Abstract
A driving-unit that rotates a first-member and a second-member constituting a robot-arm about a rotary-axis. The driving-unit includes: a bracket fixed to the first-member and including a first-hollow-hole penetrating along the rotary-axis; a motor fixed to the bracket and accommodated in the first-member; a reducer that connects the bracket and the second-member rotatable about the rotary-axis and that includes a second-hollow-hole penetrating along the rotary-axis; and a driving power transmission mechanism accommodated in the bracket and transmitting a rotation of the motor to the reducer. The driving power transmission mechanism includes a driving-shaft, a first-transmission-mechanism that transmits the rotation of the motor to the driving-shaft, and a second-transmission-mechanism that transmits a rotation of the driving-shaft to an input-shaft of the reducer. A distance between a shaft of the motor and the rotary-axis is shorter than a distance between the driving-shaft and the rotary-axis.
