A chokeis provided for suppressing radio-frequency interference of a brush-type motor. The choke includes a single wire having a portion wound about a coil axis A to define a plurality of coilsincluding two outermost coilsand. An attaching structureextends from one of the outermost coils and includes a loop structure. The loop structure is constructed and arranged to be inserted into a slotin a brush cardand moved into hooked relation with a retaining memberof the brush card that is associated with the slot so as secure the choke to the brush card. At least a portion of the attaching structure is constructed and arranged to be in electrical connection with a brushof a motor when the choke is secured to the brush card. An elongated end portionof the choke extends directly from the other of the outermost coils. The elongated end portion is constructed and arranged to be directly electrically connected to an electrical connectorwhen the choke is secured to the brush card.
