摘要： Since a mounting member 11 has a cylindrical surface 11h to be engaged with a cylindrical hole 4d, it is possible to position a mounting member 11 and a nut 4 by only engaging the cylindrical surface 11h with the cylindrical hole 4d. Accordingly, it is possible to easily perform an assembly. In addition, when a force is applied to the mounting member 11 from the guide groove 1e of the case 1 in the rotational direction of the nut 4, the force is partially applied to the cylindrical hole 4d. Therefore, it is possible to reduce a load applied to screws 12 that fix the mounting member 11, and to use thinner screws.
摘要翻译：由于安装构件11具有与圆筒孔4d接合的圆柱形表面11h，所以可以通过仅将圆柱形表面11h与圆柱形孔4d接合来定位安装构件11和螺母4。因此，可以容易地进行组装。此外，当从螺母4的旋转方向从壳体1的引导槽1 e向安装构件11施加力时，力部分地施加到圆筒孔4d。因此，可以减少施加在固定安装构件11的螺钉12上的负载，并且使用较薄的螺钉。

摘要： Since centers of a second gear, a fourth gear and a sixth gear coincide with each other and are disposed rotatably round a circumference of the same long shaft, a compact configuration can be realized while using a gear train of five gears to obtain a reduction gear ratio of a high gear ratio. The configuration in which the three gears have the same rotational center shaft in the way described above in an actuator which incorporates a plurality of gears is advantageous in that the number of center shafts is reduced and that the number of supporting holes in a housing which support center shafts is reduced.
摘要翻译：由于第二齿轮，第四齿轮和第六齿轮的中心彼此一致并且可旋转地设置在同一长轴的圆周上，所以可以在使用五档齿轮系的同时实现紧凑的结构，以获得减速齿轮高档比的比例。在包括多个齿轮的致动器中，三个齿轮具有与上述相同的旋转中心轴的构造的优点在于，中心轴的数量减少，并且壳体中的支撑孔的数量支撑中心轴减少。

摘要： A swinging actuator has an output shaft rotatably supported by a support member, a driving source for rotate-driving the output shaft, and an output arm, whose base end portion is connected and fixed to an end surface of the output shaft. A portion to be driven is driven by the end portion of the output arm. The swinging actuator comprises a screw hole provided in a portion, which is positioned off the center of rotation of the output shaft, a through hole formed in the base end portion of the output arm, a connecting screw screwed into the screw hole in a state in which the connecting screw is inserted into the through hole, and an engagement portion provided between a part, which is positioned off the through hole and in the end portion of the output arm, and a part, which is off the screw hole and in the end surface of the output shaft.

摘要： A portion of an outer face 41a installed with a second electric motor 18b is recessed more than a portion of projecting a switch shaft 2a. By the constitution, an outer diameter D18 of the shifting electric motor 18b is increased while ensuring a rigidity of a switch shaft 2a by restraining an amount of projecting the switch shaft 2a. Further, swift and firm gear change operation is made to be able to carry out by increasing an output of the shifting electric motor 18b.

摘要： An electric driving device for a transmission can be reduced in size with a simple structure, and can be installed in a small-sized car, such as a passenger car. In this electric driving device, a shift shaft 2 effects a selecting operation by its displacement in the axial direction and a shifting operation by its rotation. The displacement of the shift shaft 2 in the axial direction is effected by rocking and displacing a rocking arm 18 by means of a first actuator 13 or 113. Rotation of the shift shaft 2 is effected by pushing and/or pulling a rocking arm 20 by means of a second actuator 21. This driving arm 20 is fixedly disposed on the outer peripheral surface of a spline tube 5 which is brought into spline-engagement with the shift shaft 2.
