Abstract
In a high load transmission V-belt, a plurality of blocks 20 are attached and fixed to a tension band 10 extending in a belt length direction in a state in which each of the blocks 20 are arranged so as to sandwich an engagement section 18 of the tension band 10 in an inter-beam clearance portion 26 formed between upper and lower beam portions 23, 24. An increased amount of change ΔT in dimension T of the engagement section 18 of the tension band 10 in a belt thickness direction due to thermal expansion is equal to or less than an amount of change ΔG in dimension G of the inter-beam clearance portion 26 of the block 20 in the belt thickness direction while running the belt (ΔT≦ΔG).
