<P>PROBLEM TO BE SOLVED: To achieve a structure, with which repair and replacement work can be easily performed when an annular roller is damaged, in a friction roller type speed reducer of a type in which the annular roller rotates. <P>SOLUTION: The annular roller 5b and an output shaft 3b are connected with a connection bracket 30 to enable synchronized rotation. A holding tube part 32 of the connection bracket 30 is disposed around the annular roller 5b. The holding tube part 32 and the annular roller 5b are coupled enabling torque transmission, by engaging a recessed part 35 formed on an inner circumferential surface of the holding tube part 32 and a protrusion 37 formed on the outer circumferential surface of the annular roller 5b. Further, a retaining ring 43 prevents the annular roller 5b from exiting from the holding tube part 32. <P>COPYRIGHT: (C)2013,JPO&INPIT |
