Summary:PROBLEM TO BE SOLVED: To prevent the generation of dispersion of measured value by measuring load by a pressure sensor mounted on a truck, fitted with a foreign material load detecting fitting in a guide sill groove, through a slider. SOLUTION: A load cell 8 is mounted on a truck 4, traveling on the upper part of a door sill 2, through a slider 7. A foreign material load detecting fitting 1 is fitted to the truck 4 and installed at the truck 4 by an attaching screw. At the time of detecting foreign material load, the load cell 8 part is gripped by a hand to make the truck 4 travel on the sill, and the foreign material load detecting fitting 1 part is pressed to the foreign material. Load loaded to the foreign material load detecting fitting is converted into load by the load cell, and this value is measured by a measuring instrument and an indicator. Since the load of the foreign material caught in the sill does not differ depending on a measurer, foreign material detecting accuracy is improved.
