A horizontal-type apparatus for stretching a centrum of a human body comprises a slippage bed and a stretching system. The slippage bed consists of bed feet, a bed frame (2), and a bed plate (3). A long hole is disposed in the bed plate (3). A straight line sliding assembly (4) is disposed below the long hole. The straight line sliding assembly (4) comprises a sliding rail (4.11, 4.12) and a sliding piece ((4.21) sliding along the sliding rail (4.11, 4.12). The sliding rail (4.11, 4.12) is fixed on the bed frame (2). A human body fixing piece is disposed above the long hole. A connecting piece (4.51) is disposed between the human body fixing piece and the sliding piece (4.21). The connecting piece (4.51) is disposed in the long hole. An upper end of the connecting piece (4.51) is connected to the human body fixing piece, and a lower end is connected to the sliding piece (4.21), and the connecting piece (4.51) slides in the long hole and drives the human body fixing piece to move when the sliding piece (4.21) slides. The apparatus has a simple structure, can effectively overcome the defects of large size and large occupied space of an existing stretching device, and can be commonly used at home or in office spaces.La présente invention concerne un appareil de type horizontal pour létirement dun corps vertébral dun corps humain, ledit appareil comprenant un lit coulissant et un système détirement.
