Claims

[Scope of utility model registration request]

A V-belt is created by stacking a plurality of metal endless belts and engaging a large number of V-shaped blocks along the belt in a connected manner, and having an inwardly inclined surface that contacts the outwardly inclined surfaces at both ends of the V-shaped blocks. In a continuously variable transmission in which the V-belt is stretched across a driving pulley and a driven pulley, which are composed of a pair of disks whose distance can be changed, the contact portion between the outwardly inclined surface of the V-shaped block and the inwardly inclined surface of the pulley disk is overlapped. A block of a V-belt for a continuously variable transmission characterized by being arranged at a position on the outer periphery of a laminated metal endless belt.
