Description of the Invention: The present invention relates to a pressing force measuring device for measuring a pressing force of a pressing mechanism that generates a pressing force occurring between members. [Prior Art] An example of a device having a pressing mechanism that generates a pressing force between members is, for example, a sliding nozzle device (hereinafter referred to as "SN device"). Since the SN device has the advantage of being able to accurately control the flow rate of the molten metal, it is widely used in molten metal containers such as steel melting pots and casting trays. This SN device 'has two or three pallets, and the surface pressure (pressing force) is applied between these pallets. In Fig. 8, the general configuration of an SN device having two pallets is shown. The same figure (a) is a cross-sectional view seen from the front, and (b) is a cross-sectional view seen from the side. The SN device shown in Fig. 8 is used for flow control of molten steel discharged from an example of a molten metal container, that is, a casting tray, and includes a fixed metal frame 2 fixed to the bottom of the casting tray 1, and The opening and closing metal frame 3 that is connected to the fixed metal frame 2 in an open and closed manner, and the sliding metal frame 4' that is slidably disposed in the opening and closing metal frame 3 are placed on the fixed metal frame 2, and the sliding plate 3 is placed on the sliding metal frame 4. Configure the lower pallet 6. By the plucking force of the coil spring 7 attached to the opening and closing metal frame 3, the lower tray 6 is pressed upward by the opening and closing of the metal frame 3 and the sliding metal frame 4, and the surface pressure is applied between the pallets. -5- 201209384 The surface pressure between the pallets in such an SN device can be measured by a load sensor. Specifically, as shown in FIG. 9, two adjustment iron plates 8a and 8b are disposed between the fixed metal frame 2 and the sliding metal frame 4, and a load sensor 9 is disposed between the adjustment iron plates 8a and 8b. . At this time, the total thickness of the iron plates 8a and 8b and the load sensor 9 is adjusted so that the adjustment iron plate 8a is adjusted so as to be equal to the total thickness of the upper pallet 5 and the lower pallet 6 as shown in FIG. The thickness of 8b. Further, the surface pressure generated between the pallets was measured by the load surface pressure in the state of Fig. 9. However, in the SN device, although the load surface is pressed between the pallets by the plucking force of the coil spring 7, the plucking force is obtained by compressing the coil spring 7. Therefore, in the SN device, a surface pressure load mechanism that compresses the coil spring 7 is required. In this surface pressure loading mechanism, it is manually generated and automatically generated. In the surface pressure load mechanism that is manually generated, it can be pressed on the pallet load surface in a stationary state, but in the automatically generated surface pressure load mechanism (hereinafter, "automatic surface pressure load mechanism"), the "almost case" is borrowed. The load surface pressure is slid by sliding the sliding metal frame 4 (for example, refer to Patent Document 1). However, in the SN device using the automatic surface pressure load mechanism that slides the sliding metal frame to load the surface pressure as described above, the surface pressure generated between the pallets is measured by the method of the above-described Fig. 9, because of the load surface pressure. When the sliding metal frame 4 slides, the lateral force is applied to the load sensor 9, so that the measurement of the surface pressure becomes impossible. If the measurement is to be barely measured, the load sensor 9 may malfunction or be damaged. [Prior Art Document] 8 -6-201209384 [Patent Document] [Patent Document 1] WO2002/090017 SUMMARY OF THE INVENTION (Problems to be Solved by the Invention) An object to be solved by the present invention is to provide a press The pressure measuring device, such as the automatic surface pressure load mechanism in the SN device, can be measured in the first pressing member by sliding the second member against the first member to cause a pressing force between the first member and the second member. And the pressing force between the second members. (Means for Solving the Problem) The pressing force measuring device according to the present invention measures the first and the pressing means for causing a pressing force between the first member and the second member by sliding the second member against the first member. The pressing force generated between the second members is characterized in that the adjustment plate is provided with the first member held by the first member or the first member held by the first member and the second holder held by the second member. And the sliding plate is disposed so that the adjustment plate is relatively movable in the sliding direction of the second member and relatively movable in the direction in which the pressing force occurs; and the load sensor is disposed on the adjustment plate and When the pressing force is generated between the adjustment plate and the slide plate by the pressing mechanism, the slide plate relatively slides in the sliding direction of the second member. [Effects of the Invention] In