An auxiliary apparatus and a vehicle, which relate to the technical field of automobiles. The auxiliary apparatus includes: a base body having an accommodation cavity, the accommodation cavity having an open end; an auxiliary mechanism (2) disposed in the accommodation cavity; a cover body (3) movably disposed at the open end and movable relative to the open end between an open position and a closed position, the cover body (3) being entirely accommodated in the accommodation cavity when the cover body (3) moves from the closed position toward the open position; and at least one power mechanism disposed in the accommodation cavity, one of the at least one power mechanism being used for driving the auxiliary mechanism (2) to extend and retract through the open end. The auxiliary apparatus can prevent the auxiliary mechanism (2) and the cover body (3) from being extended together, and prevent the auxiliary apparatus from generating large wind resistance and wind noise when it is used.

The invention relates to a pump (1) having an electric motor (2), which has a rotor (3) and a stator (5) surrounding the rotor, which stator is injection-molded with a plastic housing (4) and has an end-side opening (6), having a circuit board (7), which closes the end-side opening (6) in a sealing manner and, together with the stator (5), defines an interior space (9) through which a cooling fluid can flow, the rotor (3) is arranged in the interior space. The key point of the invention is that an elastic seal (10) is arranged between the plastic housing (4) and the printed circuit board (7), and at least two fastening elements (11) are arranged on the end face of the plastic housing (4), which fastening elements are connected to fastening contours on the printed circuit board (7).
