。 A first clutch 8 is installed in the guide rail 1, which is slidably slidable in the front and back directions, and is biased rearward by a tensioned tension spring 9, on a guide rail 1 that includes a slider 4 that can be interlocked with the opening/closing operation of the door. A through hole 8 of the first clutch is provided with a deep groove 11a and a shallow groove 11b in series in the longitudinal direction so that the clutch can slide in the longitudinal direction by a predetermined stroke.
A stopper ball 10 is loosely fitted into the first clutch and the guide rail, and the stopper ball is installed between the first clutch and the guide rail so that the stopper ball can be engaged with and disengaged from the stopper hole 1b formed in the guide rail by means of the two concave grooves. The second clutch 11 is rotatably supported by the second clutch, and is capable of being engaged with and disengaged from the slider at a position where the second clutch and the second clutch have moved forward by a predetermined stroke with respect to the first clutch. A third clutch 12 is biased in the disengaged direction by a compression spring 14, and the first clutch 12, second and third clutches are
A door closing force auxiliary device for a door closer, characterized in that both clutches move relative to each other by a predetermined stroke, and an auxiliary door closing force is stored in a tension spring.
