PROBLEM TO BE SOLVED: To provide a rotary encoder in which a code disk can be easily replaced. SOLUTION: A flange part 4a to which the ring-like rotating code disk 5 is fixed by screws is formed in a rotating disk 4. A protrusion part 4b is formed inside the flange part 4a in such a way as to protrude. The outer diameters of a magnet 10 and a magnetic body 12 to be secured onto a securing surface 42 of the protrusion part 4b are set smaller than the outer diameter of the protrusion part 4b. It is therefore possible to easily replace the rotating code disk 5 by removing screws 14 while the magnets 10 and 11 and the magnetic body 12 are secured to the rotating disk 4.
