A robot joint structure includes a first member and a second member that are hollow, an actuator that rotates the second member about a fourth axis relative to the first member, and a brake mechanism capable of braking rotation of the second member relative to the first member. The actuator includes a motor accommodated within the first member, a speed reducer that reduces the speed of rotation of a motor shaft of the motor and that transmits the rotation to the second member, a first gear provided at the motor shaft, and a second gear provided in the speed reducer and engaged with the first gear. The brake mechanism includes a brake body accommodated within the first member, a brake shaft capable of being braked by the brake body, and a third gear provided at the brake shaft and engaged with the second gear.
