題があった。A typical transmission device is a pair of pulleys (or sprockets) and a belt (chain).
However, in the above technique, since the circulation passage 4 is essential, the number of parts increases. Further, when the circulation passage 4 is made of rubber such as a high pressure hose, the environment resistance is poor, it cannot be used particularly in oil, and lubrication is likely to be incomplete. If the lubrication is incomplete, the wear of the parts will be severe due to the contact between the pulleys 2 and 3 and the mover 5 and the contact of the mover 5 in the circulation passage 4. Further, since the contact area between the moving element 5 and the driving pulley 2 and the driven pulley 3 is small, the surface pressure of the contact surface is high, and there is a problem that these parts are easily worn.

摩耗性が向上する。The present invention has the following effects due to the above configuration. According to a first aspect of the present invention, there is provided an endless belt-shaped member corresponding to a string of beads and a moving piece corresponding to a string of beads, and a base portion for engaging these moving pieces with the belt-like member, and integrally projecting from the base portion. It is characterized in that it is composed of a convex portion that meshes with the pocket portion of the pulley. Since the moving piece is composed of a base portion that engages with the belt-shaped member and a convex portion that integrally projects from the base portion and meshes with the pulley pocket portion, the contact area between the convex portion and the pulley pocket portion is increased. It is possible to suppress the respective surface pressures at the time of meshing, so that the wear resistance is improved.

By omitting the convex part from the moving piece, the piece consisting only of the base is a flat piece,
Since the flat piece is appropriately interposed between the moving pieces, the power transmission body can be lightly manufactured when a large transmission force is not required, and the weight reduction can prevent the power transmission body from fluttering. . In addition, it can be manufactured at low cost.
