Abstract
A friction transmission belt has a rubber layer forming a pulley contacting portion. The rubber layer is made of a rubber composition containing a crosslinked rubber component and crosslinked polyolefin particles. Examples of the crosslinked polyolefin particles can contain ultrahigh molecular weight polyolefin particles having an average molecular weight of 500,000 or more.
