'''Abstract''':
a gear device according to the disclosure includes an internal gear having a pin groove, a pin rotatably supported by the pin groove, an external gear oscillatorily rotating while its external tooth is engaging with the pin, and a speed reduction unit. the speed reduction unit decelerates a rotational driving force of an electric motor and transmits the decelerated rotational driving force to a rotating drive unit. the speed reducer includes a first reduction unit disposed on the input side and a second reduction unit disposed coaxially with the first reduction unit on the output side. a gap is formed between the external gear and the pin when the center of the pin groove, the center of the pin, and the tooth bottom of the external gear are aligned. the first gap in the first reduction unit is larger than the second gap in the second reduction unit.
