Abstract
A manual control device composed of: a housing; a joystick; and a joint supporting the joystick in the housing to enable the joystick to pivot about two mutually orthogonal axes relative to the housing. The joint is an elastic molded plastic part composed of an interior portion secured to the joystick, a peripheral portion secured to the housing and a connecting portion extending between, and connecting, the interior portion and the peripheral portion. The interior portion has the form of a first cylinder and the peripheral portion has the form of a second cylinder, the first and second cylinders being concentric with one another when the joystick is in a neutral position. The connecting portion has a frustoconical shape when the joystick is in the neutral position and is stressed when the joystick is pivoted away from the neutral position.
