A V-belt for high-load transmission, in which impact resistance of blocks is enhanced with separation of a contact section from a reinforcement member suppressed and without a reduction in transmission performance and wear resistance of the belt. The V-belt (B) for high-load transmission has at least one tension belt (10) endlessly extended in an annular shape and also has the blocks (20) engaged with and fixed to the tension belt (10) at predetermined intervals in the longitudinal direction of the belt. Each block (20) has a reinforcement member (27) and contact parts (28) that are formed of a resin on opposite sides, in the lateral direction of the belt, of the reinforcement member (27) and have contact surfaces (30) in contact with a pulley. The thickness (w) of each contact part (28) in the direction vertical to the contact surface (30) is not less than 1.0 mm but note more than 1.8 mm. |
