A power generation device (10) comprising a rotation member (1) rotatable by an operation force and a supporting member (2a, 2b) supporting the rotation member (1) by attracting the rotation member (1) with a magnetic force, the power generation device inducing a current to a coil by a magnetic flux of a magnet caused by rotation of the rotation member (1), and where, when the operation force is applied in a first state in which the rotation member (1) is supported by the supporting member (2a, 2b) by being attracted to a first and second portions of the supporting member (2a, 2b) at respective first and second positions, the rotation member (1) transitions to a second state by rotating with the first position of the supporting member (2a, 2b) as a first supporting point, and further transitions to a third state by rotating with a position of the supporting member different from the first position as a second supporting point. |
