<P>PROBLEM TO BE SOLVED: To provide a planetary roller type traction drive which can detect the generation of a fine crack, can take measures in an early stage, and is high in reliability. <P>SOLUTION: The planetary roller type traction drive includes a plurality of planetary roller 5 which are arranged around a sun roller so as to be able to rotate/revolve, and a ring roller 7 which is arranged outside the plurality of planetary rollers 5 and sandwiches the planetary rollers 5 together with the sun roller. The planetary roller type traction drive is also characterized by being coated with a stress-coated membrane 35 (detection member) which detects the generation of the fine crack at the ring roller 7. <P>COPYRIGHT: (C)2012,JPO&INPIT |
