Abstract: PROBLEM TO BE SOLVED: To provide a transmission belt including a retainer ring which improves durability and which can achieve narrow width.SOLUTION: A plurality of elements 20 each of which includes a body part 21, a pair of pillar parts 22 and a pair of hook parts 23 are bound in an annular shape by a binding ring 11, and a retainer ring 12 is arranged on the radially outside of the binding ring 11. Then, in the pair of hook parts 23, a contact part 23b coming into contact with the retainer ring 12 radially inside is formed so as to be inclined to the radially outer peripheral side toward a tip part 23a.
