<p>PROBLEM TO BE SOLVED: To provide a new power transmission device capable of efficiently transmitting power from a motor to an output member via magnetic connection and hardly having trouble caused by abrasion between gears.SOLUTION: A power transmission device includes a pair of first magnets 10, a transmission mechanism 11 moving both of the first magnets 10 toward and away from each other by using a drive force from a motor 3, an output member 12 rotatably mounted between both of the first magnets 10, and a second magnet 13 mounted in the output member 12 and receiving a repulsive force in a rotation direction of the output member 12 from both of the first magnets 10 moving toward each other.</p> |
