Abstract
A joystick device includes a case so that first and second rocking members are respectively supported in a overlapped manner by first and second bearings formed in the case with their first and second elongate holes positioned perpendicular to each other. The operation of the lever inserted through the first and second elongate holes causes tilt movement in at least one of the rocking members so that the movement of the rocking member is supplied as a pulse signal by a detecting device. The lever includes an engaging portion engaged with the rocking member on the upper side, and a spherical portion formed at a position above the same rocking member. The cover has a hole having an inner peripheral edge with which contacted is an outer peripheral surface of the spherical portion so that the lever is supported operable in every direction. A spring is provided with the case, which acts to press down the rocking member thereby returning the lever to a neutral position.
