摘要： 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.

摘要： A waterproof structure of a door latch device, in which one end part of a cable is connected to an input lever including one end part projecting toward outside of a case, includes a cover including: a cover main body having a box shape with a cover opening, the cover main body being configured to house the one end part of the input lever and the one end part of the cable via the cover opening when the cover main body abuts on the case; and a cover supporting body extending from the cover main body. The cover is attached to the case via the cover supporting body in a state in which the cover main body is movable between a closed position at which the cover main body abuts on the case and an opened position at which the cover main body is separated from the case.
