ABSTRACT

In a state where an output shaft of a fifth axis motor that allows a support
arm of a collaborative robot to rotate about the fifth axis is disposed along
a fourth axis, the fifth axis motor and a torque converter that converts a
torque of the output shaft into a torque about the fifth axis are housed
inside of an upper arm. The upper arm is a cylindrical case, and includes an
arm body having an opening for attaching the fifth axis motor and the torque
converter, and a cover attached to the arm body to cover the opening. The
fifth axis motor and the torque converter are housed in an internal region
within an opening edge of the opening when viewed along the fifth axis.
