転の重さ調節装置。 In a track ball that has a ball that is rotatably supported by three contact points between each rotating shaft and a support roller provided in directions perpendicular to each other, the support roller is rotatably supported around a certain point as a rotation center. A cover having a first screw means for finely adjusting rotation and a circular opening through which a portion of the ball protrudes is fixed to the track ball body so that the position of the circular opening can be finely adjusted. and a second screw means for screwing the first
and a ball rotation in a track ball, characterized in that the gap between the ball and the circular opening is adjusted by adjusting the second screw means, thereby making it possible to adjust the weight of the ball rotation. weight adjustment device.
