Engage. On the other hand, the head 14 of the shaft member 4 contacts the peripheral surface 8a of the shaft hole 8 of the base plate 3 to complete the assembly.

Next, the screw 16 is screwed in from the insertion hole 17 in the head portion 14 of the shaft member 4 to reach the inside of the tubular member 19 inserted into the square tubular portion 12. At this time, since the screw 16 moves the tubular member 19 inside the rectangular tubular portion 12 in a pulling-up direction as the screw 16 rotates, the movement of the tubular member 19 causes the top end of the elastic locking piece 15 to move. Face 15
It is possible to bring a into close contact with the hole edge portion 20 of the mounting hole 5 and fix it without rattling.

After assembling the base plate 3 into the mounting hole 5 of the mounting object 2, the cylindrical portion 18a of the cap 18 is mounted.
Is fitted into the recess 11 of the base plate 3 and the recess 18
1 is closed, and the upper surface of the base plate 3 is flattened to achieve the attachment.

In the rotary table 1, the shaft member 4 has the square tube portion 12 fitted into the mounting hole 5 of the mounting object 2 so that the shaft member 4 and the mounting object 2 are in a fixed state.
Since the main body shaft portion 13 is located in the shaft hole 8 and the head portion 14 is in contact with the peripheral surface 8a of the hole bottom 11a of the recess 11 in the base plate 3, the base plate 3 is not directly attached to the shaft member 4. It is rotatable in the opposite direction. At that time, the object 2 to be attached to the base plate 3
The plurality of rotary rollers 7 on the side facing each other are arranged on the shaft hole 8, that is, on the outer circular rib 9b formed concentrically around the shaft member 4, at regular intervals, and at the same time.
Since the rotary shaft 7a is formed in the radial ribs 9c formed by crossing a and 9b at equal angles, the base plate 3 is rotated about the shaft member 4 and the rotary roller 7 is mounted on the object 2 to be mounted. You can freely rotate while rolling. Therefore, the base plate 3 is particularly suitable for an article whose weight cannot be easily changed with one hand when placed on a normal table and which cannot be held by hand (for example, a household electric appliance such as a television). It can be said that it is effective.

[0019]

As described above, according to the present invention, when the base plate is attached to the object to be attached via the shaft member, the base member is simply inserted by inserting the shaft member from the side of the base plate into the object to be attached. It can be seen that the mounting work can be simplified as compared with the conventional one, because it can be assembled on both sides in a rotatable state.
