Abstract
A tooth groove is provided at a border portion between a tooth body portion and a protrusion. The angle between a tooth body portion lateral face which is a lateral face in the circumferential direction of the tooth body portion and a tooth body portion stop portion which is a face, of the tooth groove, continued from the tooth body portion lateral face is the right angle or an acute angle. The protrusion is rotated toward the outer side in the circumferential direction, to bring a protrusion stop portion into close contact with the tooth body portion stop portion, the protrusion stop portion being an outer-circumferential-side lateral face of the protrusion, thereby forming a shoe in a tooth.
