Patent ID: 7673366

Claim:
A motor apparatus comprising: a housing; an output shaft that is rotatably supported by the housing; a gear member that is supported by the output shaft in such a manner that the gear member is non-rotatable relative to the output shaft about an axis of the output shaft, wherein the gear member has gear teeth along an outer peripheral part of the gear member to receive a drive force; a rotatable body that is rotatably supported by the housing; a motor main body that provides a rotational drive force for rotating the rotatable body; a connecting rod that has a first end, which is connected to the rotatable body at a point that is different from a rotational center of the rotatable body, and a second end, which is opposite to the first end, wherein the connecting rod is reciprocally swung through rotation of the rotatable body; and a rotatable lever that has a first end, which is connected to the second end of the connecting rod, and a second end, which is engaged with and is secured integrally with the gear teeth of the gear member to limit relative rotation between the rotatable lever and the gear member, wherein the rotatable lever reciprocally rotates the gear member about the axis of the output shaft through reciprocal swinging movement of the connecting rod, wherein; the second end of the rotatable lever includes a receiving portion, which receives an outer peripheral part of the gear teeth of the gear member; and at least one mating protrusion is formed in an inner peripheral surface of the receiving portion and is meshed with the gear teeth of the gear member.
