PROBLEM TO BE SOLVED: To provide a robot provided with a small-sized shoulder joint in which rotary mechanisms are arranged in a plural number.SOLUTION: With regard to a robot 1 provided with a shoulder joint part 12, the shoulder joint 12 includes: a first rotary part 16 which rotates a first rotational axis 14c; a second rotary part 23 which is connected to the first rotary part 16 and rotates a second rotational axis 21c; and a third rotary part 25 which is connected to the second rotary part 23 and rotates a third rotational axis 26c. A center line 14a of the first rotational axis and a center line 21a of the second rotational axis intersect at a first intersection 22, the center line 21a of the second rotational axis and a center line 26a of the third rotational axis intersect at a second intersection 27, and the first intersection 22 and the second intersection 27 are apart. |
