PROBLEM TO BE SOLVED: To provide a connection structure of a push button capable of simply fitting a pantograph even in a small space, and to provide an in-vehicle audio device using the structure. SOLUTION: In this connection structure of a push button, an operation supporting point 25A of a pantograph 25 is locked to an operation panel 13, and a movable point 25B of the pantograph 25 is locked to the push button 15 by rotating around the operation supporting point 25A, whereby the push button 15 is connected to the operation panel 13; and a lock groove 31B opened nearly rearward with respect to the rotation direction of the pantograph 25 is formed on a lock part 31A of the operation supporting point 25A of the pantograph 25.
