Claim Text:
1. A vibration preventing device for a vibration preventing type lighting fixture, which is installed between a socket coupling part of the lighting fixture and a lamp socket coupled to the socket coupling part to protect a lamp from an external vibration or shock, characterized in that at least one of buffering protrusions are formed to protrude on an outer surface, an upper surface and a lower surface of a body formed of shock-buffering material, the body is inserted into and coupled with the socket coupling part of the lighting fixture in the state in which the body and the socket are in point-contact with each other by the buffering protrusions formed on the outer surface, the upper surface and the lower surface, the body has a narrow upper portion and a wide lower portion by gradually increasing the entire width of the body from the upper portion toward the lower portion so that the lower portion is forcibly inserted in the socket coupling part of the lighting fixture, rather than the upper portion, to allow the body to be coupled to the socket coupling part.
