Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.
In the first embodiment for carrying out the present invention shown in FIGS. 1 to 10, reference numeral 1 denotes a floor joint device for closing the joint portion 2 between the left and right floor frames 3, 3 provided via the joint portion 2. The floor joint device 1 includes a plurality of support bars 4 attached to the left and right floor frames 3 and 3, a support plate 5 attached to the upper surface of the plurality of support bars 4, and the support plate 5. The supported joint plate 6, the cover plate 8 provided above the support plate 5 with a space 7 in which the joint plate 6 slides, and the space 7 in which the joint plate 6 slides are installed. The bearing roller 9 is configured to support the load applied to the plate 8.

  The support bar 4 includes a plurality of cylindrical support arms 10 each having a rear end portion 10a attached to one floor frame 3 and having a roller 11 on the upper inner wall of the front end portion 10b. A front end portion 13a having a roller 12 at the bottom is inserted, and is composed of a plurality of insertion support arms 13 having a rear end portion 13b attached to a floor case 3 opposite to the floor case 3 to which the support arm is attached. Yes.

  The support arm 10 is a square cylindrical support arm main body 14, a mounting portion 15 formed so as to protrude outward at the upper rear end of the support arm main body 14, and is fixed to the mounting portion 15. An angle-shaped bracket 17 pivotally supported by a pivot pin 16 and a roller 11 attached to the upper inner wall of the distal end portion of the support arm main body 14 are configured. A bar-shaped slide member 19 having a lower roller 18 is fixed to the bracket 17 at the tip of the support arm 10, and slides in the front-rear direction on a slide rail 20 provided on the outer wall of one floor frame 3. It is installed as possible.

  The insertion support arm 13 includes a plate-like or cylindrical insertion support arm main body 21 that is slidably inserted into the plurality of cylindrical support arms 10, and a lower end of the insertion support arm main body 21.
