PROBLEM TO BE SOLVED: To attain a stretcher of a wheelchair type which is friendly to a care receiver, can transfer the care receiver from a bed to the stretcher smoothly and comfortably and can be automatically transformed from a stretcher to a wheelchair. SOLUTION: The stretcher uses shifting sheets 1a, 1b, 1c, 1x and 1y for transfer. Platforms 3a, 3b and 3c for receiving the sheets of the stretcher are made as thin as possible. The flexible sheets are also connected to each other by using flexible long hinges and are fixed to a carriage as a foldable mechanism. The edge of the sheet facing the bed is formed into a loosely waved form and the sheet is made of a material which easily slips with the care receiver. The center of undulation of the sheet is allowed to match the center of undulation of the platforms. Not only driving of the sheets by the carriage but all the functional operations are driven by electromotive force. COPYRIGHT: (C)2010,JPO&INPIT
