PROBLEM TO BE SOLVED: To provide an automatic transmission that enables a seamless shift while suppressing a shift shock.SOLUTION: In an automatic transmission of the present invention, a groove crossing an axial direction is formed on an outer periphery of a clutch ring cam when a seamless shift is performed, and a first protrusion for guide can move to an axial disengagement side along the groove. The groove has a gentle slope part with a small angle of crossing an axial direction, and a steep slope part with a large angle of crossing the axial direction.SELECTED DRAWING: Figure 3 |
