Abstract
An induction detecting type rotary encoder includes: a stator; a rotor configured to be rotated with respect to a rotary shaft; a first transmitting coil; a second transmitting coil; a first receiving coil; a second receiving coil; a first magnetic flux coupling body; and a second magnetic flux coupling body. The first transmitting coil is disposed between the first and second receiving coils. A distance between the second transmitting coil and the rotary shaft is larger than that of the second receiving coil and the rotary shaft. The first magnetic flux coupling body forms a first track for causing a periodic change for each rotation. The second magnetic flux coupling body forms a second track for causing a periodic change for each rotation. The second magnetic flux coupling body has a pattern of which an inner peripheral side is substantially continuous in a circumferential direction.