the present invention, since the adjustment plate, the slide plate 201209384, and the load sensor are disposed as described above, when the slide plate relatively slides in the sliding direction of the second member, the adjustment plate, the slide plate, and the load are applied. The sensor slides integrally, so the lateral force does not act on the load sensor. Therefore, even in the pressing mechanism that causes the pressing force to be generated between the first member and the second member by sliding the second member to the first member, the pressing force generated between the first member and the second member can be measured. [Embodiment] Hereinafter, embodiments of the present invention will be described based on the embodiments shown in the drawings. [Embodiment 1] Fig. 1 is a view showing a first embodiment of the present invention. In this embodiment, the pressure measuring device of the present invention is applied to a surface pressure measurer between the pallets of the SN device, (a) of Fig. 1 is a cross-sectional view seen from the front, and (b) is seen from the side. Sectional view. Further, since the configuration of the SN device is the same as that of the eighth embodiment, the same configuration as that of the eighth embodiment is denoted by the same reference numerals in the first embodiment, and the description thereof will be omitted. The pressing force measuring device shown in Fig. 1 is composed of an adjusting plate 10, a sliding plate 11, a load sensor 9, and a fixing plate 12, and is disposed in a fixed metal frame 2 and a sliding metal of the SN device. Between boxes 4. The adjustment plate 10 is disposed between the fixed metal frame 2 and the sliding metal frame 4. This adjustment plate 1 is disposed for the slide metal frame 4 so as not to be relatively movable in the sliding direction thereof. In one aspect, the adjustment plate 1 〇 is fixed 8 -8- 201209384 in the sliding metal frame 4 is also possible. The slide plate 11 is disposed on the adjustment plate 10. The slide plate 11 is movably movable in the sliding direction of the slide metal frame 4 with respect to the adjustment plate 10, and is relatively movable in the load direction of the surface pressure (the direction in which the pressing force is generated). Specifically, the slide plate 11 is disposed between the pair of guide portions 10a and 10b that are vertically raised from the adjustment plate 10. The pair of guide portions 10a and 10b are provided at intervals in the sliding direction of the slide metal frame 4, and the intervals are formed to be almost the same as the length of the slide plate 11 in the sliding direction, and the slide plate 11 is fitted in a pair of guides. Between l〇a, l〇b. Thereby, the slide plate 11 is relatively movable in the sliding direction of the slide metal frame 4 with respect to the adjustment plate 10, and can be relatively moved in the load direction of the surface pressure. The load sensor 9 is disposed between the adjustment plate 10 and the slide plate 1 1 . Further, the fixing plate 12 is fixed to the fixed metal frame 2. Moreover, the total thickness of the adjustment plate 10, the slide plate 11, the load sensor 9, and the fixed plate 12 is adjusted so that the total thickness of the upper pallet 5 and the lower pallet 6 shown in FIG. 1〇, the thickness of the sliding plate or the fixing plate 12. The SN device shown in Fig. 1 is provided with an automatic surface pressure load mechanism. That is, by sliding the sliding metal frame 4, the surface pressure is applied between the fixed metal frame 2 and the sliding metal frame 4. Therefore, as shown in Fig. 1, after the pressure measuring device is placed between the fixed metal frame 2 and the sliding metal frame 4 in the state where the surface pressure is not loaded, the sliding surface metal is shown in Fig. 2 Box 4 will be in a sliding state. At this time, in the present embodiment, since the adjustment plate 10, the slide plate 11, and the load sensor 9 are disposed as described above, when the slide plate 11 is slid by the sliding of the slide metal frame 4, the adjustment plate 10 and the slide plate are used. £: -9- 201209384 11 and the load sensor 9 will slide integrally 'so the force in the lateral direction does not act on the load sensor 9. Therefore, the surface pressure applied between the pallets of the SN device can be measured without any problem. Further, in the above embodiment, the adjustment plate 10 is disposed on the slide metal frame 4, and the fixed plate 12 is disposed on the fixed metal frame 2. However, as shown in Fig. 3, the adjustment plate 10 is disposed. The fixing metal plate 2 may be disposed on the sliding metal frame 4 in the fixed metal frame 2. Fig. 4 is a view showing another configuration example of the adjustment plate 10 and the slide plate 11. In the example of Fig. 4, a pair of guide portions 11a and lib are provided on the slide plate 11, and the tip end portion thereof is retractably fitted into the adjustment plate 1A. With this configuration, the slide plate 11 also moves to the adjustment plate 10 so as not to be relatively movable in the sliding direction of the slide metal frame 4, and can be relatively moved in the load direction of the surface pressure. Further, in the example of Fig. 4, the adjustment plate 10 is disposed on the slide metal frame 4, and the fixed plate 12 is placed on the fixed