Abstract

A lavatory unit for a vehicle is provided for washing feet. A toilet seat is put in the use position, a lid is put in the open position, the lid and a water drainage plate coupled by an engage/disengage mechanism are disengaged, and the water drainage plate is rotated to the placed position. With pressure on the water drainage plate, water is discharged from a faucet for a predetermined time by a water control unit, and the foot is washed on the water drainage plate. The water is drained to the inside of a toilet body through a discharge port. Once the foot is washed, the water on the upper surface of the water drainage plate is wiped, the water drainage plate is rotated from the placed position to the open position of the lid, or the lid is rotated to the closed position.
