PROBLEM TO BE SOLVED: To provide a robot capable of reducing load torque of a motor and miniaturizing the motor. SOLUTION: A parallel link mechanism is constituted of an arm member A, a first link 1, a second link 2, and a third link 3, and the first link 1 and the third link 3 are coaxially and pivotally supported in a basic part 6. One end of a fourth link having a shorter link length than a link length of the third link 3 is pivoted on the second link 2 and the third link 3 by a pivotal shaft pivoting the second link 2 and the third link 3, and one end of a fifth link having the same link length as that of the fourth link 4 is pivoted on the other end of the fourth link 4. The other end of the fifth link 5 is pivotally supported in the basic part 6, and a rotary shaft of the motor M is connected with the pivotal shaft so that the fifth link 5 can perform the operation corresponding to the rotation of the motor M. |
