摘要： A copper alloy having an improved corrosion resistance in an alcohol-containing medium, which consists essentially of 0.5 to 8 weight percent tin and/or nickel alone or in combination, 0.02 to 0.15 weight percent zirconium, and remainder weight percent copper. The zirconium is dispersed in the copper alloy as precipitates. The copper alloy is suitable for a commutator material used in a DC motor having an improved abrasive resistance.

摘要： Miniaturizing a motor part of a fuel pump by miniaturizing an armature cover can be achieved. A brush assembling structure for fuel pump in which a brush is assembled into a brush holder of an armature cover so as to press one end surface of the brush to abut on a commutator by the other end surface of the brush, the brush assembling structure comprises: a power-supply shunt wire provided on one end portion of the brush; at least one shunt wire drawing groove formed on the one end portion of the brush and arranged in the circumferential direction with respect to a bearing hole of the armature cover; and a guide groove provided in the brush holder as corresponding to the shunt wire drawing groove, wherein a drawing direction of the shunt wire extending from the one end surface of the brush and being guided by both the shunt wire drawing groove and the guide groove is the circumferential direction. A power supplying terminal provided on an end portion of the shunt wire is arranged on approximately the same circumference as the shunt wire drawing groove.
