    • A remote controlled actuator includes an elongated spindle guide section and a distal end member fitted to a distal end thereof for alteration in attitude. The distal end member rotatably supports a spindle for holding a tool. The spindle guide section includes a rotary shaft for transmitting rotation of a tool rotation drive source to the spindle. An attitude altering member inserted in a guide hole is selectively advanced or retracted by an attitude control drive source. An initial attitude hold control unit controls the attitude control drive source so that an initial attitude holding force necessary to maintain the distal end member in the initial attitude can be applied to the attitude altering member. An attitude alteration control unit controls the attitude control drive source so that the attitude of the distal end member can be altered by a force larger than the initial attitude holding force.
    • 远程控制致动器包括细长主轴引导部分和安装到其远端的远端部件,用于改变姿态。 远端构件可旋转地支撑用于保持工具的心轴。 主轴引导部分包括用于将工具旋转驱动源的旋转传递到主轴的旋转轴。 插入引导孔中的姿态改变构件通过姿态控制驱动源选择性地前进或后退。 初始姿态保持控制单元控制姿态控制驱动源,使得能够将姿势改变构件应用于将前端构件保持在初始姿态所需的初始姿态保持力。 姿态改变控制单元控制姿态控制驱动源,使得可以通过大于初始姿态保持力的力来改变远端构件的姿态。

    • An output member is connected with an input member through three sets of link mechanisms for alteration in attitude. The link mechanism includes end portion link mechanisms on an input side and an output side, respectively, and an intermediate link member. The link mechanism is such that a geometric model of each of the link members expressed by lines represents such a shape as an input side portion and an output side portion relative to a center of the intermediate link member are symmetrical with each other. By actuating two or more sets of the link mechanisms by means of a link mechanism drive source, the attitude of the output member is controlled. Through the inside of an arrangement of the link mechanisms, a flexible wire is provided for transmitting a rotational force in a direction of arrangement of the input and output members.

    • A flexible wire assembly of a compact structure that can transmit the torque for a high speed rotation even in a bent condition is provided. The flexible wire assembly (A) includes a flexible outer tube (1), in which a flexible inner wire (2) having its opposite ends defining rotation input and output ends (2a and 2b), respectively, is rotatably supported by means of a plurality of rolling bearings (3). Spring elements (4I and 4O) are employed for applying preloads to those rolling bearings (3). The use is also made of a speed reducing mechanism (22) for reducing in speed and outputting rotation of the inner wire (2). The spring elements (4I and 4O) includes inner ring spring elements (4I) and outer ring spring elements (4O) that are alternately arranged over the length of the inner wire (2).
