Abstract
This face gear has a plurality of annularly arranged gear teeth. A recess for holding grease or another lubricant is formed in the tooth surface of each gear tooth. A recess forming area, which is the area in which the recess is formed, is provided between the tooth bottom and the pitch point in each gear tooth. In other words, a recess is not formed in the part of the tooth surface that is located between the tooth tip and the pitch point. As a result, the gear teeth can be effectively lubricated while minimizing instability in the meshing state between gears.
