The purpose of the present invention is to provide a fixing device for the metal wheel of a top, wherein the fixing device is to improve the fastening structure of the metal wheel in order to sufficiently vibrate the metal wheel when the top collides. According to the present invention for the above effect, the fixing device for the metal wheel of the top comprises: the metal wheel of which the center has a punched through-hole having at least one fastening part on the inner circumference thereof; a rotation part installed at the lower side of the metal wheel, and supporting the metal wheel to be rotated; and a fixing part coupled to the rotation part by penetrating the metal wheel, and the supporting the metal wheel to be fixed to the rotation part, wherein the fixing part includes: a fixing part body having a flange on the upper side thereof; a coupling groove formed on the bottom surface of the fixing part body, and coupled to the rotation part when inserted with the part of the rotation part; a wedge-shaped holding protrusion protruding from the lower side of the fixing part body, and supporting the metal wheel to be positioned on the fixing part body; a fixing part fastening protrusion radially protruding from the outer circumference of the fixing part body, having a certain length, and engaged with the fastening part of the metal wheel; and a protrusion installed on the holding protrusion, and forming a distance between the metal wheel and the fixing part. According to the present invention, the fastening structure of the metal wheel of the top is improved to sufficiently vibrate the metal wheel when the top collides, thereby maintaining a collision sound generated when the top collides. In addition, according to the present invention, a sufficient space is formed to vibrate the top, thereby making the collision sound clear. |
