Abstract
A positioning structure for a worm wheel which is configured to mesh with a worm spindle and contains: a body, a plurality of rolling assemblies, and at least one attaching material. The body includes plural accommodating grooves and plural recesses, wherein each recess forms on a bottom face of each accommodating groove and communicating with said each accommodating groove. Each rolling assembly includes a holder, a rolling ball, and a magnetic attracting element, wherein a width of the holder is less than a width of said each accommodating groove so as to form a gap between the holder and said each accommodating groove. Each attaching material is filled in the gap, and said each rolling assembly is adjustably moved to a fixing position of said each accommodating groove by using said each recess, such that said each attaching material locates the holder in said each accommodating groove.
