A monitor stowage device for stowing a monitor into a stowage component, the monitor capable of being opened and closed. The monitor stowage device comprises a motor and an opening-closing mechanism. The motor supplies drive force to the opening-closing mechanism to open and close the monitor. The drive force from the motor is transmitted to the opening-closing mechanism, and the opening-closing mechanism changes the state of the monitor from a closed state to an open state, the closed state in which the monitor is stowed in a stowage space of the stowage component such that the long-side direction of the monitor is aligned with a direction substantially perpendicular to the width direction of the stowage section, and the open state being a state in which the monitor is deployed in such a manner that the long-side direction of the monitor is aligned with the lateral direction.
