Oxa(thia)zolidine compounds, process for preparation thereof and anti-inflammatory agents

A belt for a continuously variable transmission, which is wound around a drive pulley and a driven pulley for transmitting a driving force between both the pulleys, the belt comprising a metal ring assembly formed of a plurality of endless metal rings laminated one on another, and a large number of metal elements each having a ring slot into which the metal ring assembly is fitted,

• wherein said metal ring assembly is interposed between the radially outer edge of the ring slot and a saddle face of the metal element constituting a radially inner edge of said ring slot,
• wherein an endless resilient member which is elastically deformable radially is disposed between said radially outer edge of the ring slot and a radially outer peripheral surface of the metal ring assembly;
• and
• wherein a radial thickness of said endless resilient member is set smaller than a distance between the radially outer edge of each ring slot and the radially outer peripheral surface of the metal ring assembly when supported on the saddle face of the metal element and a shock to be acted from the metal element on the metal ring assembly during operation of the transmission is buffered by said resilient member being resiliently deformed in a radial direction.
