[0005]

[Means for Solving the Problems]

 The mounting body, the rod provided on the upper surface of the mounting body, the pin provided on the tip of the rod, the rod insertion groove that supports the door roller and is opened on the lower surface, the long hole that is opened in this rod insertion groove, and the long hole is the lower surface. The body is provided with a notch that is narrower than the diameter of the rod that opens, and a spring that is provided in the rod insertion groove.The notch is expanded and deformed by a pin and inserted into the rod insertion groove of the rod body. Connected.

[0006]

[Work]

 By inserting a spring into the rod insertion groove of the main body and expanding and deforming the notch with a pin to face the elongated hole, the rod can be inserted into the rod insertion hole of the main body and assembled.

[0007]

【Example】

 As shown in FIG. 2 to FIG. 5, the retaining body 1, the rod 2, the main body 3, the spring 4, and the door roller 5 constitute a retaining device, and the retaining body 1 has a rectangular parallelepiped shape and is formed on one side face 1a and both end faces 1b, 1b. It has an open notch recess 6, a screw hole 7 is formed over the bottom face 6a of the notch recess 6 and the other side face 1c, and a screw 8 is screwed into the screw hole 7, and the upper face of the mounting body 1 is formed. A rod 2 is provided on 1d, and a pin 9 is inserted and attached to the tip of the rod 2 so that both ends of the pin 9 project from the outer peripheral surface of the rod 2. The main body 3 includes a lower main body 10 and an upper main body 11. The lower main body 10 is formed with a rod insertion groove 12 that is open to the lower surface 10a, and opposite side surfaces 10b and 10b are opened to the rod insertion groove 12. Each of the long holes 13 is formed, and the lower edge portion 13a of each of the long holes 13 is opened at the lower surface 10a of the main body 10 by the notch 14 having a width narrower than the diameter of the pin 9, and the vertical slit 15 is formed in the upper main body 11. A door roller 5 is rotatably supported by a support shaft 16 below the vertical slit 15. Because of this, the spring 4 is inserted into the rod insertion groove 12 of the lower body 10, and the rod 2 is inserted into the rod insertion groove 12 so that the notch 14 is expanded by the pin 9 so as to face the elongated hole 13. It can be assembled. Then, as shown in FIGS. 6 and 7, the mounting body 1 and the main body 3 are inserted into the outward recess 21 of the screen vertical frame 20 which constitutes the screen A, and the screw 8 forms the connecting plate 2 2 which constitutes the outward recess 21. And press one side surface 1a of the mounting body 1 against the protruding portions 23a, 24a of the vertical side plates 23, 24 of the screen vertical frame 20 to mount the mounting body 1a on the screen vertical frame 20 and mount the screen A on the upper body 11. The vertical slit 15 is inserted into the screen door rail of the screen frame and attached to the screen frame. Numeral 26 is a screen frame. As a result, the spring 4 pushes the main body 3 upward and urges it to bring the door roller 5 into contact with the lower end surface of the screen door rail 25 so that the screen door can run smoothly, and when the screen door A tries to float upward, the spring 4 It can be prevented from rising due to the urging force of.

[0008]

[Effect of the Invention] Since the main body 3 is urged upward by the spring 4 with respect to the mounting body 1 by using the rod 2 as a guide, the main body 3 is mounted by mounting the mounting body 1 on the screen vertical frame 20 forming the screen door A. Since the door roller 5 supported on the screen door can be pressed against the screen door rail of the screen frame, the screen door A can be smoothly driven, and the lift of the screen door A can be restricted to prevent the screen door A from coming off. The spring 4 is inserted into the rod insertion groove 12 of the main body 3, and the rod 2 is inserted into the rod insertion groove 12 while the notch 14 is expanded and deformed by the pin 9 to connect the attachment body 3 and the rod 2. Since it can be assembled, its assembling work is simplified.
