A shaft sealing structure for a rotation shaft, includes a sealing ring having ends formed by removal of its part. The ends abutting each other are continuous in the circumferential direction when the sealing ring is reduced in diameter to a radially inner side. The sealing ring is provided along the circumferential direction of the rotation shaft so as to be contactable with an outer peripheral surface of the rotation shaft. The structure also includes a pressing member configured to be movable between a pressing position and a retracted position; an elastic member configured to bias the pressing member toward the pressing position by elastic force; and a support member configured to support the pressing member at the retracted position against the elastic force, and to allow the pressing member to move to the pressing position at a predetermined temperature.

This cylindrical cutter for skiving comprises a plurality of cutting edge parts in the circumferential direction by having tooth grooves be formed between circumferentially adjoining cutting edge parts with the tooth grooves being formed into a helical shape twisting in the axial direction. Cutting edge grooves are each formed in the cutting edge parts so as to divide the cutting edge parts into multiple sections in the length direction of the tooth grooves.
