EFFECTS OF THE INVENTION The door contact device for the assembling part of the double door type door according to the present invention has the following remarkable effects.

According to the first aspect of the present invention, the leg piece of the door stopper is brought into contact with the rear surface of the face plate from the rear of one door body and pushed outward toward the end face plate side, thereby engaging with the attachment piece. As the joint piece slides into the end edge of the folding plate while intruding, the two leg pieces are elastically pressure-contacted, and the claws of the engaging piece prevent the end edge of the folding plate from engaging with the door, so that the door is fitted to the door. Since the hitting device is attached, the installation work is extremely easy.The door hitting device can be cut appropriately according to the size of the door body and can be placed along the entire length of the assembling part of the door body. It is excellent and can completely hide the gap between the left and right door bodies when closed. Also, in the mounted state, the elastic restoring force of the two leg pieces made of hard synthetic resin always acts in the direction of pressing the engagement piece to the edge of the folding plate, so that even if a shock is applied to the stop piece when it is closed, There is no danger that the hitting tool will come off the door body, and the mounting piece is in contact with the inner surface of the folding plate, so it is strong. Furthermore, the stopper, which is integrated with the mounting piece, bypasses the back surface of the rear plate of the one door and protrudes from the end face plate, and the buffer portion made of a soft synthetic resin is integrally formed at the tip of the stopper, Since the back plate of the other door is stopped when the door is closed, almost no impact noise is generated when the door is closed.

According to the second aspect of the present invention, by confirming that the ridge is positioned outside the end face plate of the door body, the claw of the engaging piece engages with the end edge of the folding plate in a retaining engagement. It is possible to confirm whether or not the door stopper is attached to the door body, and it is possible to prevent deformation such as twisting or bending of the stopper due to the presence of the protrusion.

According to the third aspect of the present invention, the end face plate of one door body may contact the end face plate of the other door body when the door is opened and closed even if the interval between the left and right door bodies is set narrow. Since there is no such gap, the clearance between the dining portions can be set as narrow as possible, dust and dirt can be prevented from entering the inside of the cabinet, and the appearance can be improved.
