ABSTRACT:
A worm1is composed of an annular tooth body11having a tooth10on the outer surface thereof, a core body12inserted inside the annular tooth body11; and an elastic coupler13, which can be transformed in the radial direction, for coupling the core body12with the annular tooth body11. The worm1is engaged with the worm wheel with the elastic coupler13being 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.
