PROBLEM TO BE SOLVED: To provide a plate temperature measurement device designed to be able to measure the temperature of a plate stably.SOLUTION: Provided is a plate temperature measurement device for measuring the surface temperature of a plate 20 in a friction type coupling mechanism 6 capable of coupling two members 40, 50 by pressure-welding a plurality of plates 20 with each other that are disposed between the two members 40, 50 at least one of which is rotatable, the plate temperature measurement device comprising a disposition passage 21 formed inside at least one of the plurality of plates 20 along the radial direction of the plate 20, and a thermoelectric couple 10 the tip part 10A of which is placed in a radial middle part of the plate 20 and the base end part 10D is led out to the outside of the plate 20 via the disposition passage 21, a portion of the thermoelectric couple 10 present inside the disposition passage 21 being fixed in place, with tension applied thereto, so as to have a space 23 between the inner wall 21a of the disposition passage 21 and itself.SELECTED DRAWING: Figure 4 |
