Document Type and Number:
Japanese Patent JP6908830
Kind Code:
B2
Abstract:
A power generator includes an operating portion (51); a first rotating member (62) rotated by external force applied to the operating portion (51), a second rotating member (63) which is able to rotate in the same direction as the first rotating member (62). An elastic member (65) is coupled to both the first rotating member (62) and the second rotating member (63) able to store energy when the first rotating member (62) is rotated and to release the stored energy to rotate the second rotating member (63). A magnet assembly on a toothed wheel is engaged with the second rotating member (63) and rotates together with it. A coil assembly (67) including a coil and a coil core inserted into the coil with two end portions. A magnetic torque is generated between the rotating magnet assembly (66) and the coil core.
