<P>PROBLEM TO BE SOLVED: To provide a non-contact rotation type power transmission device, capable of contriving for lower cost and smaller size by assuring a core gap holding structure which can stably maintain a core gap between cores, facing each other, without affected by fluctuation such as loosening. <P>SOLUTION: The non-contact rotation type power transmission device 1 includes a bearing inner ring 80 which is secured to a fixed base 20 and holds one core as a fixed core 70, under such condition as cores 50 and 70 are faced each other. A movable base 10 includes a bearing outer ring 30 which is pivoted by the bearing inner ring 80 for free rotation. A sliding sheet 60 of non-magnetic body having a low friction coefficient is interposed between the opposed surfaces of the cores. It further includes a core presser 40, which is interposed between the opposed surfaces of a movable core 50 and the movable base 10 under such condition as the other core is stored in the bearing inner ring 80 as the movable core 50, with one end connected to the movable core 50 for detention while the other end, imparted with an energizing force along the opposing direction of the cores, connected, for detention, to the movable base 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
