PROBLEM TO BE SOLVED: To provide a push-button unit which has in itself a function to prevent button elements from moving together without adding an extra component. SOLUTION: The push-button unit includes an elongated rib 10 and a button element 20 connected with the rib 10 with a hinge portion 30 in-between. The long and thin rib includes a pressure receiving rib 50 as a pressure receiving body. The pressure receiving ribs 50 are lapping on each other inside a cabinet 40. When the button element 20 is pushed down to make a displacement movement, the pressure receiving ribs 50 lapping on each other inside the cabinet 40 prevent the long and thin rib 10 from being twisted and prevent another button element 20 from moving together.
