ABSTRACT:
A joystick controller sufficiently strong and durable not to easily be broken even when handled somehow roughly, reasonably compact and which can be manufactured with less costs, is provided by composing it of a housing provided thereon with a plurality of potentiometers, a hollow shell bearing born inside the housing rotatably in one direction and which has a first pair of auxiliary arms attached on either side thereof and extending outwardly; an intermediate bearing born inside the shell bearing rotatably in a direction orthogonal to the shell bearing; a joystick attached rockably on the intermediate bearing and extending upwardly of the housing through a first pair of guide slots formed in the shell bearing; a core bearing pivoted inside the intermediate bearing rotatably in a same direction as the intermediate bearing; and a second pair of auxiliary arms attached on the core bearing, extending in a direction orthogonal to the first pair of auxiliary arms through an aperture formed in the intermediate bearing and a second guide slot formed in a direction orthogonal to the first pair of guide slots in the shell bearing and rockably born inside the housing; and coupling the first and second pairs of auxiliary arms to rotating shafts of the potentiometers respectively.
