Abstract:
Provided is a parking mechanism (90) that can be released with a small force. The parking mechanism comprises cams (80, 81) having a lock position (L), in which second teeth (91) of a sleeve (71) mesh with first teeth (13) of an idle gear (12) and second teeth (97) of a sleeve (72) mesh with first teeth (23) of an idle gear (21), and an unlock position (U), in which the second teeth and the first teeth are separated. First surfaces (95, 101) of the first teeth and third surfaces (92, 98) of the second teeth transmit torque in a direction of pressing on first and third surfaces, and second surfaces (96, 102) of the first teeth and fourth surfaces (93, 99) of the second teeth generate thrust for separating the first teeth and the second teeth in an axial direction in accordance with torque in a direction of pressing on the second and fourth surfaces.
