Abstract
A roller arm unit of the present invention has three or more pulleys by odd pieces. A door-opening cable and a door-closing cable extending from a power unit have tip ends fixed to a first and second end portions of a guide rail by way of the pulleys. The door-opening cable and the door-closing cable are intersected with each other between two neighboring pulleys. A path length of a take-up side cable becomes short and a path length of a pay-out side cable becomes long when the roller arm unit is caused to be swung due to influence of the curved portion.
