at least one damping element (132) on the at least one housing (130), the fastening section being tubular and the damping section being annular and extending outward from the fastening section.
