Abstract:
1. A motor device comprising: a motor portion having a link mechanism drivingly coupled to the motor portion, the link mechanism being integrally assembled in the motor portion; a sectoral reduction gear arranged between-the motor portion and the link mechanism, the sectoral reduction gear rotating in a reciprocating manner in a predetermined angle range on the basis of the forward rotation and the reverse rotation of the motor portion, the sectoral shape of the sectoral reduction gear having a size corresponding to the reciprocating rotation of the sectoral reduction gear, the sectoral reduction gear having the outer periphery being part of a representative circle, and an inner region of the representative circle having an operating range, in which the sectoral reduction gear rotating in a reciprocating manner in the predetermined angle range passes, and a non-operating range, in which the sectoral reduction gear does not pass; and an output shaft that is rotated in a reciprocating manner by the link mechanism, a part of or the whole of the output shaft being arranged in the non-operating range as seen from an axial direction of the output shaft.
