The present invention provides a toy comprising : a rotator (18) which is capable of exhibiting a gyro effect ; a driver (20) connected to the rotator (18) for rotating the rotator (18) to allow the rotator (18) to exhibit the gyro effect ; and a device (26, 28) capable of causing the toy falling down or tilting to show a spin or a rotation in the same direction as a rotation of the rotator (18) so that a rotational axis of the rotator (18) rotates or swings to draw a cone-shaped locus thereof, thereby to reduce swing motion of the rotational axis or to narrow a spread of the cone-shaped locus, whereby the rotational axis of the rotator (18) is forced and moved onto a center and vertical axis, and the toy comes stand right-up and stabilized in a standing right-up position.
