Abstract
A fitting groove 46 comprised of a first groove 48 and a second groove 50 is formed in a holder connected to an operation knob. As a pin 54 of a shaft 52 is inserted in the fitting groove 46, the shaft 52 is connected to a holder 24, i.e., the operation knob. As a result, even in a shift-lock state in which the axial movement of the shaft 52 is prevented, it is possible to carry out without trouble the operation of selecting a shift position N, D, or 2 by the rotation of the holder 24 as well as the operation of selecting a shift position L involving the rotation and axial movement of the holder 24. In addition, it is possible to set a multiplicity of shift positions which are selected by the holder 24.
