PURPOSE:To prevent that the most inner layer hoop of an endless carrier moves laterally, so as to make it possible to raise the durability of the hoops of the endless carrier, by forming engaging projections on one suface of the most inner layer hoop, and forming an engaging part which fits to the projections, on a power transmitting block. CONSTITUTION:Engaging projections 14 are formed as they project vertically, on both side lateral edges of the most inner layer hoop 11a of an endless carrier 11. These projections 14 of the hoop 11a are formed as they are placed on the lateral outside of the endless carrier engaging surface 13. In this constitution, the lateral movement of the hoop 11a is controlled, as the projections 14 are stopped by shoulders 13a of an engaging surface of the endless carrier. In this way, centering is performed accurately, and the durability of the hoops of the endless carrier is raised. |
