PROBLEM TO BE SOLVED: To provide a joystick capable of accurately detecting tilting of an operation shaft without using a gear mechanism with a compact and simple structure.SOLUTION: An operation shaft 15 is supported spherically around one point by a spherical bearing mechanism provided on an upper case 3 and subjected to a tilting operation by an operator. The tilting operation by the operation shaft 15 is converted into a travel in one plane by a shaft guide 46. A Y-axis slide 50 and an X-axis slide 55 convert the plain motion into orthogonal two axial directions, respectively. Two links, an X-axis link and a Y-axis link, extend the travel by a lever. The extended travel is detected by two travel detection slides. |
