摘要： The present disclosure relates to a manufacturing method of a speed reducer. The speed reducer includes an outer tube, a shaft portion, an input shaft, a first bearing, a speed reducing portion, and an attachment member. The shaft portion has a first receiving surface and a shaft end surface. The outer tube has a second receiving surface. The first bearing has a first inner ring and a first outer ring. The first receiving surface contacts the first inner ring. The second receiving surface contacts the first outer ring. A first machining accuracy is obtained based on a first parallelism between the first receiving surface and the shaft end surface. A second machining accuracy is obtained based on a second parallelism between the second receiving surface and the flange mounting surface. The manufacturing method includes performing machining such that the first machining accuracy becomes higher than the second machining accuracy.

摘要： A conductive particle detecting device includes a plurality of electrodes, a permanent magnet, and a detecting circuit. The plurality of electrodes are arranged at intervals in a lubricant. The permanent magnet accumulates conductive particles in the lubricant between adjacent electrodes by a magnetic force. The detecting circuit detects target conductive particles based on electrical resistance between the adjacent electrodes. An attractive force of the permanent magnet acting on the conductive particles between the adjacent electrodes is set such that the lubricant remains as a non-conductive layer around fine-sized conductive particles having a smaller particle size than the target conductive particles.

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 joint according to one aspect of the disclosure includes: a joint body having an input gear meshing with a speed reduction mechanism, the joint body receiving an output shaft of a motor detachably coupled to the joint body; a motor flange disposed between the speed reduction mechanism and the motor and rotatably supporting the joint body; and an intermediate flange connecting between the motor flange and the motor. At least one fixing member for fixing the joint body and the output shaft to each other is provided at at least one position in the joint body that overlaps with the intermediate flange as viewed from a radial direction. The intermediate flange is formed as an annulus surrounding the joint body by a plurality of split pieces that can be split in a circumferential direction.
