A lid opening-closing mechanism of a container device for a vehicle, including: a container device body provided in a vehicle interior of a vehicle; a lid attached freely openable and closable to the container device body; an elastic member interposed and provided between the container device body and the lid configured to bias the lid in an opening direction and a closing direction of the lid with biasing force; and a bidirectional damper attached to the container device body configured to attenuate the biasing force of the elastic member with attenuating force, wherein the elastic member includes a reversal spring in which biasing directions of the biasing force are reversible based on a reversal point in which one of the biasing directions is in the closing direction of the lid in a closed side of the lid of the reversal point and in which the other of the biasing directions is in the opening direction of the lid in an open side of the lid of the reversal point, and wherein the bidirectional damper includes a free-running section in which the attenuating force of the bidirectional damper is not generated in an early stage of at least one of the opening and closing of the lid.
