Abstract

PURPOSE:To obtain a mechanism giving proper propulsive force by a method wherein the first shaft provided with a cylindrical case with a female screw being given torque by a spiral sping and free rotatable through a bearing is fitted with thread to the second shaft capable of reciprocating the provided with a male screw. CONSTITUTION:When a spiral spring 9 is wound up with a knob 11, the first shaft 4 rotates winding up a spiral spring 9. Through said rotation, the first shaft propells in the direction either a or b of the second shaft through the screws 5a, 7b. This depends upon whether it is a left-handed screw or a right-handed screw. When the winding up by said knob 11 is relieved, the first shaft 4 rotates in the inversed direction to the forced direction, thereby the second shaft propells in the opposite direction to said direction.
