Claims

[Claims for Utility Model Registration] An endless carrier stretched between pulleys having a circumferential groove with a V-shaped cross section, and an endless carrier that is supported adjacent to each other in a daisy chain so as to be able to move freely along the endless carrier. a plurality of power transmission blocks that are frictionally engaged with the circumferential groove on both sides and frictionally engaged with the endless carrier on a carrier engagement surface, and each power transmission block is connected to other power transmission blocks adjacent thereto. The power transmission block has a recess on one end face facing the pulley, and a protrusion on the other end face that fits into the recess of another power transmission block adjacent thereto, and in a region where the power transmission block is wrapped around the pulley in an arc shape. In the endless belt for power transmission configured such that the tip end face of the protrusion and the bottom face of the recess come into contact at substantially the same radial position as the carrier engagement surface, In addition to setting the height dimension larger than the depth dimension of the depression,
An endless belt for power transmission, characterized in that the distal end surface of the protrusion has a continuous shape consisting of a flat portion and a cylindrical surface portion located on the inner circumferential side.
