<P>PROBLEM TO BE SOLVED: To provide a bed device capable of measuring precisely the weight of a user, while preventing a structurally unstable state. <P>SOLUTION: This device is equipped with a mounting frame, a load measuring means 16 provided on the mounting frame, and a floor plate body provided on the mounting frame so that the load can be measured by the load measuring means. The load measuring means has a load cell 18 mounted on the mounting frame, a flange bearing body 35 having a flange 37 mounted on the floor plate body and a radial bearing 39 provided in a mounting hole 38 of the flange, a large-diameter shaft part 23 connected with the vertical axis to a free end receiving the load of the floor plate body of the load cell, and a tapered shaft part 25 connected to the large-diameter shaft part through a step part 24. The tapered shaft part is constituted of a load receiving shaft 22 inserted into the radial bearing and supported, for receiving the load of the mounting frame by the step part through the radial bearing and transferring it to the load cell. <P>COPYRIGHT: (C)2008,JPO&INPIT |
