Abstract
The present invention is provided with: gear chamfering tools that perform cutting for chamfering a tooth profile ridge section of a gear to be cut; tool holding parts for holding the gear chamfering tools at one end portion thereof; substantially linear movement means which cause substantially linear movement of the other end portion opposed to the one end portion for holding the gear chamfering tools in the tool holding parts; and circular movement means for causing circular movement of an intermediate portion between the one end portion for holding the gear chamfering tools and the other end portion subjected to the substantially linear movement by the substantially linear movement means in the tool holding parts. By combining the substantially linear movement means and the circular movement means, substantially elliptical movement of tip end parts of the gear chamfering tools is achieved.
