PROBLEM TO BE SOLVED: To provide a motor with an optical encoder, which achieves a simple configuration and easy assembly.SOLUTION: A motor with an optical encoder includes: a motor 101 having a shaft 102; an encoder disk 112 attached to the shaft 102; and a photointerrupter 200 having such structure that the encoder disk 112 is sandwiched between a light emission part 201 and a light reception part 202 in a noncontact manner. A mounting hole 132 through which the shaft 102 of the encoder disk 112 passes has a long-hole shape of extending away from a shaft center. |
