PROBLEM TO BE SOLVED: To provide a roller retainer for hardly causing the skewing of rollers while managing a circumferential gap therebetween. SOLUTION: The roller retainer 8 is laid between the rollers 1. It comprises a pair of roller contact parts 2 each having a curved recessed portion 2d corresponding to the outside shape of the roller 1, a connection shaft 3 for connecting the pair of roller contact parts 2 to each other so that the pair of roller contact parts 2 can approach/separate each other, and a coil spring 4 arranged between the pair of roller contact parts 2. The roller retainer is set between the rollers 1 to apply pressure to the rollers 1. The pressure prevents the skewing of the rollers 1 when inclined. COPYRIGHT: (C)2007,JPO&INPIT
