1. 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.

Abstract
An input disk and a clutch disk are supported by an output shaft in such a manner that the input disk is rotatable relative to the output shaft, and the clutch disk is non-rotatable relative to and is axially movable relative to the output shaft. When a large load torque is exerted about the output shaft, relative rotation between the input disk and the clutch disk occurs. A connecting rod has one end connected to a worm wheel, and is reciprocally swung through rotation of the worm wheel. A rotatable lever has one end, which is connected to the other end of the connecting rod, and has the other end, which is engaged with and is secured integrally with the gear teeth of the input disk.

6. A motor apparatus comprising:
-
a housing; an output shaft that is rotatably supported by the housing; a clutch device that includes; a gear member that is supported by the output shaft in such a manner that the gear member is 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; and a clutch disk that is supported by the output shaft in such a manner that the clutch disk is non-rotatable relative to the output shaft about the axis of the output shaft, wherein; the clutch disk is opposed to the gear member in an axial direction of the output shaft and is connected to the gear member in a manner that enables transmission of a drive force therebetween; when a load torque equal to or greater than a predetermined value is exerted about the axis of the output shaft, relative rotation between the gear member and the clutch disk occurs; 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 directly or indirectly 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. - View Dependent Claims (7, 8, 9, 10, 11, 12)
