ABSTRACT:
An open type metal cord has a plurality of cord units each constituted by at least one preformed metal wire member. The wire members within a given cord unit have the same preforming ratio but have a different ratio from that of the wire members within another cord unit. A difference between the largest preforming ratio and the smallest preforming ratio in cord units falls within the range of 0.20 to 0.40. In this case, the maximum preforming ratio possible for the wire members is 1.65 and the minimum preforming ratio possible for the wire members is 1.05. A total number of wire members constituting a metal cord according to the present invention is 3 to 5.
