  • Publication number: 20210148455
    Abstract: A rattle reduction device for a dial type shifting apparatus is provided and includes a damper provided to be fixed to a main housing, and a protrusion formed on a component configured to rotate with respect to the main housing and configured to reduce a return rotation speed of a shift dial by contacting the damper when the shift dial returns from a position of a Nd stage or a D stage to a Null stage or returns from a position of a Nr stage or a R stage to the Null stage, thereby reducing rattle.
