An internal gear shaving machinewhich brings a shaving cutterand an internal gear held by a workpiece chuckinto engagement with a crossed axes angle, and subjects the tooth flanks of the internal gear to final machining while it rotationally drives at least one of the shaving cutterand the workpiece chuck. The workpiece chuckand shaving cutterare supported movably toward and away from each other in a vertical direction with the workpiece chuckhigher and supported movably in the horizontal direction relative to each other. The workpiece chuckis constituted to hold the outer circumferential surface of the internal gear with the axis of rotation of the internal gear oriented in a up-down direction so that shavings produced during processing by the shaving cutter can fall downwardly from the internal gear.
