[Problems to be solved by the device]

 However, in the sealing device of this conventional technology and the above-mentioned proposed technology, the airtight member is integrally incorporated in the main body frame. To mount this sealing device on the lower frame of the door, the sealing device is adjusted to the width of the door. However, the sealing device is composed of an airtight member mainly made of rubber and a different material for the main body frame made of aluminum, and the airtight member is built in a movable state inside the main body frame. Since it has been cut, it cannot be cut beautifully. In addition, since the sealing device cut to a predetermined size is mounted on the lower frame of the door and then the door is suspended on the door frame on the frame side, there is variation in the gap between the airtight member of the sealing device and the lower frame of the door. If the airtightness is poor and the airtightness is poor, or the opening and closing operation of the door is disturbed, it must be adjusted. Furthermore, during use, the airtight member needs to be replaced due to wear. However, since the sealing device has an airtight member integrally incorporated in the main body frame, the door incorporated in the door frame must be removed to adjust the sealing device or to perform replacement work, which is a troublesome door. Not only was it extremely heavy labor, but the work efficiency was poor. In view of the above-mentioned problems, the present invention has been made to solve the problem, and the airtight member of the seal device is removably incorporated into the frame member, so that adjustment or replacement work of the airtight member can be easily performed. The purpose of the present invention is to obtain a sealing device that can be securely and firmly attached to a door beautifully.

The airtight member 8 has a seal portion 9 and an actuating body 15. The seal portion 9 is fitted with a rubber-like elastic seal 11 so as to project from the lower surface of the movable frame 10, and auxiliary seals 12, 12 are provided on both side surfaces. A connecting piece 13 is erected on the upper surface of the central portion of the movable frame 10 and an arcuate hole 14 is formed in the connecting piece 13. The actuating body 15 is formed in a generally inverted convex shape in cross section in which a step portion 17, 17 is formed at the lower end of a gate shape having an end surface 16 on one side and an opening at the lower end, and a narrow guide portion 18 is provided. The actuating block 19 is movably fitted in the actuating body 15, the actuating block 19 and the base end of the rocking piece 20 are pivotally attached to each other by a pin 21, and the rocking piece 20 is mounted near the base end. The pin 22 is pivotally attached to the guide portion 18, and the tip of the swinging piece 20 is connected to the arc-shaped hole 14 formed in the connecting piece 13 by the pin 23. Further, the operating rod 24 is attached to the operating block 19 by penetrating the one end face 16 of the operating body 15, and the coil spring 26 is provided between the stop pin 25 projecting from the operating rod 24 and the side surface portion 16 of the operating body 15. Install bullets. Further, the sensing body 27 is adjustably screwed to the tip of the operating rod 24, and a compression spring 28 for holding the adjusted position of the sensing body 27 is elastically provided. Further, one end of the connecting body 29 is fixed to the actuating body 15, and a mounting piece 30 is bent upward at the other end, and the mounting piece 30 is mounted on the side surface portion 2 of the hinge-side vertical frame of the door 1. A hole 31 is formed.

With this structure, in order to assemble the seat device 5 into the door 1, first, the frame member 6 of the seat device 5 is fitted into the lower frame 4 and then fixed by the screw 32. To install. Then, the actuating body 15 of the airtight member 8 is inserted from the opening of the frame member 6 on the hinge side of the door 1, the step portion 17 of the actuating body 15 is placed on the guide rib 7 of the frame member 6, and the guide member The part 18 is fitted between the guide ribs 7, 7. Then, when the connecting body 29 is pushed in, the operating body 15 is guided by the guide portion 18 and slides in the frame member 6, and the mounting piece 30 of the connecting body 29 causes the side portion 2 of the hinge-side vertical frame 2 of the door 1. Then, the screw 33 is screwed in from the mounting hole 31 and the mounting piece 30 is mounted on the side surface portion 2 of the hinge-side vertical frame of the door 1. As a result, the actuating body 15 is assembled at a predetermined position in the frame member 6, and the sensing rod 27 attached to the actuating block 19 in the actuating body 15 and the sensing body 27 at the tip of the actuating rod 24 are located on the side surface portion 2 of the hinge-side frame of the door 1.
