The rotating body A configured as described above is provided as a top for a child. When the rotating shaft 10 is pinched and rotated, the positive contacts 6 and 8 are closed by centrifugal force, and the vibration motor 3 is driven. When the rotating body A is seated on the support base 12, the rotating body A continues to rotate on the support base 12 due to the rotational vibration bias caused by the vibration motor 3.

Next, the second embodiment will be described. As shown in FIGS. 3A, 3B, and 3C, the frame main body 2 in which the single rotation support shaft 1 is integrally suspended at the center portion. Is provided with two button batteries (1, 5V) 15 as a power source on the upper surface of the base 14, a coin-shaped vibration motor 3 is provided on the lower surface, and, as shown in FIG. Five LEDs 16 that emit light of each color are provided between the batteries 15 in the radial direction. Further, the power source of the button battery 15 is electrically connected to the vibration motor 3, but the switch mechanism 5 that connects the vibration motor 3 to the power source has the + side terminal of the vibration motor 3 penetrating the insulating base 14. Is projected as a positive contact 6 on the outer peripheral end side, the negative terminal of the vibration motor 3 is connected to the negative side of the button battery 15, and one end of a coil spring 17 corresponding to a lead wire is connected to the positive terminal of the button battery 15. At the same time, a positive contact 8 which is provided at the other end of the coil spring 17 and is made of a weight swinging outward by centrifugal force is arranged to face the positive contact 6 with a slight gap. Further, in the electric circuit of the switch mechanism 5, a light emission control unit 18 accompanied with an IC chip for controlling the LED 16 of each color with various lighting patterns simultaneously with energization to the vibration motor 3 is disposed.
Then, a cap 11 having a shaft 10 integrally installed is joined to the opening 9 at the top of the top body 2 by an interference fit.

The rotating body B configured as described above is provided as a top for a child, and when the rotation shaft 10 is pinched and rotated, the positive contacts 6 and 8 are closed by centrifugal force and the vibration motor 3 is driven. The LED 16 of each color, which is controlled in various lighting patterns by the light emission control unit 18, emits light, making the frame play more fun with a beautiful light emission color.
In the rotating body B, as described above, when the rotating support shaft 1 is inserted into the through hole 13 of the support base 12 shown in FIG. 2 and the rotary body B is seated on the support base 12, The rotating body B continues to rotate on the support base 12 due to the bias of rotational vibration by the vibration motor 3.
