    摘要： A gear device is provided with a carrier having a first member and a second member opposed to the first member in a rotation axis direction, a crankshaft configured to cause the carrier to rotate relative to an outer cylinder about a rotation axis, an insertion pin inserted into the first member and the second member, and a restriction member configured to restrict movement of the insertion pin. The insertion pin is housed in such a manner as to extend from a first hole over to a second hole, the first hole formed in the first member so as to extend through the first member, the second hole formed in the second member so as to correspond to the first hole. At least one of the first hole and the second hole has such a shape as to restrict movement of the insertion pin toward the second hole in the rotation axis direction. The restriction member is mounted in the first member so as to restrict movement of the insertion pin toward the first hole in the rotation axis direction.

    摘要： A speed reducer according to one embodiment of the present invention includes a crankshaft and a speed reducing mechanism. The crankshaft includes a gear portion driven by rotation from a drive source and a journal portion formed integrally with the gear portion. The crankshaft rotates about an axis of the journal portion. The speed reducing mechanism decelerates rotation of the crankshaft and outputs the decelerated rotation.

    摘要： One object is to provide a steering device that facilitates disengagement of a speed reducer so that, for example, when the speed reducer fails, the speed reducer can be disengaged to enable steering of a vehicle with a manual operational force alone. This application relates to a steering device provided with a steering mechanism and a speed reducer. The steering mechanism steers tires of a vehicle under a steering force from a steering wheel. The speed reducer is connected to a motor for outputting a steering assistance force corresponding to the steering force. The speed reducer enlarges the steering assistance force and transmits the enlarged steering assistance force to the steering mechanism. The speed reducer is connected to the steering mechanism via a speed reducer arm.

    摘要： A gear device is provided with inner-tooth pins fitted into pin grooves of an outer cylinder, a carrier housed inside the outer cylinder, a crankshaft rotatably supported on the carrier, an oscillating gear having outer teeth meshable with the inner-tooth pins and configured to oscillate in conjunction with rotation of the crankshaft, while the outer teeth are meshed with the inner-tooth pins, and a restriction member configured to restrict movement of the inner-tooth pins in an axial direction. The restriction member is mounted to the outer cylinder on an outer side of the outer cylinder.
