A shock absorbing structure of the knob for car-audio is provided to minimize injury of a passenger and a driver by caving in a settling portion connected to the PCB substrate by the medium of the support rib and absorbing the impact force. A shock absorbing structure of the knob for car-audio comprises a base(40) consisting of the sheet form; a first elastic member(60) installed at the surface of the base; a PCB substrate(10) installed at the surface of the first elastic member; a second elastic member(70) installed at the surface of the PCB substrate; an audio panel(20) installed at the surface of the second elastic member; a settling portion(50) which is prepared in the PCB substrate and in which the boundary surface the support rib(51) is formed; and an insertion hole(21) formed in the audio panel is included so that knob be inserted
