Abstract:
1. A manipulation mechanism comprising: a manipulation reference plane which is perpendicular to an axis of the manipulation mechanism; a first imaginary plane which includes the axis and which is perpendicular to the manipulation reference plane; a second imaginary plane which includes the axis and which is perpendicular to the manipulation reference plane and the first imaginary plane; a first oscillating portion which is configured to oscillate on the first imaginary plane; a first guide member which is disposed on the first imaginary plane and which regulates an oscillating locus of the first oscillating portion; a second oscillating portion which is configured to oscillate on the second imaginary plane; a second guide member which is disposed on the second imaginary plane and which regulates an oscillating locus of the second oscillating portion; and a manipulation stick which is fixed to the second oscillating portion and which is disposed so as to be capable of moving on the second imaginary plane, wherein: the first oscillating portion comprises: the second oscillating portion comprises:
