Proposed is an operation apparatus for a vehicle, the apparatus includes a panel with an opening, an operation module capable of moving, through the opening, between a first position and a second position spaced apart from each other in a front-back direction, a first rotary link and a second rotary link, each configured to be rotatably provided at a rear of the operation module and to be paired with each other, a drive source configured to provide a driving force for rotating the first rotary link and the second rotary link, and a cam mechanism configured to connect the first rotary link and the second rotary link to the operation module, to induce an angular motion in which the first rotary link and the second rotary link are rotated in opposite directions, and to move the operation module to the first position or the second position.
