PROBLEM TO BE SOLVED: To provide an Oldham coupling that prevents a phase shift when a rotary motor and a detector are connected mutually.SOLUTION: An Oldham coupling 10 is formed by a first coupling member 12, a second coupling member 14, and an intermediate member 16. The first coupling member 12 and second coupling member 14 are mutually connected through the intermediate member 16, the first coupling member 12 and second coupling member 14 are interfit into interfit sections 28 and 30 of the intermediate member 16 which cross at right angles mutually and extend, and the first coupling member 12, second coupling member 14, and intermediate member 16 include interfit indicating sections, respectively, and a relatively positional relationship between the first coupling member 12 and second coupling member 14 around an axis of rotation is fixed uniformly. |
