DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decoration device for rotating a decoration while floating the decoration by a repulsive force of a magnet.

[0002]

2. Description of the Related Art For example, there has been known a decoration device for rotating a decoration body by driving force from a timepiece movement.
FIG. 5 shows an example of such a decoration device. In the decoration device shown in FIG. 5, the decoration body 51 is supported and fixed to the end of the decoration body support member 55, and the through hole 55a formed in the decoration body support member 55 is inserted into the rotation shaft 56 of the timepiece movement 57. The decorative body supporting member 55 is movable in the axial direction of the rotation shaft 56. The transmission of the driving force from the rotating shaft is performed, for example, by forming a key on the rotating shaft and forming a spline into which the key fits in a through hole of the support member.

In such a decoration device, the decoration body may not be able to be rotated due to a frictional force between the bottom surface of the decoration body support member 55 and the magnet holding member 54, a load applied to the rotating shaft, or the like. Therefore, for example, a ring-shaped magnet 52 is mounted on the decorative body support member 55, and the magnet 53 is mounted on the magnet holding member 54 at a position facing the magnet 52 so that a repulsive force is generated between the magnet 52 and the magnet 52. Then, the decorative body support member 55 and the decorative body 51 are floated with respect to the upper surface of the magnet holding member 54 by the repulsive force between the magnets 52 and 53, so that the frictional force at the time of rotation and the rotating shaft are reduced. Such a load is reduced to facilitate rotation of the decorative body.

[0004]

In the decorative device described above, the decorative body is placed vertically.
Depending on the product, there may be a case where the decoration is desired to be suspended in the vertical direction. In such a case, when the decoration device is suspended, that is, when the clock movement 57 is turned upside down, the load of the decoration body 51 is applied to the rotating shaft 56. In addition, if the decorative body support member 52 is not stopped in the axial direction, the decorative body 51 falls off from the rotating shaft 56. Therefore, when the decorative body 51 is used by hanging it in the vertical direction, it is necessary to newly manufacture a member for hanging, and there has been a problem that a product cost is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem. In a decoration device for rotating a decorative body while floating the decorative body by a repulsive force of a magnet, the decorative body is placed in a vertical direction. It is an object of the present invention to provide a decoration device that can operate in any of a state and a suspended state.
