Abstract
A spinning arm that converts a rotational motion of a shaft to a linear movement of an object that includes a revolving piece and a rod. The lower end of the rod is connected to the shaft and the upper end is axially connected to the revolving piece in a state of tilting aside in relation to the rod so that the revolving axis line of the revolving piece crosses the rotation axis line of the rod. The revolving piece can move outwards and roll over the object when its tilt is from right to left. When the revolving piece rolls over the object in a first direction it exerts an upward force that moves the object upward, and when it rolls in a second direction it exerts a downward force that moves the object downward.
