Abstract

A main cable of an elevator which comprises an inner layer portion (1) having a plurality of inner layer strands (2) and, arranged so as to cover the perimeter of the inner layer portion (1), an outer layer portion (4) having a plurality of outer layer strands (5), the inner layer strand(2) and the outer layer strands (5) being manufactured by twisting together elementary wires made of a synthetic fiber, wherein the outer layer portion (4) has a tensile strength lower than that of the inner layer portion (1). The inner layer portion (1) preferably has a tensile strength of 60 % or more relative to the total tensile strength of the main cable.