metal frame 2. On the contrary, as shown in Fig. 5, the adjustment plate 10 is disposed. The fixing metal plate 2 may be disposed on the sliding metal frame 4 in the fixed metal frame 2. In the examples of the third to fifth embodiments described above, similarly to the example of the first embodiment, when the sliding plate 11 is relatively slid by the sliding of the sliding metal frame 4, the adjusting plate 1 〇, the sliding plate 1 1 and the load are applied. Since the sensor 9 slides integrally, the force in the lateral direction does not act on the load sensor 9. Therefore, the surface pressure applied between the pallets of the SN device can be measured without any problem. Further, in the above example, the fixing plate 12 is not necessarily required, and the fixing plate 12 may be omitted as long as the sliding plate 11 can be directly slid to the fixed metal frame 2 or the sliding metal frame 4. However, it is preferable to use the fixing plate 1 2 to make the sliding of the slide plate 11 smooth. [Embodiment 2] Fig. 6 is a view showing a second embodiment of the present invention. In the present embodiment, the pressing force measuring device of the present invention is applied to the pressing force measurement between the lower nozzle and the dipping nozzle, wherein (a) of Fig. 6 is a cross-sectional view seen from the front side, and (b) is seen from the side. Sectional view. First, the joint structure of the lower nozzle and the submerged nozzle will be described with reference to Fig. 7 . The lower nozzle 13 is held by the nozzle holder 14 and joined to the lower portion of the lower tray 6 of the SN device. Further, it is joined to the lower submerged nozzle 15 of the lower nozzle 13. Further, the SN device shown in Fig. 7 is a three-plate type SN device including a slide plate 16 between the upper pallet 5 and the lower pallet 6. The head of the immersion nozzle 15 is covered by the metal shell 15a, and the head is pressed upward by the jig 17, and the immersion nozzle 15 is held against the lower nozzle 13. The jigs 17 are plural and are disposed on both side portions of the immersion nozzle 15, and the urging force of the coil spring 18 causes the upward pressing force to occur. The joining of the lower nozzles 13 toward the dip nozzle 15 is performed using the guide rails 19. In other words, the immersion nozzle 15 is moved along the guide rail 19 in the direction of the arrow in Fig. 7(a), and the head of the immersion nozzle 15 is inserted between the lower nozzle 13 and the jig 17, so that the immersion nozzle 15 is slid to the lower portion. Nozzle 13 By the sliding of the dipping nozzle 14, the pressing force generated by the jig 16 is loaded, and the dipping nozzle 14 is pressed against the lower nozzle 13. The pressing -11 - 201209384 force measuring device of the present invention for measuring the pressing force generated by such a pressing mechanism is as shown in Fig. 6, by: an adjusting plate 1 及, a sliding plate 1 1 , and a load sensor 9 Composition. The adjustment plate 10 is disposed between the lower nozzle 13 and the jig 17. This adjustment plate 1 移动 is movable along the guide rail 19 in the same manner as the immersion nozzle 15 shown in Fig. 7. The slide plate 11 is disposed on the adjustment plate 1A. The slide plate 11' is movably opposed to the adjustment plate 10 in the sliding direction of the above-described immersion nozzle 15, and is relatively movably disposed in the direction in which the pressing force generated by the jig 17 occurs. Specifically, the slide plate ’ ' is disposed between the pair of guide portions 10a, 10b which are vertically raised from the adjustment plate 10. The pair of guiding portions 1 Oa, 1 Ob are provided at intervals in the sliding direction, and the intervals are formed to be almost the same as the length of the sliding plate 11 in the sliding direction. The sliding plate 11 is embedded in the guiding portion 10a , 10b. Thereby, the "sliding plate 11" is relatively movable in the sliding direction of the immersion nozzle 15 with respect to the aligning plate 10, and is relatively movable in the direction in which the pressing force generated by the jig 17 occurs. The load sensor 9 is disposed between the adjustment plate 10 and the slide plate 11. Further, the total thickness ' of the adjustment plate 1 〇, the slide plate 1 1 and the load sensor 9 is adjusted so as to be equal to the total thickness of the head portion of the immersion nozzle 15 shown in Fig. 7 or It is the thickness of the slide plate 11. As described above, the jig 17 is caused by the pressing force by sliding the dip nozzle 15 to the lower nozzle 13. When the pressure is measured, the pressing force measuring device of the present embodiment constituted by the adjusting plate 1 and the slide plate 11 and the load sensor 9 is slid in the same manner as the dipping nozzle 15. At this time, since the adjustment plate 10, the slide plate 11, and the load sensor 9 are integrally slid, the force in the lateral direction does not act on the load sensor 9 8:12 - 201209384. Therefore, the pressing force generated by the jig 17 can be measured without any problem. BRIEF DESCRIPTION OF THE DRAWINGS [Fig. 1] shows a first embodiment of the present invention in which the pressure measuring device of the present invention is applied to the surface pressure measurement between the pallets of the SN device.
