The invention discloses a wear resistance detecting device for automobile accessories. The wear resistance detecting device for the automobile accessories comprises a base; a groove is formed in one side of the base; a first driving motor is mounted in the groove; an output shaft of the first driving motor is connected with an air bellow in a sleeving manner; the outer wall of the top of the air bellow is welded with an air guide pipe; a baffle plate which is welded perpendicular to the base is mounted at one end, far away from the air bellow, of the air guide pipe; a vent pipeline is arranged in the baffle plate in the height direction of the baffle plate; the vent pipeline communicates with the air guide pipe; a plurality of groups of vent holes which communicate with the vent pipeline are formed in one side of the baffle plate; a dust collecting groove is formed in the surface of the base; a supporting plate is vertically welded on the surface of the side, far away from the baffle plate, of the base; and a mounting groove is formed in the surface of the side, close to the baffle plate, of the supporting plate. The wear resistance detecting device for the automobile accessories is novel in design; debris on the surface of a component can be blown off in time; a detecting result is prevented from being influenced because of the increment of friction force between a friction mechanism and the component caused by the debris; the pressure on the component of a friction plate can be adjusted manually; and the wear resistance detecting device for the automobile accessories is beneficial to obtaining a detecting result.
