Claims

[Scope of utility model registration request]

A pair of pulleys having V-shaped grooves whose spacing is controllable, a substantially V-shaped block forming both side edges that contact the pulley grooves and having an opening in the center, and a block that is connected to the opening of the block. A chain is constructed by connecting the links, which are inserted so as to fit together and support the blocks at intervals in the length direction of the belt, and are arranged so as not to contact the blocks in the length direction of the belt. 1. A continuously variable transmission, comprising: a pin supporting the pulley; the block forming a pin supporting portion projecting in the longitudinal direction of the belt;
