Abstract
An Oldham coupling includes a first coupling part, a second coupling part and an intermediate part. The first coupling part and the second coupling part are coupled to each other with the intermediate part provided therebetween. The first coupling part and the second coupling part are fitted on fitting portions of the intermediate part extending perpendicular to each other. The first coupling part, the second coupling part and the intermediate part have fitting indication portions. The fitting indication portions allow a positional relationship between the first coupling part and the second coupling part about a rotational axis to be determined.
