  • Patent number: 5823057
    Abstract: A joy stick structure for video game comprises a pressing plate having a central socket integrally provided thereunder, a body having a central through hole, a plurality of first spaces and a second space, a stick having a first end with a sphere thereof and a second end firmly received within the central socket of the pressing plate through the central through hole of the body and a plurality of transmission mechanisms securely received within the first spaces of the body. A positioning boss is formed integrally on the sphere and received within the second space of the body preventing unrequired movement of the stick. The sphere of the stick provides a smooth sliding effect.
