A chassis front of an audio of a vehicle is provided to insulate external noise efficiently by collecting noise such as static electricity in a protruded part with plural saw teeth around a lower part of a cassette tape inlet before putting a cassette tape into the audio. A chassis front(100) of an audio of a vehicle is composed of a cassette tape inlet(130) for inserting or withdrawing a cassette tape, and a protruded part(135) is formed around a lower part of the cassette tape inlet. Plural saw teeth(131) are formed in the protruded part in the lower circumference of the cassette tape inlet. A horizontal sill is protruded forward and extended horizontally in the lower circumference of the cassette tape inlet. A vertical sill is formed upward in an end of the horizontal sill, and extended vertically. Plural bending parts are formed in the vertical sill to insulate noise by discharging noise through the vertical sill and the horizontal sill to the chassis front in putting the cassette tape into the audio.
