PURPOSE:To lengthen a lifetime by pushing a plurality of rollers supported by a bearing against a stator, from which progressive waves are generated, by a presser. CONSTITUTION:A shaft 8' for a rotating body 8 is supported by a bearing, and rollers 10 are rotatably supported respectively by bearings to a plurality of support shafts 9 fixed to the rotating body 8 with inclination respectively. Consequently, the upper sections of the rollers 10 are tilted toward the inside and the rollers 10 are mounted to the support shafts 9, and the internal edges of the rollers 10 are brought into contact with a stator 11. A pushing body 12 set up to the upper sections of the rollers 10 is supported to a case so as to push the external edges of the rollers 10. Accordingly, when the stator 11 generates progressive waves, the rollers 10 are rolled on the end face of the stator 11 and forward moved while being rolled and made to progress on the underside of the pushing body 12, thus turning the rotating body 9. |
