Claims

[Scope of utility model registration request]

Power transmission blocks are arranged adjacent to each other in a daisy chain on an endless carrier formed by stacking a plurality of belt-shaped hoops, and the endless carrier is frictionally engaged with the endless carrier retaining surface formed on the power transmission block. An endless belt for power transmission configured to transmit power together,
□The hoop of the endless carrier on the side that frictionally engages with the endless carrier retaining surface of the power transmission block is formed as a composite hoop in which a core material of a metal material is surrounded by resin,
and an endless for power transmission characterized in that the surface opposite to the surface that contacts the endless carrier engagement surface of the composite hoof is formed in a shape that is more convex at both ends than at the center in the width direction. belt.
