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.

A bearing includes an inner ring and an outer ring arranged to face each other with a rolling element interposed therebetween, and a housing including a housing inner supported by the inner ring and a rotor flange supported by the outer ring. The rotor flange includes a flange portion extending toward one end surface side in an axial direction of the outer ring, and a C-type retaining ring arranged at the other end surface side in the axial direction of the outer ring. A push ring formed of a resin material is provided in a gap between the flange portion and the one end surface in the axial direction.
