Abstract
To realize a high-performance, lightweight, and relatively simple structure for a compact generator. [Solution] This is a small generator 1 that converts rotational force rotating around a base axis J1 into electricity. It comprises a power generation member 80 that is arranged around the base axis J1 and generates electricity by rotating around a rotation axis J2 that is eccentric to the base axis J1, and a speed change member 50 that is arranged around the base axis J1 and is coaxially connected to the power generation member 80. The speed change member 50 increases the rotational speed of the rotational force and transmits it to the power generation member 80.
