Abstract

PURPOSE: To improve mechanical strength of a collector shoe by a method wherein a current collecting face is formed with a porous sintered material like aluminum, and the current collecting face is strengthened with a reinforcement.
CONSTITUTION: A plate reinforcement 2 is constituted with aluminum or its alloy, and a current collecting face 3 consisting of a porous sintered material is provided on the reinforcement. For member to constitute the current collecting face, aluminum particles 3a are combined in such degree as will come in contact with each other, and an aperture 4 is left between the particles so that a lubricant like graphite can be sucked and impregnated. A compound collector shoe is formed such, therefore the reinforcement and the current collecting face do not break away each other, a wear resistance of the current collecting face is improved, thus improving mechanical strength.
