<P>PROBLEM TO BE SOLVED: To obtain a structure which can suppress chipping of a resin member caused by a shear force generated when a block receives a thrust force from a pulley, by devising the structure of a reinforcement member in the inner beam of the block, in a V-belt for high-load transmission having the block with the reinforcement member, at least, of which both ends in the belt width direction are covered with the resin member. Ž<P>SOLUTION: The V-belt B for high-load transmission includes tension belts 10 each formed in a ring shape, and two or more blocks 20, each having fitting parts 24 fitted with the tension belts 10 on the sides. The block 20 includes the reinforcement member 27 comprising beam parts 21 and 22 formed on the inner and outer peripheral sides of the fitting part 24, and the resin member 28 covering at least both ends of the reinforcement member 27 in the belt width direction. The reinforcement member 27 in the inner beam part 22 is provided with an enlarged cross section part 27a in which the cross-sectional area enlarges at both end sides in the width direction where the inner beam part 22 comes into contact with the pulley.
