Claims

[Claims for Utility Model Registration] ° 1 A V-belt constructed by alternately connecting two types of blocks with pins each having slopes corresponding to the pulley grooves on both sides, each of which When the slope of one V block is placed at the intermediate position, the slope of the other ■ block is placed at the position of each pin. A V-belt, characterized in that the distance between the slopes on both sides of the block is larger by a predetermined amount than the distance between the slopes on both sides of the one block located at intermediate positions between the pins. 2 The predetermined amount is 2(r'--r'"-P"/4
) - tanO12 (where P is the distance between each pin, θ is the angle formed by the slopes on both sides of the block, and r' is approximately the median value of the variable range of the pitch circle radius of the pulley). V-belt as described in Range 1. The V-belt according to claim 1 or 2, wherein either one or both of the 32 types of V-blocks is constructed by overlapping block pieces in the width direction. 4. The V-belt according to claim 3, in which part of the block pieces is formed of an elastic material.
