Abstract: A vehicle seat operating device has a reclining lever, a lifting lever and a getting in/out support lever for rotating a vehicle seat in a horizontal plane. A reclining lever operation surface and a lifting lever underside operation surface are accessible from a side of the seat. The getting in/out support lever has a recess section which is formed toward the front, and an operation surface which is a ceiling surface of the recess is accessible from the front. Side access to the operation surface is blocked by an out sidewall located on a seat width direction outer side of the operation surface. The getting in/out support lever is easily distinguished from the other two levers because accessible directions are different.
