1. An apparatus, comprising:
a damper provided to be fixed to a main housing;
a protrusion formed on a shift dial that is configured to rotate with respect to the main housing; and
an operation feeling generation part disposed in the shift dial and elastically supported by a spring assembly coupled to the main housing, a first end of the spring assembly being fixed to the main housing and a second end of the spring assembly being elastically coupled to the operation feeling generation part;
wherein the operation feeling generation part and the spring assembly are spaced apart from the damper and the protrusion;
wherein the protrusion is configured to reduce a return rotation speed of the shift dial by contacting the damper when the shift dial returns from a position of an Nd stage or a D stage to a Null stage or returns from a position of an Nr stage or an R stage to the Null stage;
wherein the protrusion is configured to pass while sliding an upper end of the damper so that when the protrusion passes while sliding the upper end of the damper, the damper is compressed or elastically deformed by the protrusion thereby reducing the return rotational speed of the shift dial due to a friction resistance occurred between the protrusion and the damper;
wherein the shift dial is returned by an elastic force applied through the operation feeling generation part from the spring assembly when an operating force from the rotated shift dial is released;
wherein the damper is configured in two and fixed to positions facing each other along a circumferential direction; and
wherein the protrusion is formed in two and configured to have one-to-one matching with the damper.
