摘要： Disclosed is a shifting apparatus, including: sleeve gear having teeth provided on an inner circumferential surface of a sleeve; and a clutch gear having teeth provided on an outer circumferential surface of a clutch such that the clutch gear teeth are engaged with the sleeve gear teeth by movement of the sleeve in an axial direction. In particular, ends of the sleeve gear teeth facing the clutch gear, and ends of the clutch gear teeth facing the sleeve form flat surfaces perpendicular to the axial direction.
