Claims

[Scope of utility model registration request]

A driving device comprising a laminated endless metal band and a number of block pieces having lateral grooves supporting the metal band, and arranging the block pieces continuously along the entire length of the endless metal band via the lateral grooves. A plurality of convex portions are formed on one side of each of the block pieces, and a plurality of concave portions into which the plurality of convex portions can be individually fitted are formed on the other side, and the plurality of convex portions and the concave portions are connected to each other. 1. A driving device for a belt-type continuously variable transmission mechanism, characterized in that adjacent block pieces are sequentially connected to each other by fitting and arranged in rows on an endless metal band.
