Abstract
A robot joint structure includes a motor configured to be used for a robot joint shaft capable of turning about a vertical axis, a motor-side gear mounted on a shaft of the motor, an auxiliary bearing configured to axially support the shaft supplementally, an adapter configured to integrate the motor, the motor-side gear, and the auxiliary bearing, and a moving mechanism configured to move a unit structure integrated by the adaptor in a radial direction of the motor such that the motor-side gear approaches a mating gear meshing with the motor-side gear.
