Abstract: A net post suitable for use in ball games is comprised of a hollow cylindrical support, a cylindrical slider disposed telescopically in the support so that it can move upwards and downwards, a handle axle disposed rotatably in the support, and a handle removably connected to the end of the handle axle. A transmission mechanism is provided for transmitting a rotational force in accordance with the rotation of the handle axle to a control rod which is positioned perpendicularly to the handle axle to drive the slider upwards or downwards. A guide wheel is rotatably mounted at the top end of the slider, and a hook, which is provided on the support, serves for fixing the end of a rope on which a net is hung with the rope tightened over the guide wheel.
