The present invention relates to a power generation device inserted between a frame (10) and a wheel (20) of a bicycle. The power generation device comprises: a magnetic plate (30) which is installed in the wheel (20) through a holder (32) and has multiple permanent magnets (34, 35) on the concentric circle thereof; and a generation body (40) which is installed in the frame (10) to face the magnetic plate and generates regulated power supply using induced electricity. Accordingly, the power generation device is able to be easily installed in a bicycle and satisfies costs, environment, and usability by reducing power loss caused by the contact and obtaining semi-permanent electricity. |
