Abstract

See full text

The present invention relates to a brush type contact material, including one or more curved metal pawls of which ends come into contact with objects to be contacted. The ends of the pawls have an arc-like cross section in a thickness direction, a curvature radius R1 on a front side from a contact point with the object to be contacted and a curvature radius R2 on a back side from the contact point are formed so as to be R1≧R2, and also both ends in a width direction of the pawl are chamfered. At this time, preferably, R1 is larger than R2 (R1>R2), and R1 divided by R2 (R1/R2) is 3.0 or less. The brush type contact material according to the present invention enables a smoother sliding movement than ever before and can be relatively simply manufactured.
