[object] To improve the noise resistance of an electronic device by an inexpensive and simple configuration. [Solving means] An electric retractor (1) comprises a winding part (10) configured to extract and wind a seatbelt (102) that restrains an occupant, an electric driving part (30) for extracting or winding the seatbelt (102) by a driving of a motor (20), and a control part (50) configured to control the driving of the motor (20), wherein respective external covers (12, 22, 34, 52) of each of the parts (10, 20, 30, 50) are electrically connected to the same potential, and at least one of the external covers (12, 22, 34, 52) is connected to a GND. |
