PROBLEM TO BE SOLVED: To provide a rotating motion transmission device not transmitting a rotating motion when a high speed rotation is rapidly carried out.SOLUTION: A rotating motion transmission device 7 of this invention comprises: a cylindrical member 13 having an output shaft 11; a pair of first and second rod magnets 14, 15 arranged to face to each other while holding the output shaft; and an operating part 16 for alternatively separating the first and second rod magnets from the cylindrical member as an input shaft 9 is rotated. The outer peripheral surface of the cylindrical member have a plurality of magnets arranged from a starting point placed at a middle point of an axial length toward both ends at the opposite side while holding the output shaft and having polarity being set to cause an attracting force drawn toward both ends of the first and second rod magnets; and a plurality of magnets arranged from both ends toward the starting point at a side where a plurality of magnets are not present at the outer peripheral surface with their polarity being set to cause a repulsive force to act that they may move away from both ends of the first and second rod magnets. The cylindrical member is rotated once by the operating part to transmit a rotating motion of the input shaft to the output shaft.SELECTED DRAWING: Figure 2 |
