Herein disclosed is a V-belt transmission device in which a plurality of substantially V-shaped metal members (2) and a plurality of resilient metal members (3) are alternately mounted to an endless metal belt member made of band steel and are in contact with each other to constitute a V-belt which is subjected to a tension between a driving V-pulley (5) and a driven V-pulley (6), thereby effecting a torque transmission between both the pulleys. Each of the V-shaped metal members (2) is provided with a substantially U-shaped groove (7) directed to the outside. Each of the resilient metal members is formed as a hollow roller to engage with recessed surfaces (8) which are formed in opposing surfaces of a pair of the V-shaped metal members (2). The V-shaped metal members (2) and the resilient metal members are fastened together at their outer peripheries by the metal belt member. The V-belt transmission device is characterized in that a pair of right and left engaging grooves (9) are formed at inward wall of arm end portions of each of the U-shaped grooves (7) formed in the V-shaped metal members (2) and stop members (10) are each formed in a plate having a narrow portion (10a) and at least one wide portion (10b), each of the stop members being engaged with the engaging grooves (9) with the narrow portion (10a).
