Abstract
A wormis composed of an annular tooth bodyhaving a toothon the outer surface thereof, a core bodyinserted inside the annular tooth body; and an elastic coupler, which can be transformed in the radial direction, for coupling the core bodywith the annular tooth body. The wormis engaged with the worm wheel with the elastic couplerbeing transformed in the radial direction in such a manner that a negative amount of backlash is generated at the engagement portion. This can be also employed for the worm wheel. With a reduction gear combination having this structure, the backlash amount at the engagement portion can be adjusted to a proper amount without selecting elements such as the worm and the worm wheel to be assembled.
