PROBLEM TO BE SOLVED: To prevent the generation of decubitus, to easily move the body of a user from a supporting base, to prevent a column from recklessly falling and to improve safety. SOLUTION: The column 10 is freely erectably and fallably erected on both sides of the supporting base 2, rotary shafts 3 are parallelly arranged on the upper end of the column 10, a sheet 5 is disposed between the rotary shafts 3 and the sheet 5 is moved in a width direction accompanying the rotation of the rotary shafts 3. In this case, a supporting plate 7 is extended from the outer side face of the supporting base 2, the lower end part of the column 10 is formed vertically movably and rotatably outward facing one surface of the supporting plate 7 and a locking projection 9 is projectingly formed on the upper end outer side of the supporting plate 7. Then, the column 10 is provided with an engaging shaft 8 to be locked to the inner side end of the locking projection 9 when the column 10 is lowered and to be reached to a position higher than the locking projection 9 when the column 10 is raised. |
