摘要：
A reduction gear in which an engaging surface of gear teeth is processed so that grease for lubricating the engaging surface is sufficiently supplied over the entire of the engaging surface, thereby reducing the friction caused on the engaging surface, and increasing the durability of the gear teeth is provided.
In a reduction gear which includes a worm made of metal and a worm wheel having gear teeth which engage with the worm, wherein at least the gear teeth of the worm wheel are made of synthetic resin, and in which an engaging surface of the gear teeth is lubricated by grease, the engaging surface has over an entire surface a plurality of grease reservoir grooves formed along a sliding line of the engaging surface.
