摘要

A webbed spiral bevel gear formed by cold forging includes: gear teeth formed at a peripheral surface of the gear basis to be integral therewith. Each gear tooth includes a tooth top land and a tooth bottom land both in a slanting and curved manner relative to a center axis of the gear basis. The webbed spiral bevel gear includes a web portion formed at radially outer end portions of the gear teeth to be integral therewith and closing the tooth bottom lands at the radially outer end portions of the gear teeth. The web portion is continuous with the radially outer end portions of the tooth top lands. A profile of the radially outer end portion of the tooth top land of each gear tooth has two edges extending at a slant from each other and expanding in a direction of the web portion.
