Abstract: A door operator opens and closes a side door supported on a side of a vehicle body through a hinge, and includes: a drive unit arranged in an inner space of the side door; and a link mechanism configured to connect an output shaft of the drive unit and the vehicle body. The link mechanism includes a driving arm extending radially from the output shaft of the drive unit, and a driven arm turnably connected to the vehicle body. The link mechanism is configured to open and close the side door with respect to the vehicle body through the driving arm and the driven arm when the drive unit is driven, and the driven arm and the driving arm are connected to each other while allowing for a change in distance from a relative pivot core to a shaft core of the output shaft.
