Abstract

A single-band type metallic belt wound between annular V-grooves of a drive pulley and a driven pulley is provided. The metallic belt includes a metal endless band having at least one layer, and a plurality of metal push blocks engaged and superimposed on the band in a manner enabling sliding in a longitudinal direction of the band. The push block includes a body formed by bending a single wire material and subsequently performing pressing so as to have two outer side surfaces defining side contact surfaces that are inclined to respectively make frictional contact with two inner surfaces of the annular V-grooves. A pair of pillars respectively extend along extensions of the two contact surfaces of the body and have an outer surface that is continuous with the side contact surfaces of the body. A pair of opposed hooks extend. The outer side surface of the push block that makes frictional contact with the V-grooves include an oil film breaking portion. An opening is defined by the pair of hooks, and a band holding surface is formed on the body in the opening. The band is inserted in the opening of each push block and held on the band holding surface. A metal retainer is arranged on an outer surface of the band in a manner engageable with the pair of hooks to ensure engagement between the band and the push blocks. A ring is attached to the outer surface of the retainer to prevent deformation of the retainer.
