  • Patent number: 11007872
    Abstract: Rattling of a shift body in a second direction is suppressed when movement of the shift body toward one side in the second direction is restricted. In a shift lever device, a projecting portion of a hook of a lever projects toward the left from the lever. When disposing the lever on an R position side from an N position, a leading end face of the projecting portion is restricted from pivoting toward the left side by a right face of a rear restricting portion of a left plate, such that a pivot operation of the lever toward the right side is restricted. Flexing of the hook can thereby be suppressed, enabling rattling of the lever in a left-right direction to be suppressed.
