摘要： A durable V-belt formed by fastening plate-like elements juxtaposed annularly using a ring. The element comprises a saddle face on which the ring is disposed, columns extending radially outwardly from lateral ends of a saddle face, and flank faces formed on lateral ends of the column to be contacted with a groove of a V-pulley to transmit power. An angle between outer circumferential portions of the flank faces is substantially identical to or smaller than an open angle of the groove of the V-pulley; and an angle between inner circumferential portions of the flank faces is larger than the angle between the outer circumferential portions.
