Abstract
Elements of a transmission belt wound around pulleys of a continuously variable transmission each include a body part, a pair of pillar parts, and a pair of side surfaces. The pair of side surfaces each include a first side surface formed on a corresponding one of the pillar parts; and a second side surface formed so as to continue from the first side surface, and located more on an inner circumference side than the first side surface. A pair of the first side surfaces each are formed so as to be inclined toward an inner side of a corresponding one of the pillar parts with respect to an extending direction, from an inner circumference side to an outer circumference side of a ring, of a corresponding one of the second side surfaces continuing from the first side surface, and a pair of the second side surfaces is formed such that the second side surfaces are spaced farther apart from each other as the second side surfaces extend from the inner circumference side to the outer circumference side, and that an angle formed between the pair of the second side surfaces is larger by 0.2 to 0.8 degrees than an opening angle of V-shaped grooves of the pulleys.
