A top launching device for launching a top includes a device body and an operating belt. The device body includes first and second input rotors to rotate, an output rotor configured to hold the top in a state with a central axis of the output rotor aligned with a central axis of the top and configured to rotate and impart the rotational force to the top, and a coupling rotor configured to transmit the rotational force from the input rotor to the output rotor. The operating belt is configured to be inserted in the device body, and to be engaged with either the first or the second input rotor. The output rotor is configured to rotate the top, impart the rotational force to the top, and release the top. The operating belt is configured to be selectively engaged with one of the first and second input rotors.

A toy top includes a shaft portion, an additional part and an engaging part. The shaft portion includes a spinning shaft. The additional part is attached to the shaft portion movably in an axis direction of the spinning shaft. The engaging part engages the additional part with the shaft portion at different positions in the axis direction of the spinning shaft. An attachment position of the additional part is changeable by changing engagement of the additional part by the engaging part. A grounding state or a height of the shaft portion is changeable according to change of the attachment position of the additional part.
