    摘要： In a legged mobile robot (10) having a motor (42) that rotates the ankle joint (26R (26L)) about a right-and-left axis of the robot (26RY (26LY)) and a speed reducer (58) that reduces speed of an output of the motor, wherein the motor is disposed at a same position as the knee joint (22R (22L)) or at the thigh link (16R (16L)) such that the speed reducer is disposed at the shank link. With this, it becomes possible to reduce the weight of the distal end of the leg (12R (12L)) can be reduced, whereby enabling to reduce the inertial force generated in the leg during movement or locomotion of the robot.

    摘要： Vibrations of rotary shafts, such as shafts of cutting tools used in high speed machining, are reduced by damping structures in holes in the shafts. The damping structures comprise fingers that are urged outwardly by centrifugal force due to rotation of the shafts and that slide relative to adjacent shaft surfaces due to shaft vibrations, so that vibrational energy is absorbed frictionally. Chatter, a self-excited vibration of a cutting tool, can be substantially reduced in this manner.
