PROBLEM TO BE SOLVED: To obtain an opening/closing device prevented from chattering phenomenon when opening/closing a contact, miniaturized by reducing the load burdened to an operation axis and operation mechanism. SOLUTION: The opening/closing device 100 has fixed contact members 104, 105, 106 and moving contact members 107, 108, 109. The moving contact members 107, 108, 109 are jointed to an operation axis 110 jointed to an operation mechanism 111, and made to rotate around pins 112, 113, 114 respectively according to the reciprocal movement of the operation axis 110. The slope of the moving contact members 108 is made more steep than that of the moving contact member 109, and more gentle than that of the moving contact member 107. By the above, the distance between the moving contact members 108, 109 and the contact members 105, 106 are made long when the moving contact member 107 contacts with the fixed contact member 104, and the chattering between the moving contact members 108, 109 and the fixed contact members 105, 106 is prevented.
