Door operator
First Claim
1. A door operator adapted to open and close a side door supported on a side of a vehicle body through a hinge, the door operator comprising:
- 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 includinga driving arm extending radially from the output shaft of the drive unit, anda driven arm includinga first end turnably connected to the vehicle body, anda second end separately formed from the first end and turnably connected to the driving arm through a rotation shaft, whereinthe driven arm is configured to rotate about the rotation shaft with respect to the driving arm,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, andthe driven arm and the driving arm are connected to each other while allowing for a change in distance from a shaft core of the rotation shaft to a shaft core of the output shaft.

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.
