<P>PROBLEM TO BE SOLVED: To provide a rolling roller driving mechanism capable of easily phase-adjusting a rolling roller in a rolling machine used for manufacturing a stepped member, a step part such as a groove, etc. is formed on the outer surface thereof. <P>SOLUTION: The rolling roller driving mechanism that rotationally drives a pair of rolling rollers includes drive shafts 17 and 18 connected to each rolling roller, rotary members 27 and 28 connected to the drive shafts and a relative position varying device 30 which varies relative positions of these rotary members. At least one of the rotary members is driven by the driving mechanism. The rotary members are so connected as to rotate at a constant speed in directions reverse to each other, and further, so constituted that, when the relative positions of these rotary members have varied, relative rotary phases of these rotary members vary. <P>COPYRIGHT: (C)2013,JPO&INPIT |
