Description of the Related Art Conventionally, as a swing door opening / closing device for closing a vehicle opening by a swing door which is moved up immediately before closing, as seen in JP-A-57-140485, a piston in a direct-acting air cylinder is used. A vertical screw shaft that moves up and down in the vertical direction in conjunction with the reciprocating motion of the door is provided, and the screw shaft is screw-engaged from the outer circumference, and the door is mounted on the cylindrical support rotatably and vertically movably through the arm. A ball screw mechanism consisting of a screw groove and a ball is adopted in order to operate smoothly in the motion conversion mechanism of such an opening / closing device, however, this ball screw mechanism has a very large number of parts. However, since it requires high processing accuracy, it is expensive, and since the mechanism is complicated, maintenance workability is poor.

開発された。Therefore, what should be eliminated from the opening / closing device is that the inner wall c of the opening b of the vehicle a as shown in FIGS.
In addition, a vertical vehicle pivot axis d is vertically movable in the axial direction and is rotatably supported and disposed, and a vertical door pivot axis g is rotatably disposed on the inner wall f of the swing door e. Set up
The vehicle pivot axis d and the door pivot axis g are coupled by a coupling arm h, while the drive arm m is attached to the rotary drive axis k of the drive source j provided at a position lower than the coupling arm h in the vehicle a. An opening / closing device has been developed in which the connecting rod p, which connects the drive arm m and the connecting arm h and is arranged in an inclined shape, is connected via a universal joint q to simplify the upward movement mechanism.

た。However, in this opening / closing device, the swing door e is moved upward via the connecting arm h while the inclination angle of the connecting rod p arranged in an inclined shape is increased, so that the initial stage of such upward movement. Since the operating force is large with respect to the final operating force, there is a drawback that a smooth closing operation cannot be performed. Further, as the tilting angle of the connecting rod p at the time of closing approaches a vertical direction, the swing door e becomes free even if the drive source j becomes free. In order to increase the upward stroke of the swing door e, it is necessary for the drive arm m and the connecting rod p to have a length longer than that, and the upward movement mechanism itself becomes large. Therefore, the drive arm m further projects into the opening b to reduce the space for getting on and off the vehicle, which may be an obstacle.
In addition, the shape of the protective cover for safety is complicated, and there is a drawback in mounting due to the space of the opening b.

First, in order to close the swing door 3 from the open state, the drive source 26 is operated and the rotary drive shaft 26a is closed. When it is rotated to, the connecting rotary shaft 9 that is connected to the rotary drive shaft 26a also rotates, whereby it is attached to the tip end side of the arm portion 12 of the connecting rotary shaft 9 and the upper end surface of the cam concave portion 22 of the cam member 19. The roller 14 in contact with 22a rotates in a horizontal plane and tries to roll from the upper position to the lower position of the upper end surface 22a, but at this time, the component force that pushes up the cam member 19 by the roller 14 causes the swing door 3 to move. It is set to be smaller than the total force of its own weight and the elastic force of the spring 17, and the movement of the swing door 3 in the closing direction is not restricted. As it is Rotational force of Dogen 26 is transmitted directly to the vehicle pivot 15 via the cam member 19 swing door 3 is moved in the closing direction.

Is transmitted to the roller 14 which is in contact with the high position of
14, the force that pushes the upper end surface 22a in the horizontal rotation direction to rotate the cam member 19 in the same direction changes to the component force that pushes up the cam member 19 and is larger than the total force of the weight of the swing door 3 and the elastic force of the spring 17. Apparently when it is formed, the roller 14 rolls from the high position of the upper end surface 22a to the low position, and the cam member 19 moves upward, whereby the vehicle pivot 15 connected to the cam member 19 is moved. Move up.

その実用的効果甚だ大なるものである。In addition, the roller 14 is provided on the upper end surface of the cam recess 22.
Since it is connected to 22a for rolling, rattling due to uneven power on the switchgear with the conventional inclined connecting rod p is eliminated, smooth closing operation is possible, and the drive source 26 is freed. However, the conventional connecting rod p that should regulate the downward movement of the swing door 3
Since it can be moved down easily because it does not have any, and because it is moved up by the cam mechanism, it is possible to set an arbitrary upstroke stroke by selecting the height difference of the upper end surface 22a of the cam member 19, the trajectory, etc. Even if the upward movement stroke is lengthened, there is no protruding portion into the opening of the vehicle 2, so that a cleaner form can be achieved and the space inside the opening is not reduced, so that it does not interfere with the lifting and the safety cover. The shape is simple and the installation is easy, and its practical effect is enormous.
