In the turntable 1, the shaft member 4 has the square tube portion 12 fitted into the mounting hole 5 of the mounting object 2, and the shaft member 4 and the mounting object 2 are fixed.
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 8 a of the hole bottom 11 a of the concave portion 11 in the base plate 3, the base plate 3 is It is freely rotatable in the opposite direction. At that time, the mounting object 2 of the base plate 3
The plurality of rotating rollers 7 on the side facing the shaft are arranged at equal intervals on the shaft hole 8, that is, on the outer circular rib 9 b formed concentrically with the shaft member 4 as the center, and
Since the rotating shaft 7a is directed in the direction of the radial ribs 9c which are formed crosswise at equal angles to the a and 9b, the base plate 3 has the shaft member 4 as the center of rotation and the rotating roller 7 Can be freely rotated while rolling. Therefore, the base plate 3 is particularly suitable for an object (for example, a household appliance such as a television) which changes its orientation so that it can be easily used with one hand when placed on a normal table, or which cannot be held by a hand. It can be said that it is effective.

[0019]

As described above, according to the present invention, when the base plate is mounted on the object to be mounted via the shaft member, the base member can be fixed only by inserting the shaft member into the mounting object from the base plate side. It can be seen that the mounting operation can be simplified as compared with the related art, since the mounting can be performed in a state that can be rotated in both directions.
