Abstract

The present invention relates to a device for generating phase difference between two rotary elements by using a helical spline. A first rotary element connected to a central shaft in which a linear spline is installed and identically rotated and the helical spline in which a linear spline groove is formed inside a second rotary element and an inclined spline is formed to the outside are installed on the central shaft. The second rotary element generates the phase difference relative to the first rotary element by moving it in a central shaft direction.
