[Prior art]

 Conventionally, seats for vehicles such as airplanes and vehicles have been configured with individual TV receivers for each seat. For example, between seat backs with two or three seats. There is proposed a structure in which a relatively long support arm is attached to the front end of the TV receiver, and the TV receiver is fixedly supported at the tip of the support arm, and the TV receiver is moved to the passenger's front side by viewing by rotating the support arm. ing. However, with this type of structure in which the TV receiver is fixedly supported at the tip of a comparatively long support arm, the TV receiver is always exposed between the seatbacks even when the TV receiver is not being viewed. In addition to the poor usability of the seat, there is a drawback in that the mounting structure by the support arm itself becomes large. Therefore, we propose a television receiver that is normally stored inside a center armrest that is constructed between multiple seats, so that passengers can take it out from the center armrest for viewing as needed. Has been done. In the television receiver having such a structure, a concave portion is formed in the lower portion of the cartridge tray, which is provided in the upper front portion of the center armrest and on which food and drink containers are placed, and a hinge mechanism is formed at the upper front portion of the concave portion. The TV receiver is configured so that it can be freely moved in and out of the recess.
