装置。 A device for measuring frictional torque between a screw shaft and a nut screwed to the screw shaft, the device comprising: a support body in which two screw shafts to which the nuts are screwed are arranged parallel to each other; A rotary drive means that rotates one of the screw shaft and the nut synchronously and causes the other side to screw in the same direction, a connecting member that connects the other screws with each other, and a connecting member that is provided between the connecting member. What is claimed is: 1. A device for measuring friction torque of a screw element, comprising: a detection means for detecting the sum of friction torque between both screw shafts and the nut as an amount of deflection acting on a connecting member.
