Abstract
A webbing for a safety belt includes a main part and selvedges extending along both sides of the main part. The denier size of warp threads in at least one of the selvedges is smaller than the denier size of warp threads in the main part and decreases stepwise toward the outermost warp thread in the selvedge. The outermost warp thread has a denier size either equal to or smaller than the denier size of weft threads. The weft threads are made of threads having a higher heat shrinkage percentage than the warp threads in the main part.
