Abstract: A drive unit includes an output shaft, a drive source, which causes the output shaft to rotate in a reciprocating manner within a first angular range, an arcuate movement portion, which performs arcuate movement about the axis of the output shaft as the shaft is rotated, a pivot shaft, and a lever member, which is rotational about the axis of the pivot shaft. As the arcuate movement portion performs arcuate movement, the lever member is rotated, in a reciprocating manner within a second angular range, while changing the engaging position with the arcuate movement portion.

Abstract: A sectoral reduction gear is arranged between a motor portion and a link mechanism. The sectoral reduction gear rotates in a reciprocating manner in a predetermined angle range on the basis of a forward rotation and a reverse rotation of the motor portion. An outer periphery of the sectoral reduction gear defines an imaginary circle. An inner region of the imaginary circle has an operating range in which the sectoral reduction gear, which rotates in a reciprocating manner, passes, and a non-operating range, in which the sectoral reduction gear does not pass. As seen from an axial direction of an output shaft, a part or the whole of the output shaft is arranged in the non-operating range.
