An attachment structure for drive cables include a first fixing member and a second fixing member separate from the first fixing member, which are designed to fix the drive cables in a non-slidable manner. The first fixing member is disposed behind a pivot body of a robot so as to pivot together with the pivot body. The second fixing member is disposed so as to be spaced apart from the first fixing member in a direction parallel to a rotational axis of an arm of the robot. The drive cables are fixed so as to be convexly curved upward in a portion between the first fixing member and the second fixing member.
