PROBLEM TO BE SOLVED: To provide an electronic device capable of reducing the number of components used for preventing erroneous operation. SOLUTION: The electronic device 1 has a rotary knob 5, and the rotary knob 5 is supported by a rotary axis 53. A switch 7 is pushed by the rotary knob 5 by the rotation thereof. Erroneous operation is not generated even if an external force in a direction of pushing the rotary knob 5 is added. Further, a difference of level between the outer face of a front panel 3 as an external member and an operation face 51 of the rotary knob 5 may be formed. For example, the electronic device 1 is a navigation device, or a steering wheel device. COPYRIGHT: (C)2006,JPO&NCIPI
